Okay.. so i just got a chipped ecu, 3 bar map sensor , 255 fuel pump, 440 injectors, aem fuel rail, and aem regulator - goign to be installed later.. but i start my car it revs to 3000rpm and throws a check engine light if i let off the gas it shuts off.. and if i stay on it revs back and forth from 2000 rpm to 3000 rpm.. im getting a code 7 which is the throttle position sensor , i never had this problem before.. so y now?! any help thanks..

There's a chance that it was just time for the TPS sensor to die..

you sure youre not using the OEM map sensor plug? they are identical with the exception of wire colors

well its really messed up.. I hooked me old ECU back up that was kinda fried.. it runs good, but just throws the map sensor all the time.. and it dont even throw the TP sensor with this one plugged up ro anything i can tach it out all the way... I switched the plugs making sure im not using the map sensor for it, still didnt fix it with the chipped ecu.. we put the stock injectors and everything back to stock ran the chipped ecu and it still dies wont run at all tach to 2500 rpm and dies.. but runs fine with old ecu which is burnt o.O hmm We say the chipped ECU is messed up..

well, if you have an ecu thats burnt.... then you shouldnt have it in the car. chances are that burnt ecu may have caused the the problem you are having. who chipped the ECU? it could also be a problem with the program

Phearable.net . this is the 2nd ecu i got from them, 1st one i had worked good.. i opened the case up and i seen some sort of rubbing marks on the board.. like Red o.O i dont think ti should be there

i actually socket ecus myself. there is often red or yellow grease pencil markings on them. this is not uncommon. if you think its the ECU, send it back to them to be tested

Carbcivic

im in the process emailing them.. they are telling me its something i need to get Dyno tuned................... o.O i dont see how that will fix this

slambedcivic

possible TPS issue. i can dig one up for ya if you want.

slambedcivic

you say that all of that stuff will be installed later.... what is the setup you have now?

Carbcivic

well i had the ECU chipped for the 255 fuel pump which is in, aem fuel regulator, which was on but i took it off seal was shot on it but its going back on soon, aem fuel rail, 440 injectors, and 3 bar map sensor i had all on during the new ecu test... it ran with the old ECU ... o.O with all that one lol but hte new one is messed up.. i put the stock injectors and regulator back on and it dont run right yet.. but ya how much would u want for the tps?

Carbcivic

also.. wouldn't the old ecu throw a tps code too??? its weird cuz only the chipped one throws that code ..
