I've done the full throttle test for 5 sec in second gear and it doesnt come up then. If the ecu is reset before driving I can drive for hours and it doesn't come back up, I guess nothing new on PO, I got some info from honda-tech though which I am going to try here is some of it from a thread...see if it makes any sense to you!
Yeah, I'm pretty sure that's it.
Ha, I fixed it! It's an E-Manage only fix. Sorry I can't help you much.
Here's the equation one would need to duplicate this:
Take your EManage correction factor (Injector Change).
old / new = correction... in my case:
240cc / 355cc = .677
This is roughly how much air the E-Manage is going to pull out with an adjustment of 0. It's going to drop it to 67.7% of it's former air pressure to get the ECU to get back to the right injector duty cucle.
Now, take 1/correction to get how much air you need to add to get back to stock.
1/.677 = 1.48. You need 1.48x as much air pressure at idle to get it back to stock pressure. This is 48% more air.
Therefore the airflow adjustment should be 48% (I rounded to 50%). I made the correction at 0% and 3% throttle, at 0 RPM, and made the next increment of 100 RPM to be 0% (my normal setting).
Check the graphs out below. You can see before I start, the input and output of the Greddy MAP voltage is 2.83 volts. When I start it, and the RPM goes about 100 RPM, the voltages separate to be where they belong for the oversized injectors (.95 input, .75 output voltage).
