I have the issue figured out. I thought I should post the fix to hopefully help others down the road. Long story short, I had the car dyno tuned and there was a number of odd issues after that. IACV problems, idle misfires, off idle stumbles, no closed loop operation, etc etc. Just a bunch of odd pr...

Thanks for the reply. If I close off the throttle plate completely, it will maintain 1500 RPM or so while warm. That being said, when using an IACV, should the butterfly be completely closed? Other platforms I have used usually want the butterfly to be slightly open so the IACV is partially working ...

Hi again, I had my K24 tuned recently and we couldn't improve the extremely low cold idle RPM without an IACV, so I added this on: https://kmiata.com/products/idle-air-control-valve-remote-block Trouble is, with this on, warm idle is about 1800 and doesn't budge. I have the TPS calibrated at 0% (act...

Quick update, a OEM TPS fixed my issue.

I'll do that and I'll check WOT voltage tonight and report back. Thank you.

That was my first try. It seems having the voltage lower at idle (I had it at .425V or so) it didn't seem like like it very well and it didn't fix the issue. I had a weird part throttle/cruise misfire or hesitation. Could be unrelated, but it seems to like .45V better. Is it OK to have less than .45...

CEL does go on when the pedal is fully depressed and I get a TPS voltage error. I'm considering getting an OEM sensor but they are all pretty old at this point.

My K24 uses a Skunk2 intake with a 74mm B-series throttle body using an adapter. The reasoning for using the B-series was to get away from the K series TPS which seem to fail often in road race cars. That being said, when I purchased a TPS, I made sure not to buy a cheap POS. But who knows, it's sti...

Thank you.

Hi! I'm a new Ktuner user and new to the Honda crowd in general so please excuse my ignorance. I'm running a 2008 TSX engine with a 03-05 Accord RAD ECU and Hybrid Racing conversion harness connected to an 03-06 Element engine harness. The only engine mods are 50 degree VTC gear, Skunk2 intake and c...
