Not Running to healthy

[Tony C]

Rob,
if i wanted to bypass the cdi unit and connect the trigger wire for the vems to the coil, so i am only using the dizzy and coil setup. do i need to change any settings in MT?

[Tony C]

We may have a result,
on stripping down the engine today i have found that one of the adjustable pushrods on cylinder No2 the lock nut has failed and wound the pushrod open thus making the preload to much like jorgen said,

As soon as Rob sends the ecu back (is there a mail service that delivers over bank holidays :D :D) i will fit it all back up and try her again, fingers crossed this is the fault, which looks like it is our problem,
thanks to all sugestions made, and yes it looks like an engine component had failed and not the ecu, sorry if i doubted it  :'( :'(

We were discussing your setup today, and Jorgen pointed out to me that going from CDI to wasted spark is a retrograde step and that you've probably got all you need with your setup to have VEMS control the ignition without the crank pulley and all that extra 'stuff'.

What are you running for your ignition?

I get worried when people start talking about me  ::) ;D
my ignition consists of the following:

Because of significant changes in the configuration of anti-lag turning it off through MegaTune doesnt work when you've upgraded from pre 1.0.3x

When I return the VEMS to will recieve what all new purchasers get:
A CD with the Software release and the configs&tables that the unit was shipped with.
A calibration sheet detailing the settings and tests made on your system.

The fuel pump driver is a complete chip: the p259, and I didnt get a chance to test it last night, but I did'nt see that the earths on the harness were not joined:


This would account for the p259 dieing in the event of an earthing problem.  It might also explain the noisey signals that we saw, but again these wouldnt be sufficient to cause the problems you've been having.

I didnt test with the loom as I wanted to isolate the VEMS first.  I'll look at the loom next.

ECU came back today, cheers Rob,
was no CD etc in the box? or did you forget mate :)
also did you do that earth mod you talked about on the phone, you was going to unwrap the loom and twist a bit of wire somewhere etc and solder? if not where do i need to do the work mate?

[[email protected]]

The earth mod was done, I taped 3 of the wires together, and taped it up then rewound the plastic covering back on.

I ran out of CDs on Monday when I was packing things up and havent had a chance to get any (and that includes nicking them from work) because they want to see if they can kill me at work by making me actually do some... >:(

You can download what would have been on the CD from here:

You got the calibration sheet in the envelope?

Rob

[Tony C]

envelope?
never see any envelope mate :(
i have changed them 4 seperate crimped wires by joining them to a 6mm cable that will now go to the head instead of all the others.

[Tony C]

just found an envelope on the frotn of the box, just thought that was an address label :)

[[email protected]]

Far be it from me to point out the words: Documents Enclosed that were on the front of the envelope :P ;)

[Tony C]

i didnt look mate, :-[ :-[
was to eager to get the ecu out and back in the car  ;D ;D

[Tony C]

well she is 90% back together,
i took the time tonight to tidy up the existing looms while the vems ecu and its loom was out,
looking a lot tidier now :D
should be ready for a fire up late friday. failing that defo on saturday.

[Tony C]

the car lives, :D
runs sweet,
BUT have now got an idle valve problem,:(
it does not move any more, have tried another motor but have the same problem,. you can here the motor buzz as if its trying to move but thats all.
i have had to unscrew the stepper motor out of the housing a bit to open up the air channel to get her to idle,
any ideas before i start ripping the loom apart etc,
oh robs upgraded me to the firmware 1.0.73 while he had my ecu,
