Has anyone used the Jet Chip http://www.performanceproducts4truck...ance+Software+ or anyother make? Are they worth the money? How do they effect the MPG?

After searching and doing alot of reading it doesn't look good for the Jet chip.

 

I concur.

 

 

I dont think they make programmable ECUs for the 4runner/taco platform

 

Ummm, it depends on how far you wanna take it, and how much work you wanna do. Most of us run "piggybacks" (PerfectPower SMT-6 & -7 or SplitSecond FTC1) to get control of fuel delivery and timing, but...

There's a family of 100% ECU replacements on the market, all are VERY programmable and each is adaptable to 99% of the engine setups available anywhere. One is the MegaSquirt - funny name, POWERFUL controller. It's a bit of work to get it up and running, you kinda' need to be at least familiar with programming in C, but there's nothing like it.

 

Check out gadgetonline.com & read his articles. He did the R&D for the URD kit that he markets & has some input on the jet chip. Apparentlly it didn't fly.
