Also a lot of good diesel related stuff at dieselplace.com

If you are just starting out try searching for the mcrat 20 20 tune. A lot of good intro stuff in threads related to it

Are you talking about the MAF airflow vs Voltage, or Estimated airflow vs Total fuel qty vs RPM?

Fuses x 2

When you bump up the pulse width leave the 10mm and less stock so it wont mess with your idle. If you start upping the fuel and boost you really need some gauges so you know what is going on with...

What table are you refering to on the MAF scaling? Its an 02 LB7.

I guess if no one thinks it would be a really bad idea I will try messing with it tonight and see what happens lol.

Ive been wondering if I could increase the spool up speed of the turbo by increasing the Max fuel qty vs Airmass vs RPM table to allow more fuel at lower boosts. I was thinking letting it have more...

:cheers:

Im not sure about the rest of the table. I just saw one thread, probably on diesel place, that said dont mess with the 0% tps desired torque. Im not familar with the LBZ enough to say whether or not...

Im gonna guess that your desired torque table at 0% tps is what is causing your problem. I saw a post about that, not sure where though. I would try putting your 0% throttle back to 0 and see if...

Ok I finally got a chance to sit down and play with that calculator. Awesome tool. I changed the timing around as well as the PW, backed them both down to stock at idle. I uped the max torque and...

Ok i finally got the newest version and looked at your tune. One question I have is it would seem the higher advance in the bottom right would be limited by the max timing table no? I got my specs ...

Hmm, I just tried to look at your tune and it said the index was outside the bounds of the array?

Thx for looking at things. I'm at work so I will have to wait until I get home to look at your tune. Right now I haven't noticed mine idling funny, but I know that my friends truck(LLY) does. The...

Hi,

I have been reading and looking at tunes, learning what I can about tuning diesels. I started off with the Mcrat 20/20 then modified it from looking at some other tunes. I attached my stock...

Thanks a ton for your help. I was looking at what wideband to go with and was thinking of going with the LC-1 at first but with the bad mojo Ive been reading I decided against it. Now Im looking at...

So I need to fail the MAF, get the VE tables set right with a wideband, then turn the MAF back on and calibrate it to run right? Provided there are no mechanical problems that would shoot me in the...

Ok. Also when I rev it up to about 2k it has the slight random miss and when I set the afr to 12 it clears up just like the idle. Comparing my VE to the stock file mine are higher since I added to...

The last log I did most cells were +0 to +10 range. I didnt hit all the cells becuase I was using the Pro data logging because my laptop doesnt have a battery. A mechanical issue may be my problem....

As far as I know the motor is stock. When I set the afr to 12 it will idle good down to 600 rpm. I have been tuning it with the maf plugged in. I read over some more posts and it looks like I need...

I just went out and looked at it some more. The O2s finally came up complete. I dont have a wideband, but it looks like I need to order one.

The Stock file is the tune that came with the car....

I have been trying to tune my idle. When I command the afr to be 12, the idle smooths out very nice. What would this indicate?

Also, the o2 sensor and o2 sensor heater tests show incomplete. I...

Apparently I neglected to add the files :banghead:

Hi, I got HPT a little while ago but havent had alot of time to mess with it. I have read as much I can about the basics of the program and feel less overwhelmed now lol.

I have a 98 Corvette...
