Just out of curiosity, was the question helpful?

All the work I did was write three number on my tool box............. 27mg/st, 1800psi, 12.41mpa(had to convert it grr......).

But for giggles......



Sorry, I am bored as hell today........waiting for a phone call.

I like a challenge, but that was not fair for everyone else.......Im OK with that though.....more $ for me.

That PW map looks insane!

What is the point of having close to 8ms of PW?

Don't the stock injectors empty in around 4ms?

[cleatus12r]

Doing the math on that map shows that the PCM-commanded injector pulse width exceeded the IDM's capability severely under high load/RPM situations. This thing would fart and pop terribly with any decent amount accelerator input at high RPM.

8 ms is very excessive, even with low injection pressures. However, unless something is wrong with the truck, you won't be at 100 MFD and 435 PSI of HPO. Interestingly, the IDM is capable of supplying up to 19.22 ms at 750 RPM. You certainly couldn't run that much and have a driveable truck though. Conversely, the IDM is capable of running only 3.7 ms at 3350 RPM without having issues. Another thing to keep in mind is that unless you have your MFD vs. Boost map allowing 100 anywhere, you really won't get 100 MFD commanded anyway and that last tune I showed you has 100 across the board.

Wow, I'm so lost as to what was being asked, and how Dave came to the answer... I thought I had a grasp on this stuff, but it seems I don't have a clue...

How did you guys begin to grasp all of this?

[907DAVE]

By constantly buggin Cody....

But seriously, once you get a little seat time it become a little more clear. I still do not have much of a grasp on things, lots to learn yet.

I'm going to start charging for this service.

Not really.

I'm actually trying to make screenshot movies made right now. I got a program that seems to work pretty well so I will hopefully have some decent instructional videos up here shortly. Be patient.

Man Cody.... You're the shizzle my nizzle.

I should try bugging Bill for my registration code for my free trial this week. Anyone know what info I need?

[soutthpaw]

I have an adobe program that will do instructional computer video type movies .. umm Its Adobe Captivate.... I think there is a trial on their website....
the thing that makes it so confusing is that so many maps and variables are interdependent on each others. you can't just set one variable and known you will get that as a result
