Technosquare ECU Upgrade
I'm very interested in getting this upgrade, I spoke to the
Japanese fellow who did the programming and he sounds on the ball.
Who has performed this upgrade?
Feedback please.......
I WANT this mod....need feedback....

I don't plan on doing and additional binary programmimg.
Just want to get the eprom flash.
What gains are to be expected?
Has anyone else had this mod?
Were they pleased with it?
It is soposeto raise the redline to 7,100RPM and remap fuel+O2 over a broad spectrum.

I have the TS flashed ECU, and I am one of the testors. I know there were a few others who had this done after we tested.
The TS ECU can be tuned to your specifications, ie. mods you have. I don't know the gain in hard number since no one has dynoed ECU only, +15 HP and +10 TQ are only estimates. It does open the throttle all the way when you WOT, and car pulls harder from low RPM and doesn't taper off until near redline. The transmission is also more responsive; quicker up and down shifts (no modifications to transmission control module). The rev limiter is raised to 7100 RPM and speed limiter is removed.
If you plan to add more mods after, you either would need a reflash or one of the piggyback systems.

I'm the very first tester for TS, and I gained 17HP and 10TQ with just an intake installed..
he played alot with the timing on the engine to achive those numbers, I also kept sending it back and asking for more lol..

I'm talking about the data taken at the dyno.
IIRC I have some of your run files... I'll need to check them for that.
**EDIT just checked your runfiles, and you see 7030 MAX. Could it be the sampling rate of the dyno?

How do they know how the 'mod' affected this paramter? If all they change is A/F.. this can be done with an AFC, no down time, perhaps less $$$...
As for the transmission, it does have it's own ECU. But the flashed main ECU let the redundancy and value check be done by the trans ECU directly. If you want more accurate details, you'd have to call Tadashi.

Which run was that data taken from(7060)?
Mine must be then.. I only see 7060 and asked for 7200... Could be the dyno sampling rate, but even when I was stock at the same dyno, I'd see 6550.

After all is said and done, and i know u and Deus have prolly the highest rated ECUs here. How has the mileage been affected? I know after the ECU ur car dumps a lot more gas during the powerband. But how has it been since u got it done?
I drive my car at work, daily... LOTS, how would my mileage be affected?

i dont know if this question was asked before, and i know the answer is probably no, but lets say i get the tecnosquare reflash and i take my car for service, if they flash my ecu or disconnect my battery will that have any effect on the reprogram?

with fuel I can't give you a accurate answer since I drive on 22's, the wheels alone drop my mpg some, but RH told me that his car dropped alittle on it, not enough to complain about..

Am I reading this correctly that Tek-Niq gained 17HP with CAI and ECU combined? It would translate to less than 10 hp for ECU mod. I suspect that most of the gain is from having the throttle fully open at WOT, allowing more air, and leaning the very rich a/f mix.

so 29 total hp with this set up..

As far as MPG, maybe 10 miles less per tank average on stock wheels. With y-pipe, seems to be almost stock. I'll have to give it more time to know for sure since it's getting hot.

reason for the piggyback is cause I'm still alittle lean on the low end, thats where the 14.5 comes in, I wanna get it so right after 3K I get all the fuel so the low end is better, I wanna get the most out of these headers when i get them..
That tuning box, can you have different tunning presets? And how many?

Yes search..... but thats for a VQ35 from a 5.5gen, im not familiar enough with that car so I dont know if the ECU has the same pinout as the 6th gen. If it does.... Thanks for the help but picstures still tell 1000 times better story then a diagram.

Besides, pics of spliced and cut wires wouldn't do you any good anyway.
