i have an intake, dp, mp,cb and pettit racing ECU.
the car is boosting about 14-15 psi. i think it's doing that because of the ECU (it was set to give 14 psi on primary and 10 on secondary) and now i get 14 all the way to red line because of the non-sequential setup.
should i buy a profect B? will i be able to lower the boost to 10 or 8 for daily driving? and is the wiring going to be hard because of my non-sequential setup?
thanks
ps. the car felt good with 15 psi

 

i'm not sure if the car is running lean, because it still throwes fire when i shift. i'm not sure if thats an indication of running rich, help

 

I dont know much about the Pettit ECU but you might want to get it re tuned or find another ECU. 14 psi can be ok at times but its not that safe.

 

come on guys i know you can help.

 

I have the same mods but a PFC instead of Pettit. If I were you I wouldnt even go over 12psi without an aftermarket intercooler.

i don't want to go over 15 psi. i have no choise, the pettit ECU does that. it also runs richer than stock. i know that if i put the stock back i'll run 10 psi but i might run lean with all of my other mods

 

Get a Super AFC and AVCR at rx7store.

 

Couldn't he just do a "Home Depot" boost controller? Or am I forgetting something?

 

yes he could but i have a feeling he dosent know what a home depot boost controler is.

 

I'm running Pettit's ECU and have a Home Depot type of mechanical boost control which allows me to do a wannabe non-sequetial and set the PSI to 12 or 14 depending on my mood.

The limit is 1 bar and even though Pettit says that's 14.7. But when I use the conversion calculator is equals 14.5, so trying not to push 100% on the injectors and fuel pump I don't go over 14lbs.

 

i know about the home depot boost controller, but i've heard that they tend to give more boost sometimes, just like a manual boost controller. will the profec B work ? i did the poor mans conversion, didn't pull the turbo's out or anything else.
i also have an Super AFC (off my old car), should i plug it in, i thought that the pettit computer is already maxing out the injectors?

 

You just need to adjust the size of your wastegate pill or use valves to accomplish the same thing. No need to buy electronics or make any big changes.
