🔧 BUILD LAME Turbo V6 Camaro

[Rdrnnr]

It's not the ECM it is a PCM powertrain control module. It does not control just the engine.
It may warn you about being incompatible but I've never had a problem flashing 7440 with non 7440 bin files.
Yes I am referring to the fact that there are several different operating system updates for every year make and model vehicle. Of those updates only one or two of them maybe really well mapped out. Even if it's not the newest OS ID update from GM.

For example, in DHP, if I open up a 2004 comp G file that is the newest osid I only have access to 520 tables.
If I open up the previous OS ID number for that make and model I have access to all 630 tables.

I can open both of them in HPtuners and I only have 120 tables

0k now I know why they say you can't tune a 3800 with hp. Since you seem to know these pcms inside and out how much trouble would i have pullin the 4l60e from the 02 to put in the 98 t5 car?

Mines a 98 drive by cable. Are you telling me not to go to my 02 bird thats drive by wire then lol

Doesn't matter on our jalopies since the drive-by-wire system is basically a stand alone candy-ass self-contained system GM developed

 

[Rdrnnr]

You mightve just made my day. So I can just pull the tranny flexplate and tcm then? No issues with different pins or anything? Already plannin on takin the rear end for the 3.42s

 

[Turbocharged400sbc]

You wouldn't have any problem at all as long as you swap to an f-body automatic engine harness. Or stripped out all of the auto trans stuff and transferred it into the manual harness at the PCM connector

 

[Turbocharged400sbc]

Be aware that if you are planning on keeping the drive-by-wire that these early systems only use two sensor traces for the potentiometers and are prone to errors and glitches. All of the newer LS n gm stuff uses three traces
Keeping it drive by cable also just makes me happier

Hmm now I understand the oddity of how a certain tuner boasts about their use of the lastest OS updates... I suppose the ECM upgrade in this case will only be a hardware upgrade then unless I find out that there's a more accessible OS for my car. That's good though if it doesn't have any noise being thrown around and showing it at knock.

Since the TAC is separate from the PCM I'm guessing the same OS would work as long as I use a TPS , MAF, and IAC that play well with the hardware. Cool stuff. Thanks for the insight tonight.

 

[Turbocharged400sbc]

Just getting rid of that PCM for the 7440 PCM with the exact same OS and Bin file will probably make drastic changes to the knock you're seeing. I just spent some time trying to find the info of what number was on Dave's PCM. But I know it was nowhere near 7440 numerically. I would almost bet you he had the same Hardware number you do and you'll see the same Improvement we did.
You will have to use a drive-by cable OS for a 98 Camaro.
The operating systems do have differences with the TAC to pcm signals

 

[Turbocharged400sbc]

On the plus side the older bin files have nowhere near as many on board drive cycle tests that run in the background as the 99 and newer ones do....

 

[v6buicks]

I'm enlightened. I'll be adding the 7440 to my Camaro to-do list.

 

[Turbocharged400sbc]

By the way this is where dhp shines since you have access to any year make or model OS. Whereas hptuners makes you buy a license if you want to experiment

 

[Turbocharged400sbc]

You do know that all you really have to do is remove one of your Upstream oxygen sensors and you would be able to use a regular GTP 2 bar bin file right?

 

[v6buicks]

Geez. I wish I knew HALF of what I'm hearing tonight two years ago. Yeah, HP isn't great for everything. I'll keep my eyes open for a DHP. I'm still pissed that I passed on one that was on marketplace a few months ago.

I had no idea on the 2 bar or O2 deal. I think Brian knew that because he wanted me to get one, and I was pissed that I didn't bring mine with me. How would that work though if I have to use the F-body OS? Won't there be tables of different sizes?

Definitely keepin the drive by cable. But if the 02 harness doesn't pin the same as the 98 am I shooting myself in the foot and should just build my own tcm harness anyway or wouldn't I have to have the drive by wire and go to the 02 pcm possibly? I guess I'm just tryin to figure out possibilities before I dig in here

 

[Rdrnnr]

Keep that knowledge flowing this is gold right here

iirc the B1S2 stuff could just sit there, the pcm just wont use the inputs/control the heater with the gtp 2 bar bin file. B1S1 should be using the same pins either FWD or RWD chassis. make sure yer grabbing the newer "mini" 2 bar as it uses the same connector (just with a little key tab in a different spot ya trim with an exacto knife)
you would be able to swap back and forth on the bin files if you leave B2S2 in place. yes the VE/map table is different, its not expanded, its scale isdifferent allowing for better fueling control at lower manifold pressures

98 and 02 pcm pinouts should be nearly identical, might actually be easier to put the TPS/IAC pigtails into the DBW/auto F body harness than to add the trans stuff to the DBC F body harness.

 

[Turbocharged400sbc]

the new mini 2 bar sensors are the stock 04+ gtp maps and the cobalt/etc sc/tc 2 bar maps

 

[Turbocharged400sbc]

since ive never had the chance to test it, but you can.... check if the b1s2 heater ckt (KOEO/KOER it'll be 12v hot at the heater power wire from fusebox) recieves pcm ground with the gtp bin.....

thats how ILGPC rolls

I have a 2 bar how do I tell if its the mini. And why not just use that table and or the knock sensor parameters from the 7440? I keep gettin told ve is worthless on these and now im actually hearing somethin that makes sense to me here

 

[Turbocharged400sbc]

the mini is the same size as the naturally aspirated map sensor on both the early and late fwd cars and rear wheel drive cars.
The early Cars 2 bar map sensor was nearly three times the size and is nearly identical to the old Grand National map sensor.

 

[Rdrnnr]

Also is this the beast in question cuz I'm gonna scoop it since I gotta change rear gearing anyway

Mine looks the same as what was there or for like a 4.3. Its whatever zzp sells

 

[Turbocharged400sbc]

Ve table is used in the earlier cars in transient calculations. And in the later cars as a rationality test / fallback for a MAF failure.

I knew it. Thats why I was having issues going lean on decel terrible
