Here's the problem I'm about ready to purchase a stage 3 with datalogging for my car but....all the info that I can find on these 2 ecu's is that the Rev Limmit can oly be set to a maximum of 9000rpm.???!!! WTF I just need to to go to about 9200~9500 !! Also I can't find anyone who wants to tune the PW0/PR3's they all can do a great Job on the OBD1's but nothing for the OBD0

Any hrlp you guys might be able to shine my way would be of great help
Thanks

 

Hey Dave...I just called Hondata for you, but they're out of the office for the day. If someone doesn't answer your question by tomorrow morning, I'll call and speak with Doug for you.

Thanks Bro .. I have e-mailed them 5 times but they never get back to me I really need to find this stuff out bro .. also about the tuning map's for the OBD0 Ecu's

 

Don't worry. I am sure that it can be set to what ever you want. Some guy on the website spins his drag car to 10,500 with a limiter at 11,000.

 

Ya but I think that the ECU that he's running is OBD1 though??

 

I think that he's running a p28 based Hondata...

 

UP ^^^

 

obd 1 convertion harness ????

 

It's been done...had a friend purchase the harness from Kenji, runs great without a problem.

 

As I have said before, you should get an adapter harness and run a p28 ecu.
It is SOOOOOO much better than the PR3/PW0 ECUs

 

Only the P72 currently supports the extended tables to rev beyond 9000 RPM. I am not sure if that will change with ROM Editor v3 or not.

I have know problem running a adapter harness........But I don't want to run a P28 ecu...If I don't have to... May be a JDM p30 or P61..?? Don't know

 

p28 works fine. sometimes better than p72/30

 

Hmmm Howmuch do they go for used in the US.??? might have to break down and get a adaptor harness

 

you can sometimes find p28 for 100.

 

Cool Thanks Now just need to find some one who has a clue for burning a Program For the Stuff that I have in my Car ...hhhhmmmm Steve.?? hhahhhahaaa

 

Yeah, I've picked up like 3 of them on eBay for $100 shipped.

i can help
fly me to japan

 

hahaha Speaking of which it's really cheap to Japan right now too.. hmmm make it from the East Coast to LAX buy your self and I might cover the trip to Japan with a place to stay.. . .!!! no Bull ****

 

hmmm.... shouldnt be a problem
but i got PLENTY of places to stay lol

 

I will be converting from OBD0 to OBD1 as well just so that I can run the P28/P72. You'll need an obd1 dist, and injectors.

 

I just confirmed it with Doug at Hondat...9000rpm is the maximun rev limit that you can have while using a PW0 or a PR3...anything higher an you need to convert to OBDI...thanks for the help Doug.

Dave...looks like back to the drawing board again , it just figures that it's something that we didn't think of

 

Is that all you need? I want to run a B20vtec with B16a1 head, will obd1 still work for the B16a1 head?
P28 is GSR ecu and P72 is the itr right???????

 

P28 is a civic EX ecu, P72 is a GSR ecu...either will work for you...
