Title: noob looking for help bde turbo conversion Post by: Mimjed on May 08, 2024, 11:27:37 PM Hi all,
I am a complete noob and can only apologise for this. I have been looking at buying a bde 2.8 4 mo with a turbo conversion done by stealth. Upon test drive it is down on power and feels like power is on/off/on/off during a pull. from vcds i can see that injector on cylinder 3 is running approx half the voltage of the other 5 injectors, they are deka 630cc - i've heard these are not great, but have no facts to base this upon. also the car has a manual boost controller, which i am led to believe is also not a good thing. it is locked in position and current owner (5 years) says he does not touch this. Is anyone able to offer any assistance with diagnostics/reading of logs? I have installed ME7 logger v1.20 and setup ecu with orig file, but wont know if it is working until i see the car tonight. I do have vcds so can log from there if this is acceptable. what would you recommend i log on ME7? sorry for the noob questions. without having a car/access to it, it is difficult to learn. cheers Jim Title: Re: noob looking for help bde turbo conversion Post by: _nameless on May 09, 2024, 06:43:02 AM Hi all, You need to vet the hardware to confirm there is not an issue with anything. You messaged me and said it has a misfire on cylinder 5, if you have a fueling issue like a plugged injector, continuously beating it will result in a melted piston. Use vehical for data logging you need a j2534 cable that supports k line. My personal advice would be not to buy the car, specially if you know very little about petrol engines.I am a complete noob and can only apologise for this.

Just low voltage to injector 3. Have only had a 5 mins test drive and a quick look on vcds.
No fault codes were present, but no idea what had been turned off on the ECU to be fair. Going back for a look tonight, hopefully figure some more out. But any advice on what to log would be helpful.

Threw faults codes for misfires, and misfires on 2 cylinders. Appears to just be coil packs dieing.

I don't think you have a clue what you're talking about. The injectors on these ECU's are all fed by the same ECU relay and ground triggered, there can not be any "voltage difference" on them. |
