Hey,

I just have a quick question...

I bought my power FC and planned to pick up more mods (mp, injectors, ect) and install them all at the same time, to save myself from having to tune the PFC twice. However, my car has a horrible case of the 3k RPM hesitation. What i want to know is if my current mods are not too much for the stock PFC maps to handle. It seems that the best fix for the 3k problem is to replace your ECU, so i want to install it. I really dont want to blow my new motor. my mods:

Pettit intake
Pettit downpipe
PFS catback
PFS stock mount intercooler
Vac hose job

Thanks for your help.

 

The stock PFC programming Should handle your limited mods OK as is.

Since you are so concerned, does that imply that you currently are not running the stock ECU with your currrent mods? But then modded Mazda ecus usually do not have the 3K stumble.

 

I ran my FD with an Out of the Box Map for a while. No ill effects. Just watch out for boost spikes with a midpipe. I had every bolt on mod.

 

Install the PowerFC and say bye bye to the 3k hesitation. It's so nice when it's gone that I forgot I used to experience it. I had a re-mapped Pettit ECU.

 

Yeah ill install it this weekend. I wish all this damn snow would go away so my 7 can come out of hibernaion! Thanks for the responces.
