so i installed a greddy turbo kit on my fit and as i went for the first test drive around the block the cel came on and the car fuel cuts at around 3750 rpms. totally doesnt feel safe. i pulled a code and i got p2649. vtec solenoid high voltage. has any one had this problem when installing a turbo kit??? my car is an 07 and has 55k miles on it.

 

It has happened to a few cars but none I know of were on boost, turbo or otherwise.

 

ya i email greddy and they havent replied to me yet. but i hope it wasnt just a coincidence that that came on as soon as i turned on the car.

 

did you try re setting the ecu

 

If the Greddy tuning alters the vtec operation it could be related but like I said it has happened to cars on here due to the solenoid going bad and they were stock as far as I can remember.... I'm an old guy so I might not remember things right all of the time.

 

lol no your not old..... but ya i looked other threads and i saw that... but i was just checking if the piggy back caused any problems with it. cause i dont want to buy a solenoid for 150 ish and it not be the problem.


and i tried clearing the code with a scan tool. is that considered resetting the ecu???

 

I am sorry I had some beer on an empty stomach and took a nap... Just removing the positive cable from the battery for a minute or so and reconnecting should clear the code but if the problem still exist it will do the same thing.

 

so i unplugged my piggy back harness and plugged in my regular harness to ecu. and cleared the code. started the engine but didnt drive it. code did not turn on. i plugged the piggy back back in and code instantly turned on. so i think it has something to do with either the piggy back harness or the e manage. im sure greddy will get back to my email on monday.

 

get rid of the emanage and get an aem fi/c. so much easier to deal with and will save you in the long run.

 

I have one but haven't put it to use yet. I am going to upgrade my KWSC to 10 PSI with the kit that is offered by them and will need the FI/C for additional tuning needed after doing the methanol/water injection thing..... There are a few threads made last year about it's use on supercharged and turbocharged Fits.

 

Are you sure to remove the POSITIVE cable? I was always taught to remove the NEGATIVE cable first...

 

You were taught right and I shouldn't drink and post.

 

just don't want folks who don't know better to screw something up. lets start drinking!

 

I would love to if I hadn't already taken my medication..... I really shouldn't drink at all according to what my doctors say.... You go ahead and drink some for me and I will stay off of here if I have had a drink so I don't put out any bad info.
