If you convert to obd1 how much more power will you gain? is it worth it?

no

A OBD1 ecu doesn't give you more power. Nor another ecu. So just converting does nothing. Tuning the ecu however gives you some power. So basically people convert to OBD1 cuz its easier to tune. Its the tune that gives you power not the ecu conversion. You need to rephrase your question or need to read up a little of what the conversion is for and consists of.

well I converted from a stock p72 obd2a to a stock p72 obd1 ecu today and I felt a difference. so why did you say it doesnt make a difference unless its tuned? anyone one else care to explain to me why I felt an increase in power?

the obd1 p72 probably has a more aggressive timing and or fuel map, which is

KINDA like it was tuned. in your case this might be a bad thing, the ecu may be

making you run rich because it is not tuned for your motor. even worse, you might

be running lean! get that ecu tuned before you motor goes boom.

assuming you're engine is basically stock, no cam work, different pistons, or something like that. then you should be using the stock ecu that was designed for the engine you have in there. If you do have mods however that require some tuning, then like the other guy said, get it tuned before it blows up.

X2 Its still pretty much the same ECU, the OBD2 version uses some extra emissions sensors, thats about it. It should work the same, the only thing OBD1 is nice for is tuning and because OBD1 uses fewer sensors you have less to go wrong, thats really about it.

alright guys.. Im trying to get a hondata s200 before I get it tuned. but its crazy how much of a difference I felt just converting to a stock obd1 ecu. oh and I just have minor bolt ons like a skunk2 pro series manifold and dc ceramic headers with an ebay air intake. but I had that on when I was already using the obd2 ecu.

So glad to see this post in here.

Good to see you posting in this section more often. Keep it up.

haha i try to post useful info. the butt dyno being one of my gems

EPIC LOL

haha butt seriously obd1 computer was alot less emissions oriented than any newer computer. so is possible little extra spark advance... which would produce extra nox in exaust so it gets a little less advance in later gen factory tunes and less peppy feeling.

engrish much?

I dont get it

D16SiHatch

It means you think you feel an increase or decrease in power just by how your mind perceives the situation. If in your mind you think changing the ecu might make it faster then you are more likely to "feel" a difference after making the change. just like for example if someone gives you a pill and tells you it should make you feel less depressed, and then sure enough you feel better, while all along it was a placebo.

i agree with D16SiHatch, my friend did the exact same thing to see if he'd feel a difference in obd2 and obd1 and he said it felt the same, so it could be just some wishful thinking on your part. i would just get a chipped p28 from phearable so that you have a basemap to run all the mods you have.

I have another view to add to this topic....Will using an obd1 ecu on an obd2 motor (lets say GSR) do any harm? I doubt it, but I just have to know before I go buy a 94-95 P72. What about the secondary butterflies? Will they still function?

raidacaipo

I dont know if it will do harm since Ive been using that same setup for quiet a while now.. but yes it works for the butterflies too
