What does this ECU upgrade do??

Ive seen it around but I havent really followed it. Who makes ECUs for the 3.5 and how much power gains are there? Is there a higher redline? Is it for both auto and manual trannies? Does a higher redline mean the engine wont last as long since its going through more pressure? How much is it?

you cant reprogram to you liking, there is no laptop or a controller attached to the ECU for you to make changes (basically what U get is what U get and each car is diff). I seriously think this mod is not going to work for *me* as I like tuning with S-AFCs and Emanages for less and have more controll. Thanx.

Technosquare. The gains are dependent on your current mods.

Is there a higher redline?
Yes. They upgrade it to 7100 from 6600 (auto) or 6900 (manual).

Is it for both auto and manual trannies?
Yes.

Does a higher redline mean the engine wont last as long since its going through more pressure?
As long as you don't keep the car at or near redline for more than a second, you should be ok.

How much is it?
$495 + $25 return shipping.

Or you could get the Limited Spec from Technosquare for $345. The L Spec:

- raises the rev limiter (up to 7100 rpm)
- eliminates the speed limiter
- remaps the drive by wire

No changes are made to timing or A/F ratios.

The full version does this:

If you get teh L-spec then I would suggest getting SAFC-II for on the dot max power A/F ratio. Its probably a little more expensive but its the best way to go.

I have the TS ECU (the whole shebang... I think they call it the f-spec or whatever)

Read this entire thread before you form an opinion.

Along with that information in that thread is some track info:

My best run to date is:
RT: +0.311
60': 2.230 (best)
330': 6.114
1/8ET: 9.309 (best)
1/8MPH: 76.25
1000': 11.987
1/4ET: 14.302 (best)
1/4MPH: 99.52 (close to best)

I usually shift when my tach says 7000rpm but according to many on here and my dynos the tach is off a bit. At 7000rpm on the tach I am actually at about 6700rpm. I should be revving out to 7400rpm and when I input my dyno numbers into shift point calculators they say I should be shifting at redline in every gear. In that case it may be possible for me to reduce times a bit more. That run was done on a track at 700ft elevation. I dont remember the atmospheric conditions. I have not been to the 1/4 strip since this last run. I have been to the 1/8mi a couple of times and have been runnning consistant 9.3/low 9.4 1/8ETs around 75/76 on a good run (no bogging/spinning/ missed shiftes etc.) Just recently I pulled a 9.378 on a damp track with a 2.300 60' (let off in the 60' becuase of massive wheel hop... whipers were going, coin holder emptied its contents, sun roof cover slid back, dash lights came on).
