Has anyone flashed their ECU, Is it really big gain, How much does it cost? Who does this?

 

well i believe its like 500 dollars from techno square they are in simi valley, most people do it to tie their mods together especially their breathing mods after leaning out, but sometimes even this wont fix the problem.
others may do it to bump up the redline and remove the speedlimiter, which is useless if your not making any big power up top.

 

Did Techno Square move? I couldve sworn that they were in Torrance.

 

According to their website, they're in Torrance.

So is just better to use the money on other add on's like exhaust?

 

Yes they are in Torrance on Normandy 3 blocks or so from Ricks & Ronnies. The reflash is the final tuning devise after you do all your engine breathing mods. Both cars I have have TS reflashes.

 

JC, I recommend doing the reflash only after you are done with all performance mods that you want.

Since I'm done, I'll be getting this probably later this year. This will get rid of the speed limiter and I guess get my mods to work better and more efficiently.

 

From what Ive seen in dyno charts, the TS reflash balances air/fuel ratios pretty well throughout the rpm range but doesnt really add much hp or tourque (like maybe 2 or 3 if youre lucky depending on mods).

 

So it would be better just getting a good exhaust?

 

I think so. With just my Invidia exhaust and no CAI I put down 245 on a dynojet. 2003 model Zs like mine usually baseline ~235 so I call that an effective mod.

 

Hmm, but if you need to reflash, for whatever reason (let's say new mod/s), it's another $500 no? Wouldn't it be a bit wiser to go stand alone?

 

Any updates to an already reflashed ECU costs $150.
