Default New ECU?

http://www.powerchipgroup.com/gfx/da...ts/Lex0003.pdf

Check this out guys. They have it in Australia but I am pretty sure it is easily imported. Now tell me how does 1KW translates into HP? Lazy to look it up.

Default Sketchy!

1KW = 1.34 HP
1NM = .72 lb/ft

I'd be pretty weary of a company that produces as many chips as they do. If you are producing a chip for every car sold in Australia....how much of your R&D budget are you devoting to each and every different application. Secondly anybody who refers to a chip upgrade as "viagra for your car" is suspect to me. Maybe they do advertising a little different down under. Have you checked to see what kind of gas they are tuning those chips to run on...etc. Do they even sell 93 or higher octane in Cali?

They have my car listed at 280 HP Stock......which in the US is rated at 290HP. My guess is that they are tuning for the same engine that would be sold in the Japanese market and thus subject to the Japanese market voluntary restrictions to 280HP (could be 278HP exacly..can't remember). I'd look elswhere for a chip.

Read this article and then decide if you still want to waste your time on these guys:

Default this part of the interview absolutely slays me!

"Wayne Besanko: We've actually looked at the benefits of owning a dynamometer and we have made a business decision that it is better for us to simply pay for dyno runs on an ad hoc basis."

Remember TOM's does make an ECU for our computer. I imagine it's pretty hard to get imported though.

Do you have any specs on TOM's? That interview sounds kinda shady so is the Powerchip.

I only have the scan from the 2000 TOM's catalog. I don't know if it would work with the english ECU.

I couldn't find anything on it online, but I'll scan it in for you.

Default Tom's ECU used to be listed on...

Carson Toyota's web site along with a stroker kit for the 4.0L. If it's an ECU for the Japanese market celsior....remember..that they have 100 octane available at the pump over there..so a japanese market ECU may be a little to aggresive for 93 octane. If it's made just for the US market...thats a diff story.
