And here is the bin file, if you need it.

Hi Matt, sorry it took me a minute, but here is a log. Log starts from a standstill, and is just an easy drive up to 40ish mph easy through the gears. Lean spike/hesitation happens between 1-2 and 2-3 pretty consistently.

Hi Matt and OP, sorry to bring up this old thread, but I am currently dealing with a very similar issue where I have a lean spike/delay when shifting up between gears at moderate cruising speeds/loads. Issue sounds extremely similar to what OP describes. My problem seems to be timer related as well,...

The AlphaN increase fuel table is set at factory right now, I will increase this and see how it affects things. When copying the basic tables into the factory tune, I noticed you left out the Fuel throttle enrich (VE) table, and kept it stock...the original tune had this table modified in a few area...

is your 'Add fuel' table maxed out? I don't see this table in the address file... Would need to see a log of this if you can post one I will get one posted up here when I am able to get a log Yes, AFR is 14.7 at cruise in closed loop, drives like a champ! I was mainly just wondering if that latency...

Matt, I passed OBD2 emissions testing today, thanks to you and Nistune! Thank you so much for offering what nobody else in the world does: a tunable OBD2 KA24DE ECU. Without you, my goals of having a legitimately passing obd2 KA24DET would not have been possible. Smiles all around! That being said, ...

Matt, Thank you for the reply. The first log is a cold start, so the idle sits a bit high until the engine warms up a bit. I'm pretty sure this is normal? With that log, I mainly wanted to show what happens when the idle AFR during warmup goes from 13-ish (temp enrich for warmup), to 17-18. The chan...

Oh and here is the bin file currently on the ecu

Okay, so I recorded a few logs, and noticed some more odd behavior at idle. Log 1: On cold start, some weird stuff happens at around the 1 minute mark. I go from roughly 13:1 afrs to 17-18 for some reason. I don't see any map switching, so I don't know what is causing this drastic change. Log 2: Log...

Hi Matt, thanks for the reply. You are awesome for continuing support of your product over all these years. I'll check to see what the actual injection times are doing when I get home today. Consult view definitely shows both A/C switch and A/C relay turning on when they should, as well as Neutral s...

Also, I've noticed when trying to dial in my idle AFR's, a lot of posts suggest adjusting TTPMIN values. I don't see this table anywhere in the S14 KA24DE address file. Am I missing something? A couple other parameters I have come across that I can't find any info on: "Closed loop flag TP"...

1996 KA24DE ECU KA24DET Idle AFR is great with A/C off, but when I turn on the A/C, the RPM rises about 50-100RPM (normal), but the AFR's lean out to about 17-18. After a few seconds, AFR's seem to 'self-adjust' back towards 14.7, but when it gets to about 15, the AFR quickly spikes back up to about...
