Hi Stuart,
Been tracking this thread with interest since I drove one last year in Italy with Maserati. We corresponded at the time. I do have a burning question, as I noted from your original project posts on this thread, that you discovered that the original ECU was programmed to just dump fuel into the injectors, with no finessing or thought given to emissions, efficiency, tuning or anything else for that matter. You also said that the chaps that were helping you get a road legal mapping together, did save a dump of that original mapping somewhere. Sound like you now have it on a separate ECU unit?
My question is twofold,
I guess I'm trying to understand if the ECU is monitoring its inputs/outputs based on what it knows its doing, or if something else is doing that and would be heavily confused on a road car with all its sensors, due to the crazy emissions resulting from the race mapping?
- If I obtained another ECU unit, could your chappie (or someone with the right stuff) upload that race mapping to the new ECU?
- If I then dropped that ECU into my 2008 GTS, assuming of course, that I'm at a track day, how would the car perform? Would the ECU accept that its dumping huge fuel loads into the engine, and thus expect the emission readings from the (for example) lamda sensors to be mental, or would the engine management system just start throwing loads of errors on the dash, becasue the air/fuel/exhaust readings were way out of step?
If it DID throw loads of errors, could they be cancelled with an ODBC connector for a few laps of the track, before swapping out back to the standard ECU for the drive home?
See where I'm coming from? The theory of doing this intrugues me. Eg, being able to keep a track day engine mapping based on the GT4MC on a separate ECU unit. Or am I talking ****?
Cheers,
James
Hi James
I do still have the original Trofeo map but I don't believe that it would play ball on a road car. It would massively over-fuel and due to the safety measures on the road car, I would foresee an engine management light being thrown and the car going into limp mode before any damage is done. The lamdba sensors, the cats and air flow sensor would have a fit and be far from happy and none of these three components were present on the race car when the project started. They have all since been added and together with the firmware & ECU work, it now all works in harmony.
This ECU trickery is all a long way beyond me but from what I have learned over the the last 6 months, this is what I believe would be the case although this is probably more a question for Trev
I do know of another Trofeo car for sale right now in Switzerland however if you fancy doing what I have done? Here it is -
Cheers
