looks to be a solder in ecu upgrade, that looks like a few people got working in mr2's and a few 7mgte's along with a 2jz..

i liked the read in the second link, raise the rev limitor from 50rpm to 9000rpm -/+
remove fuel cut, or raise it, alter fuel tables, ignition tables, load maps, it's like making the stock ecu a stand alone!

only problem is, looks like it's the cost of a stand alone, i cant fiind that info lol.

but i know the rom boards will probaly run 300, and the hardware/software to access and log will probaly push 600,




the only reason i have stumbled across this is because im looking to increase the stock rev limitor,

this sounds like the smartest was, but i would need to sell off my maft pro to afford it lol, any ways,
i remeber seeing a post in either supra forums or here, and it was regarding how some one replaced a clock crystal in the ecu and was able to adjust the clock like 5% in one direction to get the ecu to rev out around 7500,

well any thoughts or opinions?
thanks for any help guys!

The crystal mod is not always guaranteed to make any results, you may actually lower the rev limit. I can't remember the person that does the mod, but I think he's in canada?

the crystal mod iirc only worked on 87-88 ecu's. as for the techtom, reg has had it forever, its too exspensive for what it is. look how cheap the hondata is by comparison. if they would release the software so you could tune it yourself after changes it wouldnt be so bad, but he wants you to send the chip to him to be modded. forget that. just get a ms2. itll do more for less money.

well thats partly why im searching for the crystal mod, i have an 87-88 and would love to be able the use 272's and shimless buckets to their fullest advantage. maybe 10k?:evil2:

either way i think im going all out and will evently just make this strictly a race car.

well, my interest in the techtom was soly because ive heard sevral times the tock ecu's cant be flashed, and reading those pages tought me some thing, they may not be flkahsed, but can be re-routed to differen't memory! lol

and every thing was a vaule as well, chould easy make the car hit fuel cut at 2 grand so when some one is parking your car for you they cant hot rod her.

go stand alone, ive been down the path your are currently treading and its an iron plated bitch. piggybacks or if you can find an aftermarket ecu would be the best bet.

welcome to 1992?

exactly.

the techtom was some good stuff back then....but there are a myriad of issues w/it.

1. you're relying on someone to tune it for you....w/o having your car there. you explain your mods, they burn a chip that they think will suffice. not the best idea.
2. cost.
3. availability- last time i checked, there weren't any more ROM boards available...making it impossible to do.

if you're looking to spend that kind of $$, then spend a touch more and go standalone.

errrrrr im such a sucker... so no one wants to see me crack open my extra ecu and mess it up uh?

my brother has done extent research on quit a few of the after market ecu's. , i think we both cam to realize for our power goals we could do it cheaper then going full standalone, but i guess i loose a few features i really wanted..

i guess there's no lieing, i will have a full standalone in my car probaly in a year. but till then i need to get tunning with the pro nailed down and the engine hummin again!

eh, not sure what's so hard about the "crystal mod"....just do it. used ECUs are cheap.

well i cant find any info on it yet, the last thread i read that was usefull about it sent me to a guy who used to mod them who wont do it any more since it failed so many times on 89+ ecu's, i have them yellow plugs and ecu's are way cheap! which makes me even more interested in tring the mod, i also have an n/a ecu or two and with the maft pro i could wire it into those and use n/a harness and get away with it aswell,

i have a friend that works at the shack so figuring out some of that crystal sizin might be easier,
i also have my ase electical cert, so soldering an ecu isn't to scary for me.

na ecu wont be able to handle as large of injectors as large as a turbo ecu. the afm on a n/a doesnt work the same as on a turbo and isnt relied upon the same way as on a turbo ecu. your better off sticking wit hthe turbo ecu.

~~~MoDs~~~~
full 3inch w/cat soon test pipe meganR GT turbo muffler~2 peice, 2.5" hard pipes~maft pro-speed density~lc-1 wide band~walbro~255lph~3.93 lsd swap~auto~awaiting 5spd swap~arp's w/ titian 1.4mm mhg~85ft/lbs~stock ct-26--13psi~hallman mbc w/ cab cable



with that set up i should be able to run map based and scale injectors... so long as the n/a injectors are the same as the turbo but just smaller im good.
i belive they have got the n/a afm signal figured out on the maft pro to get the speed density to work correcty iirc..

i guess my signatue stop showing it's self..
