ok

well i have just removed my complete install ready to start again making sure everything is connected and wired properly.

just have to hope i find the problem.

if its not a bad connections any ideas on what could cause this?

so really the only logical explanation is a broken loose wire?? either on the CPS or the PIP/SAW signal cable?

ok i'll give all the wires a good check, and change the load values to 10 everywhere if this makes no difference, you say it could be a sync problem, how can this be if the can runs 'ok' in limp mode?? absoultley nothing on the car had changed when i got this misfire in the beginning, i just cant un...

bizarre isnt the word!

PIP/SAW wire runs along the bulk head. nowhere near anything other than the brake servo.

the engine ran fine on the old plugs then started to miss, so i changed them for the excat same ones. and it made no difference...

out of options now.

right.... the rev on the megajolt software is jumping from around 1k up to 4k in surges, which like you sya is causing the timing jump around. i agree with the rev counter on the car. i dont know how to solve it though. i have deleted the map on the MJ and re put on the map. made no difference. than...

The rev counter on the car is wired from the megajolt.

Yeah the map sensor did as you describe.
I have checked the PIP/SW wire and can't see any damage, but I'll check again.

Thank you for the help

ok

just ran the car with it at 2k. the runtime graph is all over the place.

the map sensort reading stays pretty constant, but the rev and ignition advance jump about all over the place. but the rev counter on my clocks in the car stay quite still.

stuck for ideas now,


thanks chris

i had the car ticking over and a strobe on each lead in turn, and eeach lead had a mis fire.

i'll check the software in a bit and report back.

thanks for the help.

its a map type. i brought it from trigger wheels.

it ran perfect up until a couple of days ago..

running a MJLJ map type on my zetec. when running the engine without the MJ connected the engine runs fine in limp mode. as soon as i connect the MJ it starts to miss fire badly and will not run properly. it was all working fine until one day it just started miss firing out of th blue. checked all t...
