The Ultimate Product for Automatic Transmissions

[1SloColt]

I have been in touch with a local guy here that does a lot of local DSM work and tuning, and has done a good bit with the autos, about shifting modifications for us auto guys. He has a couple products in testing that will be a big help to us, hopefully. He gave me permission to post up the info, even though he's not ready for orders yet. He has 3 products he's testing right now.

Product #1 - Manual Shift Mode Conversion Box:

This box can be hidden anywhere and wires up to a few wires off the TCU. With the flip of a switch you will be able to switch from the auto slushbox mode to a FULL, 100% manual shift mode. This mode will change the shifter to a manual shifter, at which point L=1st gear, 2= 2Nd Gear, D=3rd Gear, and OD button + D = 4th gear. During manual mode, the shifts will be firm, with 100% line pressure. With the flip of a switch, you can go back to automatic mode. This is a foolproof setup, since the shifter is selecting the gear, there is no way to accidently switch between modes and cause a gear mismatch between the two modes and over-rev. If you switch modes, you'll simply be switching into the gear you're already in, or a safe gear as commanded by the TCU.

Product #2 - High mode shift modifier

This is a small box that can also be hidden and will be EXTREMELY simple to wire up. This box will operate transparently with the stock TCU to allow full line pressure shifts at high loads (i.e. WOT) This can be done one of two ways, either as a standalone unit, or through a simpler box that can be controlled through the ECU with special EPROM code offered in custom EPROM chips.

Product #3 - TCU EPROM upgrades

EPROM code changes for AWD TCU are currently in testing. So far shift points and shift pressures have been successfully modified. Socketing also available

He didn't really talk about pricing much, but he expects the entire package (all 3) to total around $450-500. Seems like a fair deal to me. Of course, he will provide them all independently as well, but obviously, all three would be pretty much the ultimate setup.

He has asked that people please be patient though. He's working non-stop on several projects right now that are taking up ALL of his time. Most everything is tested, but the final touches to transform from prototype to proffesional looking sellable piece, as well as writing up GOOD instructions for everything, is going to take some time. He's hoping to have everything ready to go by the end of the month at the LATEST.

Sounds great! Can you please go into further detail about TCU EPROM upgrades? What type of TCU is required? Will it work with 2G? Can I have a switch wired to select between stock and chiped mode???

FYI I am the local 1SloColt is Referring to

Not sure on the 2G TCUs. I will say that some extensive testing sunday was a success so far.

Got a car running on modified TCU code, running 2 shift maps, switchable via power/eco button. This was done on a chipped 3-plug TCU with a conversion harness to convert it to the two plug wire harness. Power mode now switches at 7500 RPM with full line pressure and Eco mode shifts at 7000 RPM with full line pressure. Oh, and it shifts normal pressure while cruising! We're going to probably play with the shifts at the track and get it fine tuned that way.. But even this is a huge improvement in feel of the car... feels MUCH stronger when it's using the extra RPM, even on the little 16G.

I'm waiting on a few parts for testing the other stuff, but it shouldn't be long. I have so many projects going on right now it's rediculous. Been in a mad rush to get my own car running in time to hit up the strip on the last day of the season. It's running a TCU-less Shiftronic setup with a auto upshift mode for Drag.. wiring nightmare!

Jeremy, Have you talked to Jon lately? Might need a 2G test-bed here soon. Plus, I want to talk circuitry with him.

You will need a EPROM TCU. You can pop it open and look and if you can recognize a EPROM ECU you'll recognize this. they use the same type of chip. To answer your question, yes, if you wanted, I could leave Eco mode stock and just modify power Mode.

I'm really interested in this as well. Please let us know if he has a tentative time line for a 2G setup available.

Very cool idea, I like the full pressure shifts at the customers given rpm limit with the Power button and whatever they want on the Economy button.

Definitely do one for the 2G TCU.

I need a reverse manual valve body with a Line Lock. Any ideas?

Reverse manual I can make a stock shifter do. You're on your own with the line lock though..

[420a-t]

Interested in a 2g version. So you can switch from using the standard tcu to this shift box? Or is pre-programed shift points via tcu-"tuning" and full line pressure on at WOT?

[GDNF2ET]

Here are pictures of an eprom and non-eprom TCU..My car is the one he worked on Sunday..Its a blast to drive..No issues at all..

[Car Cannibal]

What rpm did you program the shifts for and are they dead on with no delay?

How old is your tranny and have you had work done to it??

I have a feeling this TCU chip will be putting a lot of tranny shops on the hot seat about all our "issues" with sloppy shifts etc.

[GDNF2ET]

The trans shifts right where he programed it to shift at WOT, and thats at 7000 and 7500..You put the car in drive and forget about it...My car has the IPT restall and rebuild kit...., All you need is a socketed eprom TCU and a chip by HighPSI TSI Guy at the values you choose..

Do you happen to know if anything is in the works for 2Gs as far as TCU chipping?

If anyone has a 2G TCU that is EPROM I'd love to have a look at it to possibly do some R&D on it.

So far I've gotten a NT FWD TCU to work, that was the test TCU, was using it in an AWD, so that chip isn't really usable for anything. This was on GDNF2ET's car. With that combination I couldn't get it to shift high enough. We got ahold of the turbo AWD TCU and it worked perfect. This was done with a "3 plug" TCU. Right now I'm looking for a 2 plug TCU if anyone has one they want to loan for R&D. I'm pretty sure it will work the same but all the testing so far has been on the 3 plug, so I need to test on a 2 plug.

You need to 1st figure out if your TCU is an eprom or not..If it is, Dave (High psi) can socket it and go from there..If you get it socketed yourself, the chip that is removed must be saved intact, so he can use the tables on it to burn a new chip...

I'm going to pull my 95 AWD TCU and take pics of it and post them asap.

[GDNF2ET]

The 3rd row of numbers that start off with G1T1, will have an E at the end if it is an Eprom..The TCU pictured is a 90-92 awd, eprom...

I just checked my TCU in my 96 Eclipse GSX. It is an EPROM.

If you want to, I will send you my TCU for R&D under 2 conditions:

1. It has to be returned in working condition (obviously)
2. If you can get the programming to work for a 2g, program shift points of my choice before returning it to me.

No prob.. Hit me up in PM and we'll set something up.

[dsmmack]

I like this Eprom idea. Put what would be the stock power mode as the "economy" mode, and program the Power mode to be full line pressure and X000 rpm shifts.

Luckily enough the TCU I just bought this weekend for my auto conversion is in fact an EPROM unit. TCU harness and TCU for 50$ score!

Keep us updated with this TCU programing updates. I'm interested in this.
