Well guys i haven't had much help lately trying to fix my car....but i am having a problem. Basically my setup is as follows T78 with 1300 sec. and 550 pri. . My problem is that as the car is about to go into boost the car bucks really bad...and then the boost comes in nice and smooth. Its hard to tell what it is....i mean i finally get the turbo into its spooling rpm range and then i bring the PSI to 0 psi and the car bucks and then hits 7 psi with no problem...its mainly that the transition from NA to boost is really jumpy...does anyone have any suggestions?
Thanks in advance...peace out

 

what EMS are you using? PowerFC? Haltech?

Sounds to me like your transition to the secondary injectors isn't set up right.

 

if you're using the power fc the driver for the 1300cc injectors is most likely mulfunctioning.

 

hmm i am using the power fc...how would i go about setting up the secondary injecters, through the commander or do i need a datalogit

 

You haven't set them up? Well, no wonder it runs poorly

You can use the commander to set the Secondary Fuel injector to 1300. It probably is set at 850 now.

 

wow! you just installed the pfc and injectors and went out and boosted to 7psi with no tunning?

 

take the gd out of your name.

The good (read:lucky) thing is that he was probably running really rich.

 

hahah no guys i am not that dumb....my commander has been tuned and is set up with my 1300 cc secondaries....i thought you were talking about mapping fuel specifically for the secondaries....well the car still runs like ****...and i have yet to figure out the problem

 

any other ideas to smoothen out the boost transition
