well i have the OBD1 GSR ECU and the complete change over already. I'm contemplating on going with either of these routes:

1) keep OBD-0, sell my GSR obd1 ecu and buy a PR3+FPR and ARC for the money i get back for the GSR ECU. Run it at 48-52psi and change vtec crossover to stock B18c1 spec.

2)convert over to OBD1, keep my ECU


what would be the better and more effective route?
*I personaly always like doing things thr right way the first time around. But in some situations other options can prove to be possibly better.

You will not be able to control the GSR butterflies with the PR3 ecu...unless you get it chipped or something. I say just stay with what you already have, keep the gsr ecu.

 

I second that! Although the motor will work with a PR3/PW0, it is not the best way to go. First of all, you must sell your GSR ECU at a loss and try to source a PR3/PW0. And these are not easy to find. Secondly, you will ALSO need to get a PR3/PW0 distributer, as a GSR distributer will NOT work with a PR3/PW0. These distributers are even harder to find since they tend to fail quite frequently. Not to mention the fact that you may find yourself trying to find another one from time to time due to failure. And let's not forget about the expense of a fuel controller, fuel pressure regulator, and (most importantly) the dyno time to tune it right. But this is not the end of the disadvantages associated with using a PR3/PW0. These ECUs won't give you as good of fuel economy. They won't control the IAB (as the other guy pointed out). And you will have to use that stupid, totally retarded twin oxygen sensor setup. This means having to hack up any header you buy and have two bungs welded in. Do yourself a HUGE favor and rewire to use the P72 (GSR) ECU.

 

ok well now that it seems that question has been answered.. maybe i could hijack this post?
i have the same gear i think.. i have a 96 b18c1 and a obd1 gsr ecu.
i have two questions..
1. can i use my distributor and injectors somehow, since they are obd2, maybe rewiring? and is there any info on the web bout this if i can?

2. what would be better than running the gsr ecu? are the only options hondata and aem's ems? what are your thoughts on these? other than they are hella $$$
thanks in advance and consida this mo fugga hijaxed

 

OBD2??? pain in the **** you don't need. sell ur stuff for some obd1 or obd0 injectors and dissy, if you get a skunk2 intake manifold you can run any obd1 obd0 ecu u want (no secondaries). id go obd1 more options down the road.

alot of people sell jumpers to convert to obd1 or if your cheap like i am convert it urself
search for: obd1 conversion

1. You can use the OBD2 distributor and OBD2 injectors, but you will need to repin the plugs to match. Also, the OBd2 injector clips will not match as well so you will need to resolder on the correct plugs. And take out the resistor box if you have one.

2. Hondata is a great system. Any standalone, in my opinion, may be overkill for a car that doesnt have any mods. High compression, boost, nitrous, I understand....but for a stock gsr with like a header or something....it is nice to have the security of a Hondata system, but I think the $$ could be spent elsewhere.

That is incorrect. The OBd2 and OBd1 distributors are both compatible. Same for the OBd2 and OBd1 injectors. Only difference is the plugs.

bump for a more info.
BTW if i was to get a PR3 and hondata s100, wouldn't that (hondata) allow me to control the GSR intake manifold /secondary runner?

just curioue.,..... I'm leaning towards OBD1 at this moment.

I am not sure. In any case, you still would not be able to run the GSR distributer. And you would also need to run that stupid twin oxygen sensor setup, requiring you to make a mess of any header you buy.

 

an-r can make a custom bung hole/flange for me when the built it i belive.

Yeah, or you can do it yourself. Either way here is where it stands:

Buy conversion harness
Use already aquired OBD1 ecu, distributor, and 4 wire O2 sensor

Sell OBd1 ecu
Find OBD0 ecu
Find 2 1 wire O2 sensors
Find OBD0 distributor.....Find another one for when that one dies
