After a lot of trials and errors, I found that my mistake was trying to set the short trim as close to zero during warm up. The tables that I modified were the cranking fuel tables and the cranking tables that are under coolant temperature compensation. These tables modify the fuel that remains atta...

So after a little more than a month, the problem hasn't come! I remember a similar situation I had with the vtec not engaging at the RPM's I tuned, and the issue was an electrical problem with the rear's turn signal. Because I don't like the idea of cutting my OEM harness to add turn signal bulb for...

I'm not 100% sure so, I'll check that and I'll let you know. Thank you!

Hi, I have a situation with my civic FA5 where the AFR goes crazy from time-to-time. This condition, generally appears after a pull. After I finish the pull and start cruising, the AFR start to become VERY rich (11.0:1 or lower). I've tried: S. Trims are +-5% before the problem appears The O2 sensor...

I've managed to get it even closer but the issue persist. The discrepancy is bigger with leaner readings but for this run, this was the leaner one. 1. 0:09-0:15: Wideband=1.01 and A/F= 1.00 2. 9:34-9:37: Wideband=1.06 and A/F=1.02 3. 11:09-11:14: Wideband=1.04 and A.F= 1.02 P.S.: I'm aware that is r...

Yes, I'm full aware of that. What I'm trying to say is that I'm using my wideband to ballpark the ECU lambda value. I put the example in order to Hondata able to see that I've compared the values, not only with one sensor but with various in order to confirm that the problem is not the sensor or the...

Hi, I've been doing a lot of tests in the o2 sensor parameters but still, the target is not reached consistently. I'm using a AEM Wideband connected to the ECU and using the same ground of the ECU. With the parameters not being change, the AEM Wideband reads 15.3:1 vs 14.7:1 (ECU), this means, the c...

Thank you!!

I'm having trouble with the datalog button. It works intermittently but lately I can't start the datalog. At first, It started the datalog by repeatedly pressing the button until it started working. Other times, I pressed the button harder, but now, is doing nothing.
