RangeStang Posted November 13, 2007 Report Share Posted November 13, 2007 I have a question would it be easier to go obd1 or obd2 on a 95 GP? Does anyone have eather of these swaps on a obd1.5 car. what one would be easier to get performance out of? Ease of tuning the car? Thanks in advance!

pwmin Posted November 13, 2007 Report Share Posted November 13, 2007 obd2 swap is pretty easy to do and a lot easier to tune. obd1 swap may be easier (idk really), but its a lot harder to tune Quote Link to comment Share on other sites More sharing options...
RangeStang Posted November 13, 2007 Author Report Share Posted November 13, 2007 That is what I thought obd2 it compensates to mods alot better (via MAF). What do you guys think about megasquirt for tuning I would like to do it myself or have a friend do it since I am a long way from DHP. I am going to spray it eventually. We will see what will go first the 3100 or the trans on the bottle. I have 2 3400 spare engines. Quote Link to comment Share on other sites More sharing options...
pwmin Posted November 13, 2007 Report Share Posted November 13, 2007 dont waste your time w/ standalone, IMHO, of course Quote Link to comment Share on other sites More sharing options...
RangeStang Posted November 13, 2007 Author Report Share Posted November 13, 2007 Also I have a 3in hooker areo chamber muffler just siting in my garage. Will it have any adverse affects if I put it on my existing exhaust I have now? I did not want to start a new topic. Quote Link to comment Share on other sites More sharing options...

Aftermarket MSD,or a Jacobs nitrous control unit. Otherwise I am limited to about a 50 shot with stock timing right Quote Link to comment Share on other sites More sharing options...
pwmin Posted November 13, 2007 Report Share Posted November 13, 2007 just do an OBD-II swap and get a DHP Powrtuner or HPTuners Quote Link to comment Share on other sites More sharing options...

pwmin Posted November 13, 2007 Report Share Posted November 13, 2007 what car is this? i put a the same muffler on my stock 87 bonne (it was free) and i didnt notice a loss of power Quote Link to comment Share on other sites More sharing options...
RangeStang Posted November 13, 2007 Author Report Share Posted November 13, 2007 The 95 grand prix in question, the muffler I have had for three years it was free also. I am cheap Quote Link to comment Share on other sites More sharing options...
Dark Ride Posted November 13, 2007 Report Share Posted November 13, 2007 just do an OBD-II swap and get a DHP Powrtuner or HPTuners HP tuners I've heard is a little more expensive, but its better, and you can tune practically any OBD 2 vehicle with it. I guess I'm confused why putting on a new muffler would cause a loss in power. Quote Link to comment Share on other sites More sharing options...
pwmin Posted November 13, 2007 Report Share Posted November 13, 2007 i'm used to DHP cuz thats what i have and i really like it. ive heard its easier to use that HPT. if you just want it for 96+ GM V6's, i would go for it over HPT for sure, but if you want other GM stuff, HPT is the only one that will do it. btw, you need a 97 computer for HPT, but you can use a 96 for DHP. a 3" muffler probably wont cause a loss in power, but a 3" exhaust definitely would Quote Link to comment Share on other sites More sharing options...

What do you guys think about a full 2 1/2in. exhaust from manifold back. Just remember I am going to spray it and sooner than later it will have a 3400.

RangeStang Posted November 14, 2007 Author Report Share Posted November 14, 2007 Really I got on DHP's site and I could only find 97 and up applications. My brother in law works for transgo (that is where I get all my tranny stuff from) said that they started using ecm controlled transmissions in 97 although I thaught they started when obd 1.5 was used. What say you guys? If so what would I do about that just get a 97 and newer trans.? I thought they only used 4t65e after 97 who nows I could be wrong.

pwmin Posted November 14, 2007 Report Share Posted November 14, 2007 as i said before, dhp 96, hpt 97. i know cuz i got a powrtuner for my old 96 GP. all cars had to be obd2 in 96 ("american" at least). they started using e-trans before 97, maybe before 94.
