T-78 is here- need some help
It is going on next weekend what do I need to do to my Power FC so I dont blow up my car? Anyone want to send me a good base map to start off with till I can get it tuned. Please help

What type of fuel set up are you going to run? (Injectors, fuel pump, Regulator?)
|
I am only going to run 15psi until I can build the engine stronger.I have 1200cc secondaries and the 20B fuel pump,Do you think I need a bigger fuel pump to run 15psi? Do you have the power FC With a T-78, thanks

Im not sure how much fuel the 20B pump flows, but you will need to upgrade your injectors to the 1600cc ones. Go with the RP setup that comes with the fuel pressure reg, 2 1600cc injectors and fuel rail for $900. RX7.com(RP) will also be able to tell you what fuel pump to use or if the one you have is adaquate for the T78 since this is what Ari uses.
The Power FC will be able to run your T78 fine. You will need the optional boost controller selanoid to run over 17lbs of boost. SR Motorsports sells them and Ray will also tune it for the T78 for you. This will make things much nicer for you till you get to a dyno. Ernie |

I thought I would be safe with what I have to run 15psi but what about my base map? Ray charges like $80 an hour to remap it and I was wondering how different my map was from the T-78 map and if there was a base map for it. Thanks
|
Your base map is programmed for a cat back exhaust and a freeflow intake with the stock sequential turbos so its totally different then your T78 setup. I wouldn't drive it with this map at all. It sounds as if it may be worth paying Ray the $80 an hour if you don't have a dyno close by.
And Greg, thanks for the info.....I'll go that route when I get my single. Ernie |
Yea your probally right, there are probally 10-15 dynos in a hour and a half away but the power fc nobody is familiar with.Thanks for all the help
|
I would give XS a call based on their PFC tuning ability. I think Eric Hsu? works for them also. I would talk with Carcrazy as well. I agree that 1200s should be enough if you're going to run 15 psi.
Congrats on the purchase! |
what kind of whp will an rx7 have with 15 psi on the t78? can you run this setup without any modifications? (leave everything stock in the car?)
