anyone else throwing codes during 5-6,000 RPMS in 4-5th gear at part throttle. It seems as it runs fine in 1-2 gear at part throttle but underload accelorating any at part throttle in 4-5 gear the ecu freaks out and throws a bunch of codes then goes into some mode that locks me out from reving above 6k. Once I clear the codes it runs fine again and allows me to rev to 9k.
Heres a video of part throttle throwing the code. Sorry the video quality is super crappy. I popped the phone in and I guess the mount was loose.

PS- I fixed the idle issue with the help of Rads friend. The harrness was still wired for a 04-05 and I had to disconnect the green/gray wire and connect the two yellow wires together. The car now Idles correctly and everything now but I still have this part throttle issue in the upper gears. Any help would be great.

Code P0122
for the purpose of helping someone in the future..
If you have the greddy harness and you plug everything in and the car runs like this...
https://vimeo.com/47027462
The issue may be due to the harness being configured for a 04-05 car and not a AP1. The green/gray wire is suppose to be disconnected when used on a AP1 car. Mine wasn't and was causing all kinds of idle issues. I "fixed" it by enabling the TPS map but over time it started messing up again.
green/gray wire was plugged in... Hmmm
unplug it and plug the two yellow wire together...
This fixed the idle issue and the P0122 code completely but I'm still dealing with the issue listed above. Rads friend (un-named) is helping me out alot and hopefully I can have this bad boy working correctly by sunday.

update on my Vtec lowering issue...
what needs to be wired up for Vtec lowering to work
Hmm, hello, where is PIN 21?
So basicly I need to cut this yellow wire and run a wire from PIN 21 to yellow wire pointed out on the blue connector. The other side of the yellow wire just gets caped off.
Rads friend is freaking awesome! We have had over 20 emails back and forth and has helped me alot. Still haven't got a email from Noel though. Wiring issue #2?
fighting to take out a pin though.

Me 2 bro, I'm about to PM you in a min. If I can manage to get this pin out I'll test it tomorrow and see if it works correctly without throwing codes. I'm super excited the car idles normal now. Shyt was crazy. I'm concerned about the .22V idle TPS reading though so I have another throttle body being mailed to me. The manual says it should be .45-.5V. According to what my cousin said the honda laptop told him, my OEM ECU at WOT is only thinking I'm at 89% throttle even though the throttle body is fully open. I'm not sure the effects of this but I'd imagine they arn't ideal.

Thread Starter
I ordered a new harness direct from Boomslang as a backup in case there is an issue (ie intermittent connections) with the one I have. They asked me via email after I ordered whether my engine was NA or FI. So I asked if they have made any changes based on feedback from PTuning and they said yes. The change has been in production for three months. The difference is below. Does this make sense relative to causing misfires as reported by PTuning? I also wonder if this harness change will make some difference to my existing tune? If was going to take baseline data with the existing harness to compare to the new one what parameters should I capture? LT and ST fuel trim of the OEM ECU? Any thoughts on this?
The Boomslang harness change based on PTuning findings.
FROM
MAP has input/output with FI apps.
TO
MAP only has an input to the Ultimate with NA.

Really would hate to invest more money in a POS harness. I'm already about $900 in on this "tunning solution" and don't even have a wideband or a real "tune."
