NEED HELP WITH CHIP INSTALL ON OBD1 P72!!!!!
 

Well i bought a pyr chip that came with the socket, another small chip, and a jumper wire, and instructions on how to install it. A friend of mine who installed chips previously did it for me, and we followed the instructions correctly, but after we put the ecu back together and put it in the car it did absolutely nothing! Vtec stayed the same, but my redline didnt change and thats all i want from this chip. At first i thought i had a bad chip, so i had it replaced with another one, and nothing changed. the only thing that i can think of is that we soldered the socket in the wrong place!! here are some pics of the ecu and the chip installed, is there anything wrong with the installation? thanx in advance!!

Blue arrow shows the other little chip that came with it, yellow arrow shows the socket as we soldered it

well on the chip it says vtec-4400 in which case VTEC did stay the same and redline 9100 well you say the red line didnt change . . . idk

just saying that vtec stock is 4400 (on a gsr and the 2ndary butterflies hit at 5700)

your red arrow should be a resistor. the section "J1" right next to the red arrow should be your JUMPER wire. section where "C52" is, should have a 0.1µf ceramic disc capacitor. from the pictures i cant tell if the chip is installed the correct way with the notch pointing towards the left.

yeap thats the only three mistakes I see in order
to work well...

place the resistor where you placed the jumper wire
the jumper wire in the J1 slot
and the missing cap
after that you should be fine..
I bought a p28 that was missing 3 items
2 caps and the jumper wire..
bought those and installed then it worked beatifully..

thanx for the replies guys, i just wanna make sure that im getting what you are saying here just to be on the safe side. The jumper wire needs to be on the "j1" slot, i should have a resistor in the "r52" and a capacitor in the "c52" slot and the notch on the chip has to face to the left? So after im done with all that everything should work fine??

Re: NEED HELP WITH CHIP INSTALL ON OBD1 P72!!!!! (SloGizzer)
 

Pics are kinda blury and i thought i saw a capacitor in "c51" but there isnt one in there so grab two capacitors and your ecu should work.

Re: NEED HELP WITH CHIP INSTALL ON OBD1 P72!!!!! (00b18b)
 

you have the jumper in the wrong spot. it needs to be on j1.

Re: NEED HELP WITH CHIP INSTALL ON OBD1 P72!!!!! (94goldjungsr)
 

indeed move over the jumper wire to J1 location.

R52 should be empty. Caps are not required on C51 and C52, I personally do not use them.

Re: NEED HELP WITH CHIP INSTALL ON OBD1 P72!!!!! (eg6ajk)
 

i do use them. and rec them as per pgmfi.

Yup, it will work fine without capacitors. Just move the jumper wire to "J1" and everything should be good to go.

well, i just moved the jumper wire to "j1", and plugged the chip in the socket, and then i went to start the car and got a cel!! i tried to rev it, but it wouldnt rev past 3000 rpm. i have no idea whats up with it now!

Re: NEED HELP WITH CHIP INSTALL ON OBD1 P72!!!!! (SloGizzer)
 

you are in limp mode.

Re: NEED HELP WITH CHIP INSTALL ON OBD1 P72!!!!! (94goldjungsr)
 

so what am i supposed to do about this? I dont know why eveything has to be such a pain in the ass when it comes to gs-rs. what do i need to do to make this thing work, im getting my cams next week, and i would like to be able to rev past stock to make some decent power with them. somebody please hellllllpp!!! http://images.honda-tech.com/set1//smile/emcrook.gif

Re: NEED HELP WITH CHIP INSTALL ON OBD1 P72!!!!! (SloGizzer)
 

resolder all the connections and reburn the chip. one of those is your problem.

Re: NEED HELP WITH CHIP INSTALL ON OBD1 P72!!!!! (94goldjungsr)
 

well i bought a new chip that came with capasitors, redid everything, and as soon as i solder the jumper into the j1 slot, i go into limp mode, so i pull the jumper out, and everything goes back to stock!! i have no clue what could be wrong!! has anybody had this problem before, cuz i feel like giving up already!! this is the 3rd chip, and the problem is still the same. if anybody has any idea what is wrong please let me know!!!

Re: NEED HELP WITH CHIP INSTALL ON OBD1 P72!!!!! (SloGizzer)
 

make sure you did the install / burning correctly. its not hard, at all.

Re: NEED HELP WITH CHIP INSTALL ON OBD1 P72!!!!!
 

Same problem here my ecu p30 dont go more then 4000 rpms i jump j1 i set i items they send me it was 4 little squares 2white for c91andc92 and 2 brown for c50 andc49 plz help...

Re: NEED HELP WITH CHIP INSTALL ON OBD1 P72!!!!!
 

this is why you PAY someone who knows what their doing to install it it's like ppl who think an s300 is drop in...it's not I had to get my tuner to install it.

Re: NEED HELP WITH CHIP INSTALL ON OBD1 P72!!!!!
 

I know wat i did i installet the way its suppose
