And no, I don't have photos yet.

All switches are under my right hand this way. Switch from Normal to Race, switch from Race-4-button to Race-fully-automatic, clear Shift_Fast, upshift Shift_Fast, engage torque converter clutch, Indicator LEDs for the solenoids, and some other fun stuff. Nitrous cuts on shifts, for instance...

Sorry your panel isn't working out like you planned. "It's always something".

Persevere - yu'll get thar....

Yeah, oh well. It did work out like I planned, but complications always arise, you're right. I think a much simpler setup using a box will work out MUCH better, because that way I can troubleshoot easier and simplify the setup.

BOX IT IS!

Find the FSM and have fun

We have VB upgrades, and this and that to increase line pressure, but nothing to control shifts. The "E-shift" in our cars won't let you keep it in 1st... FTL!

Just finished a couple of changes in my shift-fast setup. I swapped in a 2002 ECU on my 3.5 swap and now I have no connection between the ECU and TCU because they are totally incompatible. So I now have to shift manually or by using the auto shift-fast. So I thought I had it all working fine until I took a ride on the freeway and found that 4th gear wasn't there.

I remember that no one had any luck with wiring up 4th gear and having it work so I thought I was in for a bit of a chore. However it was very easy and only required connecting the A solenoid to 12v. So its 12v to A and B for first. Remove A for second, remove A and B fofr 3rd and connect A for 4th.

Off the track tomorrow to try it out.

Perhaps with the 2002 ECU/TCU, but not with the A32 stuff. I tried just A, it will not engage 4th gear. I confirmed it with a voltage tester and everything. A is definitely involved, the LEDs on my switch panel confirmed that, but so are other things (overrun clutch?), as well.

Good luck. Low 12's?

It feels fast but hard to compare since its been 6 months since I had the other setup.

KRRZ350 the vct's were always there just not connected to anything. Actually I have a new engine, I sold the old one and installed it in a 2001 Max because I was thinking of going to a different platform. However I decided that the devil you know is probably best to stick with so I had to buy another engine, cams etc for this one.

Just finished getting the wiring finished for the A33 ECU and it was a fun job. Luckily I had eng92 to guide me along.

whoa, glad I asked, what were you doing previously for the camshaft position sensor? TIA

Most people who have done the 3.5 swap have opted to keep the 4th Gen ECU and swap all the timing gear and sensors so the camshaft position sensor was part of that. However I am now using the 5.5 Gen ECU and the complete stock wiring and sensors from the 5.5 Gen.

Jime, I think he means last season when you WEREN'T running the A33B ECU. In that case, KRRZ, I'm guessing he was running the same sort of setup most people run, since it was a different motor as he posted above.

And KRRZ, check your PMs, man

Exactly, for a second there you made it sound like you retained all 3.5 chains etc w/a32 ecu, that's why I was wondering what you did for the cam ps

For those who want to get your tranny to shift to 4th using the shift-fast mod the trans lever has to be in D not in 1st. However the shifts from 1-2-3 won't all work in D and since I never use 4th at the track I just manually shift to D on the highway to get 4th gear to operate using the switches.

I like having the overrun clutch disengaged when leaving the shifter in D. I now shift manually all the time on the street and I like not having the overrun slow the car down. So its in D for normal driving so I can have 4th gear and 1st for the track where I only use the first 3.
