Royboy66 Posted February 9, 2012 Share Posted February 9, 2012 Its not just you Mr Jones! Have u received Tims parcel! ? Link to comment Share on other sites More sharing options...
Nick Jones Posted February 9, 2012 Share Posted February 9, 2012 Yes, I have Tims ECU. Tomorrow I'll also have my stim back, so will hopefully get it checked out over the weekend. Though it occurs to me that I don't have a car to attach it to for the final testing as the PI has just a bare engine hung in it and the Vitesse is away in kennels.... I will be putting the PI back together though - provided it is dry and above freezing...... (not looking especially hopeful though - winter..... ) Nick Link to comment Share on other sites More sharing options...
Bobbyspit1 Posted February 11, 2012 Share Posted February 11, 2012 If its any of the Q3, Q5, Q9, Q10,or Q11 I have spares, arrived yesterday. Rob Link to comment Share on other sites More sharing options...
Nick Jones Posted February 12, 2012 Share Posted February 12, 2012 Seems to be mostly alive at least. Just trying rediscover the temporary mod that makes it work properly with the stim so I can get an rpm signal. What's with the D13 mod?

Just trying rediscover the temporary mod that makes it work properly with the stim so I can get an rpm signal. What's with the D13 mod? Cheers Nick I had full rpm on my stim with the board. No worries Nick, If you need any spares give me a bell, I have most for the MS board. The D13 part of the board was a funny colour before taking the Diode out, I could not get a decent solder joint on the board with the new diode, hence the modification. A little strange but does the job. Rob Edited February 12, 2012 by Bobbyspit1 Link to comment Share on other sites More sharing options...

Nick Jones Posted February 13, 2012 Share Posted February 13, 2012 Yet to be determined fully. The V/F converter chip is getting hot so is presumed dead. This is a bit of blow as it's the only component on the stim board that costs more than about 15p. Seems to be the result of the stim being knocked about a bit on its travels causing the tips of the tach-out driver transistor to be bent and touch - which I didn't notice until the damage was done. Changing the transistor (which was cooked) has not fixed it. None of this impacts on your ECU other than it prevents me from testing the bits I want to test..... New chip ordered from Rapid...... Nick PS, I know it is the 13th today so it's probably just my crappy luck, but do you have some kind of jinx.....? Link to comment Share on other sites More sharing options...
Bobbyspit1 Posted February 14, 2012 Share Posted February 14, 2012 Its already run on my stim and had no issues. Rob Hey Rob Thanks for the offer but I dont want to cook yours too!!! Link to comment Share on other sites More sharing options...
Nick Jones Posted February 14, 2012 Share Posted February 14, 2012 I know. I wanted to check that it would fire actual injectors with both banks and thus prove that the problems Tim has been getting are external to the ECU (or not, as the case may be). Unfortunately the Stim is refusing to supply a tach signal so it won't even try to pulse injectors..... Everything else works fine though. No problem connecting to the ECU with the computer....... I would just plug it into a car and try it, but one possible victim is not here and the other is not in a firing-up condition yet (but I'm working on it).

I would just plug it into a car and try it, but one possible victim is not here and the other is not in a firing-up condition yet (but I'm working on it). Nick My stim is REALLY trying my patience. Changed the frequency generator chip and transistor to night. Does it work? Does it hell. With the transistor removed the chip generates a pulsed output - so thats alive but I cannot get the amplifier bit to work. This irks me considerably as it's not complex! I think the issue may be that the Stim I have is version 2.2 and the latest schematic I can find on the web is V2.1. They are not the same but I've been working on the basis that they were very similar..... Maybe not siimilar enough. Schematic shows a 2N3906 transistor. Mine had a BC557A in it (but I have a vague memory I did that). If anyone has a Ver 2.2 stim it would be much appreciated if you could read the transistor number of the flat side and also confirm that the transistor is mounted as shown on the silkscreen. If anyone has the Ver2.2 schematic that would be even better - but there doesn't seem to be one online (amazingly) even a couple of queries on the MS forum have drawn a blank.....

Bobbyspit1 Posted February 16, 2012 Share Posted February 16, 2012 (edited) Nick I built my Megastim V2.21 nearly 18 months ago and cannot find the build instructions, I assume you mean U1 as it is the only item on the board that has any writting on it. If so it says AD654 JN #0748 1323862 Just found Q1 2N 3906 G11 Hope this helps? Rob Edited February 16, 2012 by Bobbyspit1 Link to comment Share on other sites More sharing options...
Bobbyspit1 Posted February 16, 2012 Share Posted February 16, 2012 PS Nick, I has both injectors lighting my stim up on Tim's MS. ROb Link to comment Share on other sites More sharing options...
Nick Jones Posted February 16, 2012 Share Posted February 16, 2012 Yes, Q1 is the one - thanks! Going over to my father s at lunch time to try it in the Vitesse - direct methods! Had enough messing about! Cheers Nick Link to comment Share on other sites More sharing options...

Nick Jones Posted February 16, 2012 Share Posted February 16, 2012 Went over at dragged the Vitesse out of it's kennel. Initial start was on it's own ECU, but once I got it in daylight out I swapped them over..... .......and it fired up perfectly well on Tims too. So there's nowt wrong with your ECU Mr Walker (thanks due entirely to Mr Southern!). You'll need to swap the required fuel setting back to 14.7 (it's at the Vitesse 10.4 setting now). On it's way back to your work address now by special post so you should have it tomorrow. I've also put my spare USB converter in the box. This is one that works for me without any issues at all, so hopefully it will for you too...... My apologies for the time taken - should have done this first! I think you need to go through the wiring again, including the relay box itself (I've seen a couple of comments on the MS forum that seem to be similar to your issues that have been relay box related) and also the ECU - relay box cable. I really don't think the problem is in the ECU itself. Looking forward to triumphant stories of successful fire-up, successful tweaking, driving etc!

Bobbyspit1 Posted February 16, 2012 Share Posted February 16, 2012 Thanks Nick, Glad to know I can do somthing right Cannot wait to get my zetec megasquirted, Been working on my inlet manifold and plenum yesterday, getting there slowly. Link to comment Share on other sites More sharing options...
bestquality03 Posted February 17, 2012 Share Posted February 17, 2012 (edited) Thanks again to both Nick and Rob for your help. I never doubted Robs repair but just wanted to know that it worked on a real car rather than just the stim ECU arrived this morning so looks like I'll be having a "POETS" day today Edited February 17, 2012 by bestquality03 Link to comment Share on other sites More sharing options...
