Hondata

Hi everyone. I'm new to the world of hondata. I'll jump right into the issue:

Car starts and idles as normal. Up until this point had 0 issues. The afr was a little lean for idle, so while it was running I added a tiny bit of fuel on the low cam table, pressed upload, car immediately died. After it died, I started it again, tried to apply throttle and the car instantly dies. If it give it less than 5% throttle it'll rev up fine. The aem wideband reads normally, but when I am datalogging the AF doesn't change at all. It's stuck at 17.41:1. I tried erasing the ECU and uploading the original calibration with no luck. Car dies when throttle is applied. Still idles fine, a little leaner than normal. I suspect the ECU is getting the wrong AF reading and as such is not running right. I am worried I may have fried the ECU??? Sure hope not, I read on here that it's not harmful to upload while running.

Car is a 96 GSR built and turbo'd, running Hondata s300 V1. Everything else seems to be functioning normal except the hondata AF reading.

Help is much appreciated!!! Thanks.

Attached are 2 datalogs and the current calibration

close the program, reopen it, go to new calibration, open one of the base maps and see if that resolves the issue. You may just have a corrupt calibration.

Just tried that, ran a stock GSR calibration with 550cc injectors. It'll rev up normally now, but the AF reading still wont change between 17.38 and 17.41 on the hondata.

Somehow i got the afr to read properly.. changed the wideband input among other things. Not sure why it was off. But anyways, the throttle issue still persists. Whenever i give it more than 5%(assumed) throttle the engine bogs and dies. No idea whats going on here.

More specifically, when i punch the throttle it stalls out. If I gradually build up the revs slowly it will run properly, though fairly lean.

Post your calibration and a datalog showing the issue.
