    Everything works fine now, all electrical circuits, the change to VW Coil Pack and car is running nicely again......that was only after I had the car running like a dog for ages, wondering why it was running very, very rich to the point it was struggling to run at all. Then I wondered why the MAP sensor reading was around 1 bar........oh, that would be because I hadn't connected the tube from the plenum back into the sensor.......what a numpty.
  2. Rewire

    So my main winter project was to rewire the Herald, 20 years of adding various electrical items had left it like a birds nest behind the dash. I have run all the cables, connected fuse boxes and relays etc so now it was time to do some testing. The good news was that everything seems to work. Lights, Flashers, Heater etc etc. all good until I added fuses to power up the Microsquirt ECU. Turn on the ignition and you hear the Fuel pump kick in and then stop as it should, but if you turn on the indicators or hazards the the Fuel Pump powers up, Injectors Click and the IAC Valve open & closes in sync with the on/off of the flashers. You also get a similar thing when pulling out the main light switch to the on position, but with that it's just the once. 12v supplies and earths for EFI & everything else are separate, the only common areas are the fuse boxes below. The one on the left supplies everything ignition fed the one on the right perm lives.The fuse boxes are the type that are powered at a single point and then feed 10 fused connections to relays & electrical items. The Ignition fed fuse box is supplied by a 40amp relay. This is the Fusebox for everything EFI related I thought it may be low battery or bad earth, but have ensured both are fine, and I have retraced the wiring for flashers/lights and they are seem to be right. The only change on the EFI wiring has been relocation of the relays to a base in the centre of the car and I have swapped from EDIS/Ford Coil Pack to VW Coil Pack (No EDIS), the car starts but sounds like a bag of nails, but that maybe just to set-up of the new ignition, but I run out of time and had to leave for work. I will go back and recheck everything, but thought I'd ask the question here just in case there is something obvious it might be that I am just missing. Darren

    Dashboard all connected up and everything behaving normally now, so earthing was the issue. Thanks all for you input and encouraging me to recheck the earths! Next job is to see if the move from Ford Coil Pack & EDIS to VW coil pack is working OK. Darren

    Initially I though the rivnut was a good idea, newly drilled hole with fresh clean metal and the rivnut crimped in against it, but completely take the point it has the potential to work loose. I have now run a 30amp earth cable from the rivnut back to where the earth strap from the battery bolts to the body. From this point there is also an additional earth strap down to where the starter, backplate & bell housing bolt together and this is where all the EFI earths come to, so I'm now pretty confident that earthing is well covered....time will tell when I connect up the dash again to do some testing. Many thanks. Darren

    I added an additional earth strap from battery to engine a couple of years ago when the starter was intermittently lazy, this connected to one of the starter motor mounting bolts. The EFI earth's are a few bolts round on the bellhousing, so are nearby, but think it will be wise to use the same location for both. All the earth's for everything else are at one point behind the dash, bolted in to a rivnut. A chunky cable back to where the earth strap connects to the body can't do any harm either, so will do that also. Thanks for the replies. Darren

    I did probe the 2 relays whilst the flashers were on, the one that feeds the ECU, Injectors & IAC Valve was a constant 12.xx volt, the one that operates the Fuel Pump & 02 sensor which earths through the ECU was pulsing in time with the flashers. I could remove this relay though and the IAC Valve & Injectors would click in time. I didn’t try with just the ignition on again after I started the car this morning, when I got home this evening I tried again and it’s now not doing it all, how does that work?..... I think I’ll double check the EFI earthing, this has always been on a bolt through the bellhousing/engine backplate. I did disconnect it, shorten and connecting to a bolt further round that bolts through the bellhousing straight into the engine block, I guess there could be oiled in between the surfaces prevent a clean contact. Will have another play on Sunday. Darren
  7. 'standard' electronic ignition

