i cant figure this out and its pissing me off! I have a turbo b16a2 in a ej1, it has the greddy 18G set up with RC 550s. Im running crome managment with a break in tune. Im running SRP 9:1 pistons and Eagle H-beam rods. The car idles fine a little bogging under acceleration but under WOT, around the time Vtec kicks in it studders and falls on its face. A N.A. LS could beat this car right now!!!

 

maybe its cause o your vtec engagement point. i know sometimes when its lowere too much it will sputter like it does not want to go. just an idea.

 

What's a break in tune?

Do me it sounds like the tune was shitty or on the wrong ecu.

Any CEL's?

x2....and wheres the vtec crossover point at?, do you have an upgraded fuel pump and fpr? probably not getting sufficient fueling, but an excellent tune is crucial when boosting an n/a vehicle.

 

Even with a turbo, messing the the vtec crossover is a bad idea.

 

One word: TUNE!

/thread

 

I dont think the tuner had that much experience, if the car is still being driven in the same fashion at this moment, might blow your engine or damage the engine period. Trailer it to a reputable tuner and get it fixed asap, so you can finally boost happy.

 

tuner is very good hes putting (last time i talked 2 him) 355whp and like 284 lf/lbs on a boosted ls vtec. Im running a crome p28 and yes we messed wit the vtec becuase it didnt feel like it was kickin in but it didnt change n e thing. We tried pulling timing way back- no change, we tried adding, pulling fuel same problem it sounds mechanical to me. Im running an AEM Fuel rail and FPR. The only other thing i could possiblly think of is POSSIBLY the timeing belt is a tooth off. But the car idles great so i kinda didnt think so.

side note- I took the car to king motorsports on tuesday and they really didnt wanna fix it because im not using hondata so they told me 2 come back and get it.

 

Take it to a different tuner, sounds like a **** tune.

If the car was mechanically fine prior to install and tune, then thats the problem there.
