Still thinkin 'eh Mudchild?

Defiantly going to put one on. I'm just doing some research before I get started. Like all the projects I do I like to have it all planed out before I even turn a wrench. I'm sure I'll be picking your brain along the way

Planning thourghly is always a good thing.

Does boost effect the modulator on the auto tranny in any way?

Yes, it does. While under boost, the trans will shift at the preset engine governor limit ( 6200 rpm for my 95 16 v auto) rather than using a vacuum signal. ON boost = no vacuum,  This can be changed by using an in-line vacuum bypass valve to the auto trans vacuum line.

So I'm thinking something like a 0.050" orifice from the vacuum source then a tee on the modulator, and a check valve to atmosphere on the branch of the tee to vent any boost pressure?

Or is there a purchasable part that will do the trick?

What did you and Wild do?

  I'm not sure what Wild did, he never mentioned it. Your idea sounds like it would work, and there is a one way vacuum valve that you can tee into the source, ( try NAPA or Auto zone) and it should only allow the trans to read vacuum. I haven't tried anything yet, just for lack of time. I pretty much just learned to drive around it by staying light on the skinny pedal unless I really needed the acceration. Got any pics of your setup?

I don't have any recent pics yet.  I'm in the middle of converting my 5 speed to an auto.  (What a major PITA!)  When she's complete I'll be sure to post. (Looking like 3 weeks or so).

My next big task is figuring out how I'm going to control the lockup with Megasquirt 1 v2.2 board MSNSE Code.

Yeah, that torque converter lock can be a love/hate deal for sure. I'm glad I have it working to lower rpm a bit at highway speeds, but at certain rpms/speeds it's always "hunting" going back and forth between in and out. Gets to be quite annoying, I'm thinking of running it thru a manual switch, turn it on only when I want it.

I tried a one way vacuum valve, didn't work.
The only problem I have had is under hard accel, if the tranny
drops to 1st from 2nd it goes into neutral until you back off the throttle.
I havent found a fix for this, but it hasent really been a problem.

Really you just need to blow off the boost to the trans, but still allow
it to see the vacuum at cruise, some messing around with one way
valves installed the right way should solve it, but just inline don't work

did you guys know that there is a company that i have contacted about making a turbo kit for the 8v trackers/sidekicks, www.505performance.com contact them at sales|removethispart|@505performance.com.  i asked them if they would build a kit because they have been building turbo kits for the jeep 4.0l for years, and they told me that if they had enough interest in the turbos, then they would build up a kit.  please e-mail them and let them know that you are interrested and hopefully they will keep up their end of the bargain, thanks guys
