I have a small turbo ESCOS, with some mods, Chipped ECU ( stage 2) Hybrid turbo, uprated fuel pump etc,,,

had it on the rollers and I have a problem with the ignition timing , advance/retard, not being vairable and is staying at 6 degrees all the way through the throttle position

has anyone came across this problem before , and what was the solution, we removed the uprated chip and tried another power run , but no change. Due to the problem with the ignition timing , the car is making way less than what it should.

I may need to take it to someone who has EEC4 software to download the fault codes, but I would really appreciate advise if anyone had came across this before

cheers

 

Mate if i were you i'd take it or mail it to Motorsprort Developments pronto before any damage gets done.

Stu and Kenny will sort it for you im sure.

 

^^^ What he said ^^^

 

Fixed at 6 degrees is very odd. A couple of simple things to try; running it without the chip first and then replacing the EDIS next.

 

Ran the car with the chip removed frm the ECU, with no change at all, initially that was what the problem was thought to be

EDIS unit, whats that mate, sorry for my ignorance, but certainly not that clued up on the car at the moment

The car is only running 12 psi of boost at the moment and the fueling is a little rich, and the tuner never seemed overly concerned about using it with the problem,

 

The EDIS is the 'ecu' that part controls the ignition. It looks like this

The loom plug has been cut off at the wires and left on in this picture (not by me I hasten to add).

 

think i may have a edis unit if your wanting one??

EDIT: i have found my old one gimme a pm if your interested

 

It might be running in LOS mode - which is why the timing is set to a static six degrees.

Halfords do a reasonably priced fault code reader which is compatible with the EEC-IV cossie

 

In LOS, the timing is fixed at 10 degrees. The engine would be running really rough with injection pulsewidth tied to rpm.

 

The car is running fine, just feels a little sluggish to me, doesnt have the same kick usually from a cosworth.

Thanks very very much for the advise guys, hopefully have it checked tomorrow and see what the fault history shows, and with it a solution to the problem all going well

 

Seconded. Very odd indeed. Never seen that one before.

 

Stu, I was on the phone on Monday and got some good advise.

its booked into a garage on Wednesday in Scotland who recon they have the gear to carry out a diagnostics, so ill give them a try first.

Failing that , its a dirty weekend in Blackpool coming soon

 

I hope they fix it then.

 

got some more info on this please mate?

 

i have a fault code reader from halfords which i no longer use,ill have to see which models it can do
