Newfoundland. Not the part that's connected.

I've got tunercat II software/hardware and the vdf that lets me read and flash OBDII PCM's in the 6.5 trucks.

Bought it to "tune" my 98 K2500.

No, it wasn't cheap......

 

How much doe that cost . I know buying a pretunned pcm is roughly 500$ ..

 

Just over 1100 bucks.

Then you have to figure out how to use it.

That's the real problem.

When you pay for a "tune", you're not really paying for the "tuner" to re-flash it (well, his cost in equipment is part of that) you're paying for their expertise with altering the program.

For example, do you understand any of this:





Those are some of the simpler tables. It gets much more complex.

Get it right and better running and more power can be found.

Get it wrong and a 7,000 dollar engine and 2000 dollar transmission turns into 100 dollars of scrap iron/alumium......

 

Holly eh , never knew that complex.. And if u know how to tune a 6.5 how much would u charge me if i sent my pcm out to u and put a tune similar to a kojo or heath or ssdeisel tune on it?

 

Sorry, I'm only personal use.

I don't sell my programs.

If you send me a spare (16216588), I'll flash it with a stock 98 L65 program if you want (no charge).

No guarantees it'll work (that's why I say send a spare), you pay shipping both ways.

I'll also need your vin.

I can do a couple things for you like extended torque convertor lock up and extended glow times.

One more thing; turn around time can be a couple weeks or a couple months. Free service so I get to it when I get to it.

Pretty sure I'm not breaking any forum rules as it's "no charge" service.......

 

Installed new vaccuum pump an now i have full vacuum presuure back but it smokes like 10 and i need my truck fixed , it my dd... Anyother options... Waiste gate is nice and strong again but still smokes:/

 

Can you be a little more descriptive than just "smoking"? IE: color, amount, rpm, hot, cold, etc....

First, is the wastegate closed and operating properly?

Next, pull the codes from the PCM and see what you've got.

After that you're down to:

air filter clogged

boost leak - intake gaskets, etc...

Injectors - how many miles on 'em?

Some other fueling problem


Pull the codes and go through it all very closely first. Don't start throwing parts at it hoping it will fix it.

Once again, if it worked fine before you pulled the valve covers and now it doesn't, your problem is 90% sure to be something that you removed/installed....

 

New update . Now i have no pressure at the waiste gate. At the solenoid i have full presure but after the solenoid i dont... Voltage is nice and strong at solenoid. Can the solenoid be finished and codes were p1656 and nother one but i foget .. Had to do with intake

 

P1656 - wastegate solenoid control circuit (turbo models only)

First guess: vacuum lines are backwards at solenoid.

Second guess: solenoid not working.

Betting on lines being backwards if it worked before valve cover job and not now....

Double check the vacuum pot on the turbo by routing vacuum directly from the vac pump to the turbo pot. No more smoke means problem is in the solenoid. Be careful driving it though, the wastegate will be held shut and the turbo can build up to 25 lbs of boost without regulation. This is enough to pop a head gasket. Best done only if you have a boost gauge to keep an eye on the boost and limit it with throttle to no more than 13-ish psi.

 

K found that my sensor on my upper intake wasent plugedd in now it give presuure at the waiste gate soo solenoid is good. Still smoking tho with presuure and all .. Im honestly clue less from here now ....