    I know plenty have used the Accuspark units and found them ok, however my experience with anything Accuspark is that it's cheap rubbish and best avoided, I was told that some of the early 4 cylinder units were tested and the pick-up weren't at 90°. I used an Aldon Ignitor for over 10 years and that done a good job, have fitted Lumenition kits to friends cars and these have worked well too. These guys are also worth a try: http://www.h-h-ignitionsolutions.co.uk/ Darren
  8. I was contacted by a very sweet old lady from down in Plymstock, Devon who has recently had to give up driving and wanted help selling her 1979 Dolomite 1850, which she has owned from new. Anyone looking for a bit of a project? So here are the good and bad points... 2 Owners from new, but same family at same address Genuine 54000 miles Tahiti Blue I collected it as a non-runner, but just needed a fuel pump and it now starts on the key. Everything on the car seems to work, except the wipers which don't park. MoT expired July 2016 It does have some issues, which are: Bodywork 3 of the doors will need replacing, the other needs some repair work. Will need a new NS Sill and repair to rear arch Hole in boot floor where it meets the inner arches NS front wing has had a parking bump, but would pull out easy. Boot Lid corners need a repair Front valance needs a repair Inside A-Pillars also need welding Chrome is pretty good, but some trim will need replacing. Interior Drivers Seat is well worn Passenger Seat has a split as does the rear seat back Loads of pictures attached and a short video of her running. I have driven her for a couple of miles and she starts, drives and stops very well. This car is very savable and would make an excellent project. Customer is looking for around £950, but I'm sure she will take a sensible offer. If I can't sell it for her, then I may restore myself! Please message me if you're interested Video & Images below.

    Mine is wired up with the Fuel Pump relay which switches off after a couple of seconds if you don't crank the engine, but I must confess to bypassing this and powering up and leaving on for a bit when I was getting things set-up in the early days, but only a handful of times, but maybe that caused some damage. We'll see how it goes. Darren
  11. AFR Reading

    So I connect up my laptop to my ECU and the Dashboard AFR Gauge is red and off the scale, go into the AFR Table and it's where I expect it to be, plus the car is running just fine. Have loaded older tunes, created new project and even reloaded the firmware but the gauge on the dashboard is still way off. Any ideas what's causing this? Darren

    Just a standard length bung and the sensor is at around 1 O'clock. Darren

    Good news is that the new o2 sensor has done the trick and everything is working again. Not so good news is that I did have to pay some import charges which meant it was only a small saving on buying from a UK supplier, but no big deal. A bit curious as to why it only lasted a few thousand miles, will be more curious if this one does the same.... Darren
  14. AFR Reading

    Pretty confident the wiring is OK, has been working fine since conversion. I have used silicone spray in my garage, but not anywhere around the engine bay. I do use an additive: http://www.millersoils.co.uk/products/vspe-power-plus-multishot/624 but I did contact Millers to ask if it was safe with Injectors & o2 sensors, which they confirmed it was. New o2 sensor is due for delivery today, so should know by early next week it it was the problem. Darren
  15. AFR Reading

    No dilema Phil, just it's not working and I want to get it resolved within the warranty period of the controller. I appreciate the o2 sensor isn't critical as the car has been set-up on a RR, but it's a useful diagnostic tool if nothing else. I have a new Bosch sensor coming from across the pond for $63 delivered (hoping it sneaks through customs without any import charges ), so hopefully that will sort it. Thanks to all Darren

    Hi Nick, The AFR gauge had a max of 19 and the EGO volts a max of 5, so I extended both the gauge ranges and got readings of 19.6AFR & 4.99v, I also probed the o2 cable from controller to ECU and got 5v, so would seem TS is displaying correctly. Wiring looks sound and some jiggling around of cables at key points made no difference, so I'm back to thinking a sensor or controller fault. I think a new sensor is my best bet, just feeling a bit mean at the moment so hoping to find one cheap. If that doesn't sort it, then I'll have to return the controller for testing. Do you think I should disable the o2 sensor for now or turn down the ECU authority % right down in the EGO Control settings? Darren
  17. AFR Reading

