"ecu reprogram" right?
Not "head and cam setup".
Not "which ECU I can afford".
Not "a cheap way to manage my engine".
Are you trying to sell me an stand alone? OK. The entire long block it fine for running to 8k. If I was unsure of that, I would ask about it. All I wanted to know was if anyone knew somewhere where I can have my ECU reprogrammed. I know I have heared of some place. I'll post it for everyone's info if I can find it.

Perhaps you did no understand the first three times we told you.

our ECU can not be reprogrammed. Period. They have to be modified and a daughter board installed so they can be. And then the USER can not change willy neely any settings on it.

If you are talking about increasing the rev limit only. No. It was tried but it did not work on half the ecu tested. On the other half it did but then the guy pulled the mod as 50% failure rate is never good.

As for me selling you a standalone. Nope. One the tec3 I had I sold it to a lexus owner so no more standalone for sale :)

In case you were wondering ;)

I'm really curious as to why we can't figure out which chip is the ROM, desolder it, solder in a ZIF socket, and go to town on this?

once again, the daughter board is an option but its probably just as expensive to do that as it is to buy a standalone system. That is if it even works..

but whatever prove us wrong by geting it and making it work.

Maybe it would be better put this way...

It's a computer. It *CAN* be reprogrammed. The more reasoning question, though, would be 'why?'

The MAFT-Pro, with timing control, will do the same thing, and (unless you already have the equipment) be about the same price.

Besides, there is no easy-to-use GUI for reprogramming the Toyota's data, which means you will be going through assembly and hex code, in order to find what might be a 'table' and have to edit it manually, trying to figure out what exactly it does... you don't want to do that, trust me - unless you are extremely dedicated and/or bored ;)

No way. sounds complicated. I don't mind computers but thats a bit too much for me.
I'm curious about the tech3 and it might be a good option considering I can get the ignition upgrade with it. I think the AEM is pretty easy though, and I already made a coil-over-plug set up that works well already. what other options should I check out? I know of these two and microtech. Any others? the MAF translator has been good to me but I need to change that redline.

It is to my understanding that Techom/technosquare IS Geforce... A company I used to work for Put G-force out of buisness years ago in a lawsuit and then they became Technosqaure Im Fairly local to them and I know a few places that work with them and At this point I have only heard good thing about them.

You worked for Stillen? Actually, they merged with UPRD before becoming Technosquare. Technosquare is G-force and HMR America.

I know the techtom/g-force guys personally, and the techtom ecu works great. I would recommend it. I had one in my 91 turbo and will probably get one again if I decide to keep the 7m in there. They can remove or change any aspect of the ecu. I had the rev limit upped, fuel cut removed, timing changed, etc.

The techtom computer is a small daughter board that is put in place of the stock rom. The stock rom is then placed on the daughterboard and then another rom is programmed it alter the stock program.

The ROM is most likely integrated into the CPU. Dr J site has info on making a daughter board, but without a disassembler / compiler this will be a nightmare project.

no

Toyota actually instead of using ONE roms uses TWO.. Yes TWO roms.

Do you guys think you are the first to think of this... (you guys HAD to make me break out my reasearch links on this)
