ecu tuning?
 

i got a 89 full size 5.7, that is stock except some freshened up older vortec heads and magnaflow exhaust w/ 40 tips. it was recommended that i do an ECU tune to summon some lost horsepower. would like to get as much info as possible on type of chip or tuner that would be recommended.

I have a LOT of information regarding this. Please contact me and let me know what you need.

thanks for responding, i'm looking for programmers that are user friendly! i don't want to trial and error on something so critical to my engine. wondering if their are pre-programmed chips that are recommended for a 350 5.7L chevy. if not , what is the most successfully used programmer, that includes comprehensive instructions. any input is appreciated!

Check out moates.net (http://moates.net). They have a USB chip programmer that is user friendly. Do you have the part # of your computer? I'll take a look and see which chip you need to use.

For me, I picked up 29SF512 flash chips for a few bucks a piece, and an EPROM programmer for about $35. The EPROM programmer was pretty crude (its NOT that moates.net programmer), and it was not very user friendly at all, but I'm an engineer so I figured it out.

I downloaded the code from my chip, then turned it into assembly language. I found some commented code on the internet and I just fixed it up to match mine. This way I can just recompile the file and program it. All the different locations are commented so I know what does what.

Anyway, get me the part # of your computer and I'll tell you exactly what you need.

Stupid newbie question, but are there any free/cheap software for a 90 S10 Blazer w/ the 4.3? $35 for a EEPROM programmer and downloading some software is within my price range.

sorry for the thread jack but i too am looking for a user friendly programmer for a 94 s10 blazer vortec v6... any help is greatly appreicated
