alrighty... time has come for me to convert to ODBI.. I drive a 99 civic with a d16y8 5speed.. what ODBI ecu is perferable with this engine? I am looking at going turbo in the future.

 

P28 or P30 if you want the knock sensor.

 

cool thanks.. thats kinda what I thought but didnt want to get one then it be wrong...
what do those come out ot.. maybe i can get one out at a junk yard here.

 

good luck, they go fast...

USDM
P28 - 92-95 civic EX coupe, civic SI hatch, DelSol Si
P30 - 92-95 DelSol VTEC (do not pick one out of a 96-98, it's not chip friendly at all)

 

ya i just called a place and they go for about 150... i think ill find one online.. thanks for the help.. some guys can be dicks on here. wish everyone could just get along..

 

you can get deals for 125 some times, but most of the time they go for around 150.

do you need it right away?

 

no.. just doing some early research for when I decide to do this.. not sure if i sould do this before I upgrade the cam, springs and retainers or after.. can you control vafc with a computer program hooked to the ecu? I mean can it work like a vafc controller?

I'd change it before, if something goes wrong you only have one thing to question. Plus you can always fall back to your stock ECU if everything gets messed up.

a VAFC works the same with a chipped ECU as it does your current ECU.
All though if you went to Crome or Uberdata, you'd be a lot better off than with a VAFC.
basically a Hondata setup with a lot less cost, but it's totally DIY.

when you're ready, send me an IM. I may have what you need.

 

sweet, sounds good... ill save up and see about getting me a p28... they seem to be more common and less expensive.. not sure why you actually need a knock sensor anyway or what its actually for. with the pinouts I should be able to make a odb2 to odb1 convertor.. looks easy enough.. what do you think?

 

I made one a while back, only difficult part is getting the female OBD2 plug. The OBD1 male plugs are fairly easy to snag at junk yards.
then again if you need an OBD2 female plug let me know. I have a few ECUs sitting here that I don't care about.

I'm not trying to sell stuff, really. I just have a lot of crap sitting around.


A knock sensor protects the engine from predetination due to a bad batch of fuel or inpropper tuning. Not really needed, but IMO a good safety device.

 

p28 ecu

 

try gsr chipped

I'm curious why you suggest this. once chipped the only advantage the P72 has is the IAB control and the y8 doesn't need that.

 

Pm 93turbo16. He'll get you setup for a damn good price.

Or play with your timing

 

or play with my timing.. hehe
(is that waht they call it now?)

 

ok... so I had a laptop given to me tonight... awesome!! and it looks like the next chance i get i'm grabing a p28 to chip.. thinking of uberdata and ostrich.. any ideas??

 

you are going to have to buy a harness jumper to convert your cars obd II system to the p30/28's obd I system but thats it

 

ehh.. with the pin outs.. i can make one
