RobertISaar Posted April 29, 2007 Report Share Posted April 29, 2007 what all will i need to convert a 95 monte ls to OBD2 so i can actually tune the motor? i dont care for ABS, and dont have cruise control if it makes a difference. if you could, list a good estimate on price and how hard its going to be to do this. and are there any decent, cheap tuners out there?

RobertISaar Posted April 30, 2007 Author Report Share Posted April 30, 2007 i've been looking around and found megasquirt... i'd have a very wide array of stuff that i could do to tune my motor with this, right? Quote Link to comment Share on other sites More sharing options...
digitaloutsider Posted April 30, 2007 Report Share Posted April 30, 2007 I'd take OBD-II over megasquirt. MS is really more of a hobbyist thing.. I wouldn't put it into something I drove every day. Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted May 1, 2007 Author Report Share Posted May 1, 2007 seems like if you messed around with it enough, it would be as reliable if not more than any factory computer. i wouldnt know how to shift an electronic transmission without the PCM either. guess they need a standalone controller or manual tranny.

RobertISaar Posted May 1, 2007 Author Report Share Posted May 1, 2007 found something on ebay http://cgi.ebay.com/ebaymotors/97-Lumina-Ecu-Computor-3100-v6-Cutlass-Century-Regal_W0QQitemZ330114862448QQihZ014QQcategoryZ33596QQrdZ1QQcmdZViewItem thats an OBD2 computer, right? what else would i need for a conversion?

19Cutlass94 Posted May 1, 2007 Report Share Posted May 1, 2007 For a conversion, youll need an OBDII wiring harness, all the extra sensors, the ports, computer. Sounds MUCH easier than it really is... Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted May 1, 2007 Author Report Share Posted May 1, 2007 dont suppose you know where i could get most if not all of the stuff listed. and maybe a guide? Quote Link to comment Share on other sites More sharing options...
digitaloutsider Posted May 1, 2007 Report Share Posted May 1, 2007 A junkyard. OldSkoolGP just converted his GP over to OBD-II. You may want to get in touch with him for any advice or tips. Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted May 22, 2007 Author Report Share Posted May 22, 2007 decided to bring up this idea: what all would be required to convert to OBD1? and what would i lose over my current 1.5 setup? Quote Link to comment Share on other sites More sharing options...
19Cutlass94 Posted May 22, 2007 Report Share Posted May 22, 2007 its a waste of time to covert to OBD1... Quote Link to comment Share on other sites More sharing options...
Roadzombie Posted May 23, 2007 Report Share Posted May 23, 2007 I'd take OBD-II over megasquirt. MS is really more of a hobbyist thing.. I wouldn't put it into something I drove every day. Eh, I have to agree and disagree on this one. MS is a WHOLE lot more tuneable than OBDII, but it doesn't come without having to have a firm grasp on engine tuning. You would definately get more out of a MS box, but it isn't something you wanna mess with if you "sorta kinda" grasp tuning. I had MS installed in my old Probe GT. I was able to eliminate boost cut and dial in my fuel map to go from a stock 145bhp to 215bhp (I miss turbo...). Granted, this car was also a MTX so I didn't have to worry about controlling an automatic transaxle. This car was also my daily driver. Once you get everything dialed in, its just as reliable as an OEM ECM (provided your install is done in a professional manner). But I will restate once again, MS is NOT for the casual tuner. It is open ended in it configuration which means there is no "safetys". Results can range from excellent (if you know EXACTLY what you are doing) to catastophic (if you THINK you know what you are doing). My Ranger was ODBII an I was able to tune it quite nicely as well...its actually where I started learning how to tune. I would highly reccomend going OBDII over MS if this is your first try at tuning. Its a whole lot more forgiving. Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted May 23, 2007 Author Report Share Posted May 23, 2007 alright but whats your view on going to OBD1. i dont think i'll lose anything in the process and i'll have tuning ability, which is what i'm going for. Quote Link to comment Share on other sites More sharing options...
FordBoy Posted May 23, 2007 Report Share Posted May 23, 2007 i have OBD1 i hate it get the stuff for OBD2 from a yard and swap out Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted May 23, 2007 Author Report Share Posted May 23, 2007 i have OBD1 i hate it get the stuff for OBD2 from a yard and swap out whats so horrible about it? the fact that you'd have to burn a new prom for every little change?

FordBoy Posted May 23, 2007 Report Share Posted May 23, 2007 personally i just dont like it could be the fact that you have to relearn the idle (mine wont do it for some reason i try and try to relearn it but it wont i have to wait until it learns on its own from driving it for 1 or 2 months) that coould have something to do with it Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted May 23, 2007 Author Report Share Posted May 23, 2007 that shouldnt be that big of an issue... you can change the idle from within the chip and the rest of the car tries to compensate for it, correct? Quote Link to comment Share on other sites More sharing options...
pwmin Posted May 23, 2007 Report Share Posted May 23, 2007 redzmonte (look on 60*) is doing this right now (95 Z34 --> 96 Z34). i will be doing it in the near future, too. Quote Link to comment Share on other sites More sharing options...

FordBoy Posted May 23, 2007 Report Share Posted May 23, 2007 the same type of stuff for OBD2 i.e harness sensors ect. Quote Link to comment Share on other sites More sharing options...
slick Posted May 23, 2007 Report Share Posted May 23, 2007 OBDII has to relearn idle also. If thats the only reason your trying to convert over, then it's worthless. Quote Link to comment Share on other sites More sharing options...
Crazy K Posted May 23, 2007 Report Share Posted May 23, 2007 I want to do this, but not badly enough to pay for it. not when I have finally found a place that can scan my car. Quote Link to comment Share on other sites More sharing options...
FordBoy Posted May 23, 2007 Report Share Posted May 23, 2007 he said he wants OBD2 because its tunable Quote Link to comment Share on other sites More sharing options...
slick Posted May 23, 2007 Report Share Posted May 23, 2007 he said he wants OBD2 because its tunable I was refering to your post and the fact that you have to do an idle relearn. We had an 02 Escalade in our install bay about a month ago, and it still needed an idle relearn. Simply switching to OBDII isn't going to fix that.

RobertISaar Posted May 23, 2007 Author Report Share Posted May 23, 2007 he said he wants OBD2 because its tunable X2 if the cost and complexity is the same, its really just an issue of finding the parts Quote Link to comment Share on other sites More sharing options...
