Hondata

I had this issue years ago. It came about when I swapped in k24a2 into ep3. I change out the k24a2 RBB vtc solenoid for a PNC solenoid & the problem went away. Although it seemed to run fine I didn't like "jittery" datalogs

we got the car running today - We (Synaspe Motorsport & Shea Racing) want to thank Everyone @ Hondata for their help

thanks for the help - Morgan spoke with Doug a few minutes ago

I am having a similar issue with a customers car. its a FD2 rce car purchased from HPD... we have only today to tune the car for a double header @ Mosport (world challenge) race this weekend.

we only have the usdm flash-pro & the car is set up with push-button start & no key. we tried changing the ...

bump - still looking for a definitive answer on running the '06 intake cam on a '04 tsx motor... hondata was never real clear on what motor you can safely advance to 45 vtc. the 06 motors have deeper valve reliefs in the pistons...

sooo once again does anyone know what kind of advance we can run on ...

what throttle body are you using? have you looked at a datalog to make sure the TPS is reading properly?

I was trying to help a friend out that has a k20z1 with 11.7 wiseco's & the same BluePrint Stage 2 cams & the motor runs VERY lean right at 2500 rpm (wot)! I added a ton of fuel but it still spikes to 14.5+ afr :shock: (was over 15.5)... the motor was asking for more fuel @ 2500 than anywhere on the ...

cool thank you for the info

thanks - I guess I might try 40vtc. I do plan on replacing the springs/retainers/seats with new '06 oem parts (actually outer RSX springs/ret with s2k seats I believe)

I have a fixed/adj intake cam gear (skunk2) I will try to check clearance of 45 or so with the valvecover off & see if there are ...

I have a '04 TSX swap in a ep3 & just acquired a 2006 tsx intake cam. How much clearance do I have? I was thinking of running 40 vtc max but I am not sure.

Hondata says a max of 40 or 45 vtc but I believe thats on a stock '04-'05 motor.

does anyone have any experience?

any news? I know someone else having the same exact issue with a k24a2. are you 100% sure you have a 02-04 engine harness? see if you can locate the sticker that has the part # on it somewhere on the harness

ok - problem solved! I decided to swap a used type R k20a "PNC" vtc solenoid into my k24a2 (w/ep3 harness) & the "jitter" is gone.

I am happy.

I have attached the datalogs (vtc set at 15 on full load). please forgive me for the partial tune you see. Should be street & dyno tuned week - I wanted ...

doesn't K-pro have a Countershaft driven speed sensor option? is the signal able to travel thru a 02-04 harness? if you wire 5v power say pin e5... of course I would only suggest this to someone thats a wiring expert.

I am not sure of what problems this can create - obviously doing anything of the ...

wow you have been busy.. I thank you for all the fuel compensation tables. I have notice my k24a2 running very lean on cold starts (32 deg + IAT's of 40 deg) less than 40 minutes later I was running very rich with IAT's of 110 (heatsoaked intake in an EP3)

I assume the water temp fuel comp is set ...
