My mods are in my signature.

Crusing along is fine but when I press the throttle so that the seocndary plates open, as soon as my secondary injectors come on, I bog horribly and I can smell raw gas. And as soon as I let off I et a nice big "POW" from the tail pipe!

Free reving it does fine. Any thoughts?

 

start car
disconnect TPS
then try it again

 

^^^Didn't make a difference. And the TPS is set to spec.

Also it only does it when under boost. ANY boost. as soon as the secondary injectors are on and I get anything pressure more than a vacuum it bogs, crackles and junk. I boost fine up until 3500 RPM.

 

in your sig it says your running the rtek 1.5??? thats not designed for 780 cc injectors, that means your gonna run way too rich when they do kick on

 

rtek 1.5 uses the stock 550 secondarys

1.7 is hte one that uses 720cc

ic u have a safc? is your fuel tuned correctly? or has this allways been a problem?

 

No it's not tuned. It's never been a problem like this though. This just started a couple days ago.

 

Anybody else have some ideas?

 

Welcome to the wonderful world of piggy back tuning

Standalone will fix all.

there's not much you can do with that setup to smooth the injector's transition. If the R-Tek were designed for that size of injector it wouldn't be as much of a problem. But thats should help a little.....(matching your computer to what you're actually running).......however it'll run altogether better with a standalone

Edit: and what condition are the injectors in? New? Used? Whats the resistance across their coil?

 

Supposedly the secondaries are 780.

The problem isn't the SAFC or the Rtek chip. I've had both of those in the car for about three months and the injectors were in the car when I bought it.

This just started happening literaly last moday.
