i have been reading quite a good deal of information on the obd1s and 2s on this site, but most threads did not provide a complete answer, so once again what are the advantages of having
a) obd1 over an obd2
b) chipped obd2
c) chipped obd1(?)
....for a 2000GSR.

and is it true its as simple as plug an play? and what are the possibilities for deterioratin in drving quality?

 

simply put, OBD1 is what most people use because there is less sensors and less things to worry about malfunctioning. OBD2 computers require a piggy back system if you want to chip them i believe. so basically OBD1 is better. someone correct me if i gave out false info, but thats what ive been told.

 

is it legal to have an obd1 in an obd2?

 

im not totally sure if its illiegal, but ive seen it everywhere.

 

• OBD-I Reversion:
The main reason why people revert to OBD-I is to facilitate the switch to a standalone, user-programmable aftermarket engine management system.
There are very few (if any) performance gains that come from reverting to OBD-I. It only facilitates the installation of systems that provide more tuning flexibilty.

Furthermore, the standalone engine management is designed for use on very high-output, "radically" tuned motors. If all you intend to run is bolt-ons and a built head, a piggyback controller like Apexi's VAFC is much more cost effective.

• On the topic of "Chipping": The outstanding majority of performance tuned ECUs simply tweak the ignition timing curve... advancing the ignition timing. The gains are fairly mild unless you get into custom tuning to match specific modifications.

And if you're considering the use of nitrous oxide, the advanced ignition timing from a "chipped" ECU will increase the risk of detonation while using the nitrous.
Every manufacturer of nitrous oxide injection systems warns against the use of "chipped" ECUs in conjuntion with nitrous.

Basically, ECU mods are a facet of performance tuning that supports the modifications to the engine. If you're planning on bolt-on modifications (intake, header, exhaust, cams) the stock ECU will be able to handle it.

Hopefully, this clears things up a bit.

 

In most states with emission inspection, it is illegal to revert back to OBD-I.

[Try it in California and you'll be shot. ]

 

yea the emission ppl in cali would probly shoot u those damn zealots

 

haha, thanks otherDave. that was exactly what i wanted to know.

 

:cheers: Happy to help. As soon as I'm done with finals, I'm going to start adding to the Integra FAQ again.
