You sure thats a 3.11 fdr with needing to run the 1-2 so quick?

Btw you can make a cheap inverter with a dbl throw 5 pin relay and control it with yer pcm fer now.

what car and year and motor is that 80e and the converter from again?

I have bigger tires in the back and at 2600rpm cruising slow speed, no load on the rear engine it is 2200 on the front engine.
So that calculates closer to 3.48 than 3.11

yeah that coulda been a y or a 9.

the y is the tq motor and will have a tighter converter that youll want

Ok we were able to do full throttle 1-2 shift with full staging and it is sensational so far. A real rocket. We had rain and it's still wet but no standing water. Even then the car runs 330 feet at 95 mph like a high 9 second car in the wet ! Unreal... 95 mph is just a few seconds.

Call me stupid for trying it anyways but after testing the Magnashift box I was surprised at how hard it pulled in the those conditions without feeling dangerous.

The magnashift box works well but I'm not conviced about the toggle switch shifting for manual mode as it's dangerous to downshift by mistake in the heat of the action.
The auto RPM shift mode didn't work because the RPM signal reads really dirty and all over the place. I will talk with the guys at magnashift for a better location.
I used the same signal that my AEM wideband failsafe gauge uses with success.

From a roll the car goes 40 mph to 95 mph GPS in 1.9 seconds !

BTW I upped the boost on both engines at the track last time but I broke the rear trans 5 feet from the line. Which is why I couldn't get the 9s I wanted.
So now I left the boost the same but so far the trans is taking it. At least 10 runs today.
