well, i finaly got this thing running on a decent street tune and i freakin love it! its fun as hell does 70 mph burnouts like it aint nothin. im running a ls motor with a .48/.60 DSMs and a converted p28 on crome. i was driving around yesterday and i layed into it one good time and the CEL comes on and it starts backfireing and spitting and sputtering and wouldnt run for ----. if i slowly push on the throttle it wont do it everytime only some of the time but if i just nail it in 2nd or 3rd it starts doing it. i go to check the codes and there arent any...? i dont THINK im over shooting my stock map sensor at a little less than 10 psi but its always a possibility. the CEL has been flashing randomly befor too but i never throught much of it. i also got my 2.5 bar maps from freescale thursday, does anyone know how to wire them yet?

code out your cel's error code.. and get back to us.

instructions on how to do this:

check your chip out if you have a burner ... the cel maybe set-up as boost cut,vtec light or any option.. not sure if crome has the same options as TE but it worth a try

thats the problem, there isnt one. i know how to get codes...jump the connector and the light stays on like when there are no codes....but it goes to hell and cel comes on when u get on it. i dont understand why it worked fine for 3 days then it went to ----...

Got my 2.5 bars Thursday also. I just wired mines today. In a OBD1 DX the wires were different colors. OBD 1 CX and VX has the same color scheme as OBD 0 cars. Weird...

Hellbert

looking at the top of the sensor from left to right what pins did you hook the wires to? should have a 5v ref., a return, and a common or something. im going to check my programming today and see if itll tell me anything

Pin 1 is the pin with a notch on one of its leg:

Pin 1 = Reference wire should be white on the car side (for some reason mine was pink/wht)
Pin 2 = Ground usually Green/Blue
Pin 3 = 5v should be Yellow/Green

Thats for OBD 1 DX wiring...I know VX and CX map sensor wire are like OBD 0 colors one of the color is red/something and its the 5v wire. Hope this helps.

thats on the 6 pin free scale sensor that everyone was getting for free?


i fixed the problem with the cutting out i think. i hasnt done it since i went back and reburned my chip. i took some fuel out to bring my af ratio back up around 14. i reckon it was a bad burn.

yups...the others pin 4-6 are internals used by the motorola 2.5 bar map sensors. Go by what it posted at xenocron's webpage.

Hellbert

haha yea i just saw that earlier today when i was looking around on xenocrons site. i appriciate the help though man

has anyone ever heard of a code 68? thats what i was getting befor i reburned my chip. then i hit a big bump in the road and broke 2 turbo mount bolts...damn hondas...
