Greetings. This is my first post to the MS forum and wanted to say hey. I recently build and installed a Camden supercharger in my 1987 Toyota 4runner. Details can be seen on my build thred http://board.marlincrawler.com/index.php?topic=96772.0
I currently have things running with the factory ECU only having upgraded from 195cc to 255cc low impedance injectors. It runs ok and makes it a great driver, but you can tell it has more and the factory ECU at times has a hard time keeping up, as well as having a rich idle, at 13-13.5 AFR.(plx AFR gauge with heated wide band O2) I am thinking of going with the MSPNP2-T8590 which I have read all about, but wanted to see if anyone has experience with a similar setup? I would of course be removing the AFM. I also spent some time looking at the SDS setup, but this seems a much cheaper and equally reliable way to go. That and I like the open sourceness of it.
Though I have built and worked on many vehicles over the years this will be my first tuning. How difficult is this? Will I see much improvement?
I have seen the MS doesn't use the cold start injector, is this an ok place to install the IAT? Any other information on boost 22re's or the best way to go about it would be great. Thanks Jason
New and starting project.

Re: New and starting project.
What kind of boost are you running?
Have you adjusted your AFM yet? Drilled the idle adjustment? spring tension?
There is alot of tuning ability on the stock ECU, I have a 94 truck 22RE EFI. I installed a Supra sized AFM on it to compliment the entire body of mods I have on the 84 model 22RE. The only odd issue is cold starts when just warmed up(but I hear this is common and there is a sensor replacement to fix).
As far as applying the MS ECU to your 22RE. Install the IAT in the filter housing, no heat soak that way. Stock is located in the AFM. Coolant sensor, replace the stock one or mod your MS install to use stock. Locations of your sensors make a HUGE difference in your tuning.
Speaking of tuning, plan on a 'Pro' dyno tune in your budget-find a local shop and talk with them. Then your learning curve will be much easier!
