So, if I install the no.9 resistore then do the relearn procedure the IP/PMD will recognize the new resistor ?
Click to expand...
I know on mine (95 obd1) I had changed the PMD and resistor not knowing what the original resistor value was. mine didn't read it until I recently, couple months or so ago did a relearn with the laptop. when I put it in, I had used a #5. when I was finally able to get the old PMD off the IP I discovered it was a #4.

Ill open up that bin file I have and see what the table values show per each resistor and maybe post a screen shot of them. maybe it'll be helpful info for us.
 
Here are the tables for each resistor, their numbered 1-9. this is from a BPAA prom id bin file I found online that appears to be stock. I am still trying to learn this stuff so I'm not sure which other table these apply to nor what the left side of the table numbers referr to ( the 10,30,and 50 numbers) if anyone wants to help me on this, learning for me is much graciously appreciated :)

IIRC, Turbine Doc is an ex-GM engineer? Definitely knows his poop when it comes to turbos, A/R ratios, drive and compression maps, etc and how they perform/affect the 6.5 platform. He has some really good Stickies on here on turbo subjects and a couple of really good threads on turbos and fueling programs for the 6.5. A lot of his stuff on here laid the groundwork for the use and programming for the ATT turbo, CKO HX40-II turbo, the HX35/40 hybrid turbo, the HE351 turbo and the BW 200/300 series hybrid turbo.
 
IIRC, the difference between running a pump that normally had a #4 resistor and doing a relearn to run it with a #9 resistor only equates out to like a 9HP increase - not really worth the time and $ to do it.
 
Maybe with these tables and figuring them out, we can change or tweak one of them, say for the #9 resistor and make it worth while to use that resistor. just a thought lol I have read other threads on the rumor that there were other resistors beyond the #9 but I know that wasn't so much true, but making the PCM push more fuel with that resistor might be helpful for some.

of course getting the right A/F ratios is the key to complete combustion and max economy and performance. OBD1 doesn't have any sensors for us to read what A/F is where I think OBD2 does. we would need some sort of way to see what our current ratios are to determine if more or less fuel is needed on our current setups with stock turbos, ATT's and others.

I don't know how most guys here are for the expense of a upgraded turbo, but if like me where funding is holding us back but if we could take what we currently have in stock form and get the most or the best of both worlds economy and performance out of it with slight PCM tweaks, that would be awesome. plus like for my truck, it needs a little more glow time to start up in the mornings, adding a custom tweak for the glow times in the PCM rather than to deal with an ad-on manual switch to extend them, I would like.

I personally like to keep these old trucks looking as factory as possible ( love the beauty in them ). everyone's truck is different and reacts different, Ive seen others (gassers) two identical sit side by side and one would act different that the other, longer crank time, or one had more umph that the other. weird stiff I was never able to grasp my head around, but to be able to adjust the tune for the odd quirks each truck has is what I'm saying, and learn the diy approach would be icing on the cake for me!
 
The biggest problem as far as "tuning" the OBD-II systems on these beasts is that it's like trying to do brain surgery with a butcher's knife since they are IDI with fixed, low pressure pop off-style injectors and a crude advance system on the "electronic controlled" IP compared to the DI, high pressure common rail with electronically-controlled piezoelectric-actuated injectors. Not only do the hard-programmed OBD-II ECMs for these don't control many of the injection parameters that can be tuned for on DI Common Rail systems, like multiple injection events, injection pulse timings and durations in response to throttle position, etc. Former members on here, like Kojo, took tuning for these to the limits of the truck platform's capabilities, both stock and with marine injectors, differing pop pressures and utilizing non-stock turbos. In fact, it was a former member on here that developed the ATT Turbo and then the tunes to wake it up and best utilize it and the 6.5's capabilities as a unit.
 
I have heard members like Kojo did wonderful things for the obd2s and that GM had locked them down so tight where beginners like me can't poke and prod around in those computers without paying a huge penny for access. it's like how Apple keeps fighting all the "jailbreakers" out there and Tesla with the "Right to repair" your own cars. Ive heard horror stories where a Tesla owner does so much as open the hood to have a peak and their warranty is expired and Tesla won't touch it even if you pay them!

as for me, OBD2 is way beyond my skill level. Ill stick to the older electroncis and "old faithful" manual stuff for now lol.
 
there's gonna become a day where all these computer controlled vehicles will cease to function and only those manual ones will still function like the DB2's. the obd1's might survive but no one knows till it happens.

recently I found out that on-star can actually shut down your vehicle! we had a road chase here where they had a kidnapping suspect they shot dead on the freeway, but to only way they were able to catch up to them was having on-star shut the vehicle down remotely! I'm glad they got the kidnapper but the thought of big tech having ultimate "remote" control over our vehicles scares me!
 
Chrysler-Jeep (shortly after the Fiat fiasco buy out) had a couple of incidents of a Third-Party remotely hacking into Jeep vehicles through their anti-theft systems (iirc) and taking over driving and environment functions from the driver!

Can you imagine driving your new 2028 D-Max K2500 and suddenly have a strange voice come on over your On-Star system and tell you to give them the PIN to your checking account card or they'll drive you into a bridge abutment at 110mph, as your truck begins to accelerate on its own, the electronic controlled steering system begins to aim you for the shoulder and stabbing the brake pedal gets no response from the electric assist brakes?
 
Tesla already has over the air updates and is able to remotely do just about anything to your car just like cell phones. they have all your data, tracking, even cameras and audio of your every move! as they say it big brother is always watching. the rumors about smart tv's and the amazon alexia, other "smart" devices that are supposed to make your every day life easier, but under all that smoke getting blown at us is a underlining plan to gain control of our lives. in the end we'll have to go back to being cavemen and the 1800's life style to get away from it all. then at that point we'll be considered traitors to our country and terrorist for doing so!

And that is the truth.
Just watched an eyeopening series, be good for everyone to watch. It is on Amazon, the name of it is “ You Are Wanted “.
That’ll get You to thinking.
 
Truth be told, there's been several occasions I've been at home, didn't have my phone on me at the time. talking to my wife saying we needed something for the house, groceries or other wishful items and them bam! later on ill get on FB and be browsing through my feeds looking at what my friends are up to. there come several ads about the very thing I was talking about hours before!!
 
Made some progress today despite having an unusual delima coming home from work! leaving work driving slowly through the plant heading toward the main entrance, my belt decides to come off! luckily my boss was heading in and saw me sitting there and helped me out. and my truck must know me because it just happened to be the one day I didn't have my tools with me lol. got the belt back on and made it home. after letting it cool off for a while I popped the hood checking to see what might have caused it to come off and found nothing. I did go over a puddle of water just as it came off so maybe but I never saw any of the pulleys or the belt wet while trying to put it back on.

ether way while looking over things I just happened to look down between the compressor and the block and saw the vacuum line on the pump all deteriorated and was collapsing while the engine was running. replaced that with some better looking fuel line I had laying in the garage. thinking for a minuet, I reconnected the vacuum lines to the boost solenoid and to the actuator ( had connected the pump direct before our trip) cranked her back up, connected the laptop and cycled the solenoid several times by the PCM and it seemed to work just fine. Yay! apparently that collapsed hose was the problem and not my solenoid.
 
Well thats a mighty fine story of success.
How is the tensioner and pulley ? Be worth it to pull the belt, rotate the tensioner pulley, then rotate the tensioner arm through its arc, be sure it swings smooth without binding.
