Anyone happen to have a bin? 60-1 420cc stock afm

[matt85turbo]

I have been running jason's 420cc tune for 9k miles now but it does wierd things during light acceleration and it runs pig rich 10.0 flat under deceleration. If this this sounds like I messed something up with the maps/k value or something then let me know. I havent been able to get any noticable changes by changing values on the fuel map but I have only sat down with it a couple times.

set-up
60-1 with clipped stock exhaust side
fmic
420cc benz
gutted plenum
3" straight through turboback
No egr no idle/air control

cant help you with the bin, but why a 60-1 with a stock clipped exhaust wheel and a stock afm?

explain "weird things".

Under deceleration (or engine breaking with no throttle), the engine should go super lean. One of Nissan's way of fuel economy.

Your TPS may be set incorrectly or it may just be bad. With set incorrectly, you would have light throttle "weirdness" because the TPS would send a closed throttle signal at the wrong time. With it bad, you will never go into idle mode and your idle will suck because the computer will be still using the 02 sensor to adjust the mixture, making the idle ramp up and down.