    Everything I've done so far was with the car stationary and idling in the garage, so to see what the EGO correction was doing I had the laptop plugged in as I was driving. I could see that whatever the problem is, it's intermittent, as every now and then the AFR gauge would go back into the range you'd expect to see for a bit, then way off the scale again and then repeat this process for the whole journey. The EGO correction gauge was trying to richen the mixture when the AFR was reading incorrectly as expected, I also found a gauge to show AFR input voltage which mirrored what the AFR gauge was doing, so reading at 5v when the AFR gauge was off the scale and then around mid point when working normally. I'm now thinking that if this were a controller or sensor fault it would be wrong all the time, maybe it could be something as simple as connection or wire breaking down intermittently? Just a thought and a cheap fix. Darren
  18. AFR Reading

    Hi Nick, The car is going great, certainly haven't noticed any change in how she drives or a drop in economy but if it's only just happened maybe I wouldn't have. It's a good point about seeing what the correction is doing, will go for a drive with the laptop plugged in to see what it's says. Until such times I have this issue fixed, would it be better to disable the sensor or give it 0% authority? I have done the done the maximising accuracy routine, the differences are quite small so I don't think would account for how far out it is, but have always set it up that way. Hi Roger, Thanks very much for the offer. Is that the LD Performance meter from the controller kit you bought? IIRC they use a different Bosch sensor with a wider reading than the 10-20AFR that the LSU 4.9 does, so I'm guessing it wouldn't be accurate if used with the Spartan Controller. I wanted to bypass the ECU/Tunderstudio readings and use a gauge just to ensure there wasn't something random happening with the connection there, with a gauge connected it's displaying something direct from the controller, so if still wrong then it's definitely controller or sensor. I will see if I can get a voltage reading from the controller, that may just tell me that it's kicking out the full 5v. Will report back when I've had a chance to take a look. Thanks to both. Darren
  19. AFR Reading

    Does anyone know where I can get a cheap & cheerful Wideband AFR Gauge, just so I can see a reading other than the one in Tunerstudio? They all seem to be part of a kit, which i don't need. If I get the same readings on a gauge then it is definitely either the controller or sensor rather than any controller to ECU problem. The warranty return for my controller is in Canada, so a bit of a faf and costly to get it returned, so want to make sure before I go that route. Darren
  20. AFR Reading

    This is the response I got from the controller manufacturer in the US: The fluctuations are limited to low engine load at low RPMs. I do not know specifically about MS, but it seems to be trying to close loop control the AFRs to near stoich during light engine loads to reduce emissions and reduce gas consumption. Not exactly sure what he's trying to say tbh, but I guess he's referring to the EGO settings below, I haven't touched them so are what you get when selecting single wideband. Darren

    No direct connection AFAIK. Calibration is just by inserting the linear values. Controller supplier has replied overnight and seems to think it's sensor failure. Darren
  22. AFR Reading

    Hi Nick, I'm using the Spartan 2 Controller, this sends out 2 calibration voltages during start-up and you use these to calibrate. With the latest MSExtra firmware it does give you the option to retain calibration or not during the flash process, I have tried both ways and neither work. The gauge in TS displays the 2 calibration readings, it's just after that it goes off the scale. I'm leaning towards controller or sensor failure, but only because I can't think of anything else it could be. Next time I get an opportunity I will check voltages out of the controller to see if they are in the expected range. Darren
  23. Nother newbie

    Some interesting mods, are they electric window switches on the centre console? How is the twin tank arrangement set up? I think we all want to know more Darren

    Is working on my PC, but not Ipad, maybe just an issue for tablet & mobile users? Darren

    Likewise, the info I got from this site during my EFI conversion was invaluable, so donation worth every penny (or cent).... Keep up the good work. Thanks Darren
