Decided to ditch using a VR sensor for the crank wheel, and bought a new hall effect sensor that DIYAutoTune came out with. It's a really nice sensor, no VR conditioner to deal with, just a nice clean square wave signal... And I didn't have to change any wiring really, just pulled the lead from the ...

Wow, 17.5:1... That's pretty lean.
I think maybe I need to lean out my cruise a little now, I hover around 16:1.

Not getting any overheating issues on long highway cruises? Though I suppose you have a pretty beefy radiator to go with that big engine.

No kidding, no way you could pull that with a carb I'd bet.

What kind of AFR are you running on cruise?

If it were only that easy... Parts aren't easy to find to begin with, at least around here. lol I got a reman'd shaft on it's way, we'll see how long that one will last (or the other OE), worst case I have to get some custom stronger axles made up. Never thought I'd ever break an axle with a T25, I'...

Thanks MegaSquirt, you made me break an axle!

I've been thinking about doing this to my Dad's 96 SE Pathfinder, he's tired of the OEM fuel mileage and I know I could get better with Megasquirt and make more power at the same time! Probably not with a turbo though... 135 degrees IAT seems a little hot, even on my tiny T25 I rarely see over 115.....

Some more tuning work.


Much better now and safe.
I haven't seen any MAT over 120 deg F yet either, so the intercooler is doing it's job (it's about 95 out today).

I've attached my latest MSQ, for those interested.

http://i3.photobucket.com/albums/y59/seishuku/graph-6.png Latest WOT graph... DC and AFRs are much better now. It would seem that a combination of low fuel level and pressure set to 70PSI instead of 60PSI were the cause of my problems, though I was still maxing out my 450CC injectors. At least now ...

The reluctor wheel was made our WaterJet, custom job. But unfortunately I can't do any more of them, not with out it costing a lot of money. Same goes for the CAS disc, but that didn't really work out quite as well as I wanted, it seems the waterjet isn't quite as accurate as it needs to be for a sm...

Still need bigger injectors, 520CC/min isn't enough apparently. Still borderline, but safe for now.
