New ECU for Boom Peugeot 2 litre engine with auto gearbox
[QUOTE=tomg;751356]In the past I have added "sensor upgrades" and was instructed to disconnect the negative battery ground for about a minute and hopefully when reconnected and started it will read the airflow and reset it's self. Just a thought. Tomg[/QUOTE]
Great thought tomg. I've just phone the techs and asked the question. They said that had not done that, so I will try it myself. The techs advised they are sure it's a programming issue but a simple solution is always the best place to start! I've also been told that the ignition should be turned on for 10 seconds before starting, or it can upset the ECU. I had never done that. I'll try your solution first, cheers!

[QUOTE=Jack Klarich;751482]Randall, Welcome to Trike Talk
1 more question for you. When your techs checked your ECM did their scanner give them a VIN? Most good scanners will, this will help to narrow your search for a new ECM. Best of luck;) I am amazed with the amount of retarded ignition you are seeing[/QUOTE]
Hey Jack, I can't contact the first 2 techs at the moment to ask about the VIN. I have a VIN number from registration papers only. That VIN is apparently not compatible with Peugeot VINs in Australia (of course, why would it be?!!) The techs were also amazed (as I was too) about the amount of retarded timing. The 3rd tech could not even get his equipment to read. He is trying to source an after market unit with new wiring loom. He advised against spending the money an importing a replacement ECU from the manufacturers because it may not fix the problem if it happens to be something else. If he can source another programmable unit, with new wiring loom, which will talk to the gearbox ECU, I would be happy to go down that road, because a lot more workshops across the country will have the equipment to check and re-program should I need that done in the future.

Contacted techs and the VIN did not display. I only have the VIN off registration papers.

[QUOTE=Sidecarbill;751522]Well we never remapped anything, when a car had a problem we searched for the problem, not a work around. When a car doesn't run right and doesn't show codes it's usually a mechanical problem. Could be a break in the intake hose, a vacuum leak or a bad gasket. Put a smoke machine on it and check for leaks.[/QUOTE]
thanks and good call Sidecarbill, that's been done to no avail

[QUOTE=vwbug72501;751498][ATTACH=CONFIG]86826[/ATTACH][size=3]Rabbit Hole Alert!!!
[/SIZE]From my experience, moving into the area of remapping any ECU will lead you into an unbelievable myriad of intentionally vague and misleading information. [B]90% of which is false and just plain wrong!!![/B] You can start researching the remapping by first finding out what model of Peugeot runs that particular engine/trans combination. If it exists in a "performance" model or in a sedan/coupe that is ralleyed, drifted, etc. then you may be able to find a forum where they discuss these performance issues. There are also CANBUS forums out there that discuss modifications of the communication protocols used by the various controllers in vehicles.
This is a whole new world that [B]will[/B] make your brain hurt! It is not insurmountable. Unfortunately, most newer systems require keying to a VIN and that usually requires some kind of proprietary equipment to achieve this goal. In the USA, many are afraid of running afoul of the Environmental Protection Agency (EPA) and the associated liabilities and fines. In this environment there are a lot of snake oil salesmen ready to take advantage of the ill informed and uneducated so proceed cautiously and verify the facts as best you can before jumping in.
Good Luck and keep us updated.[/QUOTE]
Thanks Tom for the advice. I hear what you are saying and I'll take it on board. It's all out of my league and I take advice from those who know more. I came from the days of carbies, using a timing light, gapping my own plugs and tuning my own cars. Unfortunately those days are long gone!
