So who wants their ECU's "Chromed"?

Thanks for the info, very helpful. That is crazy that the car's stock are basically setup to run flat 10s or even in the 9.x afr area, I knew they were rich, but I was thinking they were closer to 10.5:1.

Yep! How do you think I got 15 more HP at the wheels without touching boost?

Remind me tonight to show you a neat trick to tuning the Fuel tables.

would love to see your trick!

This explains why I had to pull sooo much fuel out of the top end when I was using the emanage to get to 11.5:1. It is no wonder these cars are pretty hard to blow up BPU.

Yup.

The car was almost 100% stock (high flow cat with Borla cat back, SSR lighter wheels).

Greg you must show me your secrets at UMG, also you have a place to crash yet? We have an opening in our room.

Back on topic, with emanage blue and 560's it worked out perfectly for me to tell it I had something like 590-600cc injectors, that made the idle perfect and wot at 11.3, just had to add fuel for under partial boost. Looking like I'm going to try something similar with the flash ecu, at 565cc injectors im idling pretty rich.

start with the latencies, they have the greatest effect on idle.

Are you using evo 560s? The known latencies in the evo world may not match up perfectly since their injector drivers may not be the same.

EVO 560's. You think so? I figured I would give it a shot to see if I can fix 2 problems with 1 change.

what are your current latencies, scaling, and fuel trims?

They match perfectly. It's the scaling that is different.

Some tweaking with the MAF tables will make your fuel table match closer to your WB.

staying with the WI guys. We got a pimp room this year.

I saw Brett bitched out.

ah that's awesome. Is our injector hardware basically the same?

Edit: I wish I had my evo 560s from years ago instead of these pte's.
