Default Base tune? and other Q's

I'm using a MS in along with my stock ECU.

I have a '91 1.6L engine, 430cc black top supra injs, t25 turbo off a fwd sr20det @ 8psi, no intercooler. I will be using water injection very soon.

Does anyone have a base tune I can use for this?

My other question are how do I hook up my wideband to MS? I'm under the impression that I should have the wideband wired to my MS? I have never seen anything on this. I'm using a AEM UEGO wideband.

Last ones. Where is the best place to route a map hose from MS to the intake manifold? Where is the best place to plug the hose into?

Thanks ahead of time.

Answered in the build and install thread in the sticky on the top of this thread (super important threads). The white wire from the aem needs to hook up to the ms. It's the o2 wire on the ms, but if you're running in parallel you'll still be using the narrowband.

P51, you should write an entire detailed disclaimer, just in case .

Cookie Monster- in the megasquirt seciton, look for "Settings" inside the super important threads theres plenty of MSQs there. Also you can look in the diyautotune page base maps are everywhere. Most important you MUST tune specifically for your engine no map is plug and play, you will put your engine at serious risk if you chose to use someone's MSQ and not fine tune it.

Well ok, but I'm not running parallel so why should I care At least the rest of the stuff is at least 50% right, there IS a white wire somewhere.

8psi on the SR20 hairdryer and no intercooler is living on the edge of melting the engine all the time. I've seen those put out 280F at 8psi right from the compressor outlet. Is there a reason you don't have any intercooler at all? A fuel map for that will be so obnoxiously rich to try and keep detonation down that you'll soot and foul constantly with an intercooler.


There's a reason almost every turbo car comes with one, and the moment your water tank runs dry under boost, goodbye pistons.
