I gotta say.. That motor sounds amazing
I installed my new AEM wideband on Friday night, it definitely works much better than the LC-1 that I had, it also shows that my LC-1 was out of calibration too because the bit of tuning that I did do with it ended up being too rich according to the AEM. I leaned things out a bit and the car definitely felt more eager on the top end. Watch out Kamus because I'm gunning for 200whp out of my 2.8L M20

Bring it on buddy! Mark has already been in touch with me, just need to set up a date to flash me a new file. I have high hopes!

yea your car is running FAR too rich... the target lambda should be around 0.91-0.92, definitely no richer then 0.88.... turbo cars don't even need as much fuel as you're running

Update: Mark D provided a software update today, and the car has come even more alive in the 4000 to 6500 range! Sh!tloads of urgency and quite a bit more pull in all gears and everything feels and sounds a lot smoother too. Next step will be some wide-band measurements, then a final adjustment to the code if the measurements suggest one is needed. And finally I will return to DragonWerks for some more dyno runs for the verdict.

Also Id like to clarify something: in earlier posts I may have given the impression that Mark has tuned my car in the past. This is not the case, what I actually have is an off the shelf product from Metric Mechanic that Mark was involved in the development of. Mark has very graciously agreed to help further with getting the most out of the product in my particular car.
