how hard is it to chip an ecu??? i want to try it because i have been practicing my soldering but i dont have any education on the subject mater... if it is possible, can i just buy the chip or do i need it installed and programed?? i tried the search but the archived is down and i didnt find anything..even if i cant do it myself i would like to be a little more educated on it just t learn something new ya know... please give me any info if you can, thanx

 

i can help you out.......what ecu were you planning on chipping. If you want to chip a p72, p30, p61, p28, etc. obd1 vtec ecu's.....its easy. You can purchase a chip off of me and solder it in your ecu yourself or have me solder the program chip, etc. If you want more info, PM me back. obd2 ecu's arent even worth chipping! LOL

thanks
Jay

 

its a p74, as you know non-vtec but i wanna fix my fuel map and my rev limiter cuz my fuel cut off is way early..but iono if its worth it, imight just wait till i do my swap but that wont be for a while..iono what to do ay suggestions??i wanna do it though,ill keep in touch mang thanx a million

 

yeah..there are program chips for the ls ecu as well. I think the programs will just make you run a little more richer, have more agressive fuel maps and have a higher rev limiter. But seriously, i recommend building up your motor first then doing the ecu.

 

how about chipping vs VAFC? They both change the fuel map, and a chip can mess with the rev limiter, but is that it? How do you tune the fuel map? Is it worth it to buy one of those cheap chips on ebay? Are they cheap just cause you gotta solder them yourself? I dont quite get chips.
