So who wants their ECU's "Chromed"?

Got that already!

Forest sounds like a great candidate for testing.

I loves some beta roms

I'm talking about the Greddy map sensor.

yep, I'm on the same page. I guess it will only take a evoscan change to make it work. What's the best pin to use?

I would be interested if this could be made to work because I definitely know my hotwired Aeromotive Stealth pump is overruning but I do have a E85 upgraded line, filter, rail, and fpr planned in the future so I could make do for now.

Yes. I'll get that to you this weekend if I can ever make it back to my computer.

Oh and the best solution to FPR over run is to rewire the pump so that the resistor switch is still in place. The old school.boost a pump also is another great solution.

To be honest, closed loop does a pretty good job with tuning out the rich idle from over run though.

Yeah where is it at, I should be getting my evo maf in like a hour and it will be going in today.

So... What do you guys change in the tune to get rid of CELs on a 1G with no EGR/etc.

I changed everything I thought I needed to change in addition to disabling closed loop and the car didn't idle once the coolant got warm. Changed to the stock 99 tune and runs great except I got CELs and I still want to disable closed loop. Wonder where I went wrong...

I'm running the second to the latest version of his rom, as well.

a screenshot of the correct periphery settings was posted a few pages back.
