Megajolt / MegaSquirt maps, Attach them here.

[DaveNotSoSideways]

Got any base maps, attach them here.

Map for 2L 6 pot on standard (vitesse mk2) internals.

 

Pretty close to standard dizzy curve.

 

Note this is a megasquirt map so the axes are reversed compared to Megajolt.

 

Also note that load sensing is via manifold pressure (MAP) not throttle position.

This is a base map for a 1.8 K-series Rover using VVC or big valve head and 270 degree SOLID cams, using throttle bodies or carbs in place of the normal plenum.

 

This is a NOT a conservative starting MAP!

 

This is for a MAP sensor Megajolt box.

Engine Mfg: Triumph

Engine Code: FM

Cylinders: 4

Displacement (cc): 1500

Rev Limit: 6000 (ish)

TPS or MAP: MAP

Boosted or Normally Aspirated: NA

If Boosted- max Pressure (KPa):

Modifications: S/S 4-2-1 Downpipe to custom rear pipe and box, Twin 40 Dellorto's, Mechanical pump assembly removed, Electric Fan and Electric Water pump

 

Notes: The default Map worked fine but seemed to lack in top end power and splutter a bit on high load low revs, the new map seeds to have ironed these probs out. Maybe the 600rpm column could do with some work.

 

 

MAP can be downloaed from http://www.autosportlabs.org/viewtopic.php?t=1422 , please note not from me or tested on my spitfire.

[DaveNotSoSideways]

Tad too much advance at the top on that one, 37deg...

 

Just digging out some old maps.

[DaveNotSoSideways]

This map is what I was using in my 1300.

 

This map IS NOT advised for anything the cam/spec mentioned, it is NOT a SAFE starting map!

 

You may notice a very odd mapping in the 3000-4000 area, this RETARD was to avoid rough running in the useless torque spike area on the TH7. The only way to smooth the engine at motorway cruise was to retard then bring the advance back in @ 4000.

 

This gave my 42-44mpg at cruise, 117HP peak and ran like a clock. Pull off from stops without any revs on a race-cam.

 

Specs:

 

Twin Dellorto DHLA40C on 33mm chokes using 52idle, 7850.1 holder, 122main, 7 tube, 160 corrector, 35pumps.

 

1.5" inlet, 1.25" exhaust valve, fully modified race-head.

 

BP6ES plugs

 

10.5:1 compression.

 

Fully blueprinted and balanced, light flywheel.

 

GE herald small crank 1300 block.

 

TH7 300 degree small bearing KENT cam @ 103 install degrees.

 

Stock rockers and ratios.

 

NOT ADVISED for other specs! At your own risk, this map was on the limit, due to compression it was not possible to use more advance. I do not say its perfect, but it was MILES better than a 2D distributor setup.

[mattius]

This is my safe mode map for my 1500, still to play with it properly but works well as a starting point.

 

[mark spit]

Here we go then,

This is for a fast road 1300, 4-2-1, HS4s, AAU needles, 2R cam.

Working well for me.  For info the rev limit on this map is 6500rpm.

Attached a piccy of the values and also the map file itself, note, my megajolt program gives the files a .mjlj extension rather than the cfg as it is here, however the program opens it up ok anyway.

 

Have fun

[DaveNotSoSideways]

Looks fine. I am quite sure you could get some bigger numbers in the 60-50-40-30 and below areas, but thats mostly emissions as mentioned before in the "vacuum advance thread". No doubt your map is an improvement, you now have actual control from the crankshaft...Its gotta be miles better eh...The timing isn't coming through a wonky chain, along a cam, through a drivegear, through a shaft, through a swivel section, through weights and springs and controlled by a set of flappy points.

 

Its gotta be better!

[mark spit]

so much better, more than expected actually - not often that happens.

[DoZ]

Here is my first attempt.

 

This is for a gt6 with the following engine:

2500s engine

lightened flywheel

balanced

hs6 carbs

TR5 cam

 

[DoZ]

Sorry, turns out you cant attach png file, so here's the gif

[Mother Teresa]

Not base map- but where I am currently ;D. Attached it elsewhere, but here seems more sensible.

DoZ: my car seems to run at a different vacuum to most here(make that all of 'em!). Some cars tickover at 30, some at 40, some 50....

Mine runs from tickover 75, to 102 'giving it death'. Part-throttle (coasting downhill) is something like 40 Kpa.

Within reason, it doesn't matter what it ticks over at, unless the reading is indicative of an air leak somewhere.  

Mine ticks over very nicely now at 73-74 Kpa, gently fluctuating . It has the in-line restrictor and a small regulator box. The take-offs from the inlet manifold are all at the cylinder head and linked together properly in series.

My two litre engine runs triple SU's, on a TH5/TT FR83 cam shaft with C/R of about 9.5.

 

 

 

[DoZ]

Here is my latest attempt which seems to be working well.

[SteveA]

Now that all the injection system is on my car and with help from GT, we have refined the ignition map for my GT6. So this is a map used with a standard GT6 MkII engine (two litre), cam and head, but with a proper exhaust manifold and Lucas mechanical injection.

 

[bonsaiisuperstar]

Anyone have a base map for a standard 72' spitty 1300. All original except the twin SU's? All these maps listed seem to be for your hotrods

[neilnaz]

Dave posted some in the stickies.........

[mark spit]

here's the one I used as a starting point on my 1300.

Change the extension to mjlj when you've downloaded it.

[James]

I found this the other day - looks interesting. Makes a map from the standard centrifugal and vacuum settings in the manual.

 

Anybody got dizzy details for a TR5?

[Nick Jones]

That's interesting - made something similar when I did mine.

 

Can't find any details on TR5 dizzy.  Selection of other stuff for comparison on Paul Teglers site and also the NZ Triumphs technical database.

 

My Vitesse map would probably be good enough for a starting point.

 

Nick

[James]

Yeah - looking at something to start on - figured that Tr5 is the wildest - but perhaps that's a bad thing!

 

I think I have a GT6 manual at home - Mk2 is second most aggressive I think.

 

[James]

Nick- megajolt has only 10 bins - your one megasquirt has 11! better do some math...

Hah, 12 actually.......... Using the wrong box 'O tricks  

 

Nick

[James]

I should just buy a Megasquirt shouldn't I?

 

Not sure I fancy the £400 expense just for ignition initially...
