just finished chipping my p28 with a base tune and diy chip kit from phereable, i got it installed started the car and it threw a cel and wont rev out past 4000rpm, it has a solid cel i cant pull the codes or anything if anyone can please help id really appreciate it! also i have been hearing a weird clicking noise from the drivers side dash sometimes, not sure if that has anything to do with it , it has done that long before i chipped it......

 

I forgot the number, but check and see if J28 is cut (Not sure on the number) I had the same problem, my it was cut one I had s200 installed in my Ecu, but when I took it out and sold it and added a chip it from phearable it wouldn't go pass 4000rpms as you stated. I reconnected the J28(again not sure if thats the right number) and it worked, it ran fine, went pass 4000rpm, and the two step kicked in like it should. By the way it should be right on the right side of the place where the chip sits at. I'll try and get pictures of my ecu tonight and post them up and show you a little better.

 

do ya mean j1, if so i go tthe jumper installed there, please if you can get a picture right now i would greatly appreciate it!

 

Maybe it was the J1, I'll pull my ecu out and take pictures and look at it for you as soon as I find out where my camera is. But check and make sure nothing is cut from the circuit board and that everything is connected

 

i just took a picture of my chip set up this is what mine looks like:

 

Ok. Easiest thing is to cut J1 and make sure the ecu itself is still functioning properly.

If it is fine. Then you have a problem in the chipping or the basemap.

I would put money on the chipping before the basemap though. Make sure you don't have any bridged solder joints, lifted pads, pulled traces, etc.

 

ok so if i cut j1 and the car runs fine then it has to do with either the soldering job or the chip , i will try that and see what happens, and by a burnt trace do you mean a foil from the board.....

 

bump for some ecu help asap please!!!

 

i figured it out!!!!! there was a tiny i mean TINY peice of solder brade jumping two of the pins on the 28 pin eprom, thanks for all the help guys!

 

well i thought i fixed it its running with no cel but i bogs when i give it gas, im running the stock injectors now and the base map is for 450s do you think thats why.... im going to swap them out for the 450s to see if it fixes it....

 

Yes, the injectors aren't keeping up. Change them out for the 450's and see what happens. Whats the setup of the car anyways?

 

d16z6, stock block

t3 60 trim
cast manifold
2.5 in intercooler piping
2.5 in exhaust and dp
arp head studs
cometic head gasket
10psi
dsm 450s

just installed the base tune as you all know, it is running no cel but its bogging when i give it gas, im going to resolder some of the connections and install the 450s

 

bump!

 

If your map is for 450cc injectors & you are running on 240cc injectors your car will obviously not run correctly. Install the injectors properly & the resistor box. Make sure you wire the resistor box up properly & don't loose sequence of the injector clips (cyl1 is cyl2 etc..)

 

i got everything hooked up and its running great, no cel or anythng runs like normal except its boosted lol, thanks for all the help guys!
