cant seem to get a clear answer...
when going obd1 in a 01 base lude
i need a chipped ecu such as a p72 w a s100 hondata chip (or any chip for that matter like crome neptune eCtune etc...)
a jumper for stock harness to new ecu
anything else?
do i need to change dizzy? change knock sensor? or is that all taken car of in jumper?
thanks

 

are you using obd1 for less restrictions or are you doing a swap?

 

to tune a cai, hytech 4-2-1, and full 2.5" exhaust and maybe nitrous in future

 

+1 same question here. BTW to help with tuning u should get a fuel pressure regulator and maybeee some adjustable cam gears to advance timing a bit.

i was tuning my apex and my car would stay rich in high rpms no matter what, tuner recommended a FPR and Cam gears but im gonna switch the ecu to obd1 for proper tuning.

 

ttt

x2. Havent changed over because havent found a clear answer how to. I have an SH though. I know ATTS will be lost but i intend to take it out in the future.

 

there is this: https://honda-tech.com/zerothread/2266933

there is this but it doesnt specify. guy who sells ecus in my area sells me a chipped p72 with a h22 base map for crome, data cable installed and obd2 to obd1 harness all for 350 and 275 if i want a p28. Im definately going with the p72 but he didnt tell me if i needed anything else, i asked but all he does is sell the items mentioned. BTW are those prices ok?...im just waiting for a clear answer


....btw...BUMP

ive read all that in the tuning faq and the "whats needed to tune" link dont work

for all the poeple saying go OBD1... i wonder who has acutally gone odb1????

cuse apperently noone can answer this question

I'm assuming that you made a type-o in this post and that you actually have a Type-SH Prelude ( I made that assumption based upon your later posts that mention the ATTS system )...

I have spoken with Nick at Jotech Motorsports in the past about this. He told me that the wiring harness takes care of all of the issues regarding the knock sensor and distributor. Please keep in mind that this is what I HAVE BEEN TOLD, and I do not claim responsibility for the validity of this statement.

 

in both posts ive said its base not sh
i guess best i can do is spend the 300 or so on
chipped p72 ecu w base map for prelude, a jumper, and see how it runs


come on.......................................
someone has to have done this!?

 

I have done this, I have a 2000 SH. Then rebuilt my head with skunk 2 everything and skunk2 pro 2 cam shafts. and put p28 with hondata s300. even took out my 2nd o2 sensor. I love hondata, but im sure just a chipped p72 will work fine.

 

i have just recently went to obd1 ecu. the only problem i have run into is CEL 9 (cyp). after reading all info from this site and others, i believe it is due to the cyp sensor being worn out, not putting out a strong enough signal for the obd1 ecu's liking. you can go to obd1 dist. if you want, some work envolved. if you get a p72 you can still use iab. both obd1 and obd2 have the same sensors just different places the. this all stuff i have read on different forums, the info is out there

 

i can live with the check engine light on, ive had it on for a while because i have no cat.

ive been searching and saw that even if i put cam gears to advance timing, i need to do a obd 1 distibuter conversion to avoid a CEL from the advancing the exhaust gear. BUT do i still need to convert to obd1 distributer if i change over to obd1 ecu and install cam gears? Wouldnt tuning with crome advance timing also meaing i really wouldnt need the cam gears?

 

check this is you want to convert to obd1 with an hwwa1 or h23 distributor.

i also heard if converting to obd1 you have to change the oil pump to one from a obd1 h22 does anyone have info on this. Also does anyone have pictures of the wiring for the distributor, i have read the Distributor Conversion page but im a little confused???

 

from my understanding all you need is the chipped ecu and a jumper
should plug and play
you can get more indepth tuning w an obd1 dizzy
but not a must


someone confirm...

i got my cpu from a junk yard for 15$, bought a S300, and got a wiring harness from rywire.. I could be wrong, but i dont remember needing anything else.....

 

does anyone have an actual picture of what the wiring looks like for the obd1 dizzy on an obd2 h22?
