I originally wanted a Braineack built MS DIYPNP but he won't respond to my PM's about it, I also sent another PM to another member here who builds them and again, no response. I'd like to get something ordered this week so I'll have enough time to install it and tune it before March when the season starts for me. My set-up will be a 91 car/harness, a 94-95 engine using the 94-95 TPS and IAC valve, 1zzfe COPs, and 460cc injectors.

I'm considering getting a DIYPNP and building that, along with the IAT sensor kit so I can delete the MAF. Do I also need to order the stepper IAC mod kit? I'd also probably get the sequential injection kit, for a total cost of $492. That price is without any stimulator that I feel I'd probably need as I have very limited experience soldering to PC boards.

The other option I'm considering is getting a pre-assembled MS2 with the PCB 3.57 which from my understanding already has the ability to control the IAC. Then I'd need the wiring harness and the IAT sensor still. The total cost for this is $528. I'm more confident in my ability to wire directly to the harness than I am of my ability to solder the PC board together. And this car will never be "returned to stock" so I'm not worried about hacking the harness up. I'm just wondering if there's anything else I'm missing that I should consider getting and am looking for opinions on what the better option would be for my set-up. Thanks

 

Sounds like you already made a choice

 

Yeah, I was definitely leaning more towards the MS2, I guess I'll go ahead and pull the trigger on it.
