So...does anybody want to sell me their trimode TCU????
90-95 Q45 JWT Trimode TCU No longer Available?
90-95 Q45 JWT Trimode TCU No longer Available?
Well on the way up to the drag strip tonight I had 2 bad things happen. The first is a serious engine rpm miss under a heavy load (something new to me) and the other is that Ben Pila from JWT called me to tell me that they probably will not be making anymore of the trimode TCU's. The reason is that they use a special chip that only comes from Japan and no other chip will work. Well they don't have any more of these specail chips left and they don't think that they can get them any more as they might have stopped production of these chips in Japan and currently they do not know of any other replacements that will work for the trimode operation. They can still do the upgrade but it will be to only one mode which is the sporty mode with the 7,300 redline shift and you will not be able to switch back unless you install a whole new chip. They also demand for these chips is not high and that to order one or two more chips would not be cost effective. So if you are thinking about ordering a trimode TCU chip, please do so now so that JWT will have enough orders to make it worth their time and effort to locate these chips. They are in contact with their supplier in Japan, but right now things did not look good he told me.
So...does anybody want to sell me their trimode TCU????

We might have a solution to the no more JWT TCU as the LevelTen has also developed a computer program that will allow you to select 4 different things;
1. the shift points2. the firmness of the shifts3. 1st or 2nd gear start4. the amount of pedal depression needed to make the transmission downshift
Now that JWT TCU is most likely out of the question...I am going to seriously look into this. I have no idea how much it costs but but the JWT TCU costs $650 so I don't think that it will be much more than that. I was talking about a month ago with them on this and they said that it is very easy to operate to set all your parameters that you desire. This would essentially give me more freedom than the JWT TCU and I can program it to act just like the JWT TCU. I don't know if they have different modes...such as a trimode function as JWT did and I don't know if it will work with your regular transmission. This system somehow piggybacks off your current TCU....I think.

The LevelTen TCU will give you the ability to set the 4 items noted above and will do the shifting....I don't know if they have a dual program or not where you could switch to a sport mode while driving, but at least you could play around with the features more to your personal tastes and also keep the factory settings. I will call them tomorroow to find out all the details on what this system can do. I will probably get it after I make sure this 92 transmission will work in my car....as the way things have been going lately...I might just blow the engine tomorrow morning when I crank the beast

Well Why settle for only JWT... I searched up already but i don't have enought info but i know JUN and MINE's make a Ecu... yes JUN aaannnnndddddd MINE's. Both Companies are EXTREME... watch their vids... Minor adjustment and mods to thier cars and Mannnn, watch those cars go flying. I have a Vid of the Mine's Skyline if interested I'll Post.
Unfortunately I have not talked in depth with Sam at LevelTen regarding this option but I plan to by Thursday as this is when I find out what is wrong with my car and then I will know if the car is going to T3 for service. I can't wait till Thursday is over with as I will finally know the low down on my car and when I will be getting all my mods installed.
Well I have been searching for the past hour or so and the only thing I kept coming up with is a fully integrated TCU controller where you need a laptop to adjust all the transmission settings. Cost is about $1,000 but it allows you to do anything you want (I think) and then the program remains until you change it. Not really bad for $1,000 but I was hopig for something a little more easier to program & cheaper.
I did a long shot and posted my question to the BMW guys on another forum where they constantly mod their Bimmers and thought that maybe somebody over there has what we are looking for....but knowing some of those guys...I will probably get my thread bashed heavy....that is okay though as after I get my car put together they will not be bashing me too much more, well unless it is an M3 or M5.
Here is what I found so far....

I will definetly be calling Sam to find out more info on their system. I thought this would be an easier search..I guess not.

I did find a thread where somebody has this unit and they liked it but nothing more was mentioned. The software is amazing....graphs and anything else you could imainge diplayed on your PC...I bet Q45tech could have some fun with this hooked up to my car to map the optimal shift points based on my HP & torque curves. The trouble is that I don't have a lap top nor do I plan to buy one so that would be another $800 or so for an el cheapo laptop to go with this system. Hell I may as well manaully shift my new transmission and hold the rpms out there myself until 7,300 as this transmission should be bullet proof.
Well I spoke with Sam @ Level Ten and we our SOL. The TCU program that they have will not work for our cars. I am still searching and will be talking with two different sources. One is a dyno perfomance shop that for the right amount of money will map out the ECU & TCU to optimize all parameters and settings. I might have them look at the TCU as they said it would be around $800 bucks to do a full analysis and put a new program into the chip. Otherwise...I will just buy a used TCU and switch between the JWT TCU & OEM TCU when I need to buy unplugging it and so forth.
thats a good question...I am thinking that maybe my setup with all the mods would do better not redlining to 7,300 rpms since they only have one HP peak at 5,750 rpms vs. the 90-93's with 2 HP peaks at 5,500 & 6,000.
I am thinking that since I have to shift 2 times in the 1/4 that I might get better ET times redlining at 6,900 vs. 7,300 as I would think that more of the power I have is mid rpm range (4,000-6,000) versus the high end range (6,000-7,300). This is all speculative and I am sure Q45tech will set me pointed in the right direction, but I would rather run and additional 400 rpms in a stronger power band (4,000-6,000) versus 400 rpms outside of my strongest power band (6,900-7,300). It is like a trade off...if I have to shift...then I think that I would want to keep my rpms in the area where I produce the most HP & torque versus in an area where my HP & torque are not optimal.
So I would need to do a few ET runs with & without the JWT TCU to see if did me any good. This is all theory yet to be proven.
The trimode would have been perfect as I could not go wrong....I would still have the OEM settings and then the new settings.
As Q45tech pointed out...with the JWT ECU/TCU you would finish the 1/4 right at 7,300 rpms without that second shift saving a lot of time and producing the awesome ET...but if I have to shift then I would think that I would want to keep my rpms more in the strongest power band and I could do so by shifting at 6,900 rpms twice for a total of 800 rpms saved (400 from each shift) from 6,900 to 7,300. These 800 rpms might be better spent at the 4,000-6,000 rpm power band.
I just don't know...but these are my thoughts.
