OBDII conversion in progress.

you're very fortunate you got everything good with the PT. Would you believe I ordered one in early november, have it in my hands, and STILL can't do shit with it?

Whats wrong with yours?

Sad to see you having these problems with DHP. When I got my PT I couldn't use it either for at least a month because once I got the hardware and could read my PCM. I had to wait for them to update their software so I could edit my file. It was the same problem you have now. Mine only got resolved quicker because the Powrtuner user base was considerably smaller then. I really don't think it's a 90 vs. 60 degree problem here. It's more like this is Charles' hobby not his bread and butter. The tuning methods described there apply for ANY GM V6 engine. So because it may be listed under "3800" doesn't mean it wouldn't apply for 3400 unless it's boost related.

But without a doubt I agree, the customer service there has really taken a dive in the last few months. It's so bad that some members decided to findout how to modify more tables in the PCM on their own because DHP was doing nothing to help their requests. The reason for this is supposedly completely new software and hardware add-ons are coming out soon. But this has been known for months with no word on a release date.

I see what your getting at and it does suck all around. I take it you have mentioned this in your trouble ticket and are asking for weekly updates on this? That's what I did. DO NOT do it in a PM, email direct to Charles or forum post. He hardly even notices them anymore. One very big problem is not to many people are into tuning OBDII 60 degree engines. So it's just not as popular compared to the 3800 crowd.

[Rhedalert]

I hear what you're saying. I have submitted several trouble tickets. I notice if I "bump" update an old trouble ticket, I usually don't get an answer for a while, so I don't know if they get notification on that. With the forum, Charles or the other staff are rarely on there, so I don't bother. I have asked questions to forum members, and I'll get info thru there.

I want nothing more than to use the product as intended and for the reason I bought it. Right now it's been just a scan tool for me.

The 94-95 manual Fbody uses the same PCM 16196397 as the 94-95 Beretta (among others) In fact I've run my car off a 94 Corsica 3.1 PCM without flashing.

So would the same PCM/harness swap be doable to convert a 3.4 to use an ODB-II PCM? Has anyone put together that list of hardware? TIA

[3400-95-Modified]

You would probably have to find a 96 f-body harness/ecm if it exists... I find it odd that you were able to run a manual car off of a ECM from a beretta corsica that never came with a manual.

As far as a beretta harness working I think that one is a shot in the dark and would result in alot of rewiring.

[FunkZ]

Here is the list of cars that I have been able to determine share the 16196397

94-95 3.4 Firebird, Camaro MT 5-speed
94-95 3.1 Grand Am, Grand Prix
94-95 3.1 Achieva, Cutlass
94-95 3.1 Beretta, Corsica
95 3.1 Lumina, Monte Carlo
94-95 3.1 Regal, Skylark, Somerset

The 94-95 Fbody 4L60E used a different PCM that wasn't shared with any other GM vehicle.

The 96+ Fbody has the 3.8 90° motor, so I doubt that would be compatible.

You're thinking the harness would not work due to lengths of wires, connectors, etc.?

[3400-95-Modified]

Yeah wire lengths is one, connector location, and how the general direction of where the wires go... But hell if you dont mind doing it then yeah you could probably use the harness if you tried hard enough. Also body harness connectors may differ alot as far as power distribution and signal in and out wires to the dash.

[FunkZ]

Just looking for options. So you were able to use the 96 PCM and harness without any cutting/splicing? Reuse any of the sensors? Is your gauge cluster controlled from the PCM or each individual sensor?

I think I'm in for a lot of work no matter what I do to try and tune this thing. Whether using the Megasquirt or going back to an ODB-I prom PCM. At some point in the future a 3400 top end might be possible, so I guess I just thought it would be better to go the ODB-II route for tuning.

[bszopi]

Here is the complete list for that PCM. This came from GMPD.

[FunkZ]

That's the same list I posted. Except you missed the Somerset.

[bszopi]

Well, GMPD doesn't list the Somerset as having it. And mine is prettier..
