I know there are a couple out there, holley, haltech,t ec 3, hks, megasquirt, which ones, if any, will work with my OBD2? What do I need to know about these things before i start shopping around for one.
what should I know about before I buy one?
im one year in and Ill give you the advice that should of been given to me but wasnt
get an fmu injecotrs and an safc. you can get pretty damn close to perfect. and it will save you a @!#$ load of pain and suffering.
and for those who say its a bad solution. go ahead and ask suncavi how well it works

You can buy a stand alone, but your best bet with odb2 is either hp tuners, or wait until i've got a solution for a swap to odb1.
Basically hptuners has full support for your odb2 i believe.
ok, if i didnt go with the stand alone, i would need a reflash, because im building a new block, and then an emanage or something of the sort, i'd rather go with the stnd alone to be completely honest,
HP tuners does not support 1996 ecu's
As far as i know you can swap a 97 ecu into your 96 or even a 98 ecu, and hp tuners will support it. If your into cash, and want stand alone, we've run a jbody off of a AEM before. OR you can look at megasquirt.
Doesn't HP have the ability to eliminate the 2nd O2 and EGR?
Thought it did. Been a while since I read your write up. Maybe it's just me but it seems like that's the best way to go. You get the best of everything. Stand alone flexibility, factory ECU functions like diagnostics and cruise control and all that... Plus I'm not sure if the stand alones would drive the factory gauges. I had brought that up not too long ago but I don't think anyone ever really cleared that up.
Ah. Somehow I knew I was right about that.
97/98 ecu swap, all i would need for that is one out of a manual transaxle 97/98 sunfire or cav? and then a reflash for the new motor?
Actuallly, 97/98 ecm and hp tuners would work. You may have to match the ecm pins on the connectors or swap them out. I will have a conversion connector list soon, the thing holding us back from building conversion connectors is the lack of a parts supplier.
I wouldn't bother switching out the ECU as long as HP has software to support it. If you did have to, get a 97 ECU. I'm guessing with a 98 you'd need the BCM and all that too since they had one. 97s didn't.
I am going to be switching to a 97 ecu as well....what I plan on doing, since the interior harnesses are the same, is just getting the engine harness and the 97 ecu.
