It looks like it's getting full fuel, but why won't load go above mid 60's? Are you commanding more than 2900us, and that's a ECM limit?

It always makes me cringe to watch someone romp on it...

Nice numbers!



Older post,

Are you guys finding less drive pressure with a good tune than a stock or Smarty tune?

The only, and I mean only, time my boost was higher than drive was from...

Yeah, it would defiantly take a weaker diaphragm.. but the benefits would be good.

It is PWM, but with a standard WG on it you could flutter 12 psi of air to it all day long and the WG won't crack. It's the same WG as the 03-04's without the command valve, and they have full...

The wastegate itself is not electronic, just the solenoid. The wastegate will open at about 22-24 psi with the solenoid full open, so at lower boost levels you couldn't regulate boost like you want...

I don't see how that would make any difference on cylinder temps, it does have a 25° cooler thermostat but that's not going to make a noticeable difference in cylinder temps, which is what were...

But what is considered safe? Is 1300° safe all day long at 15° of timing, or is it safe all day long at 20° of timing, and you can go to 1350° or higher at 15° of timing?

I'm not worried...

Unless I am missing something EGT's are what we have to go by. We know it's not a true correlation to cylinder temps as timing plays a huge role in that, but we should be able to infer something in...

I was wondering if anyone has come up with a rough max EGT for "x" timing. We know a stock 04.5-07 will run 1450°+ when towing and not melt a thing, but the timing has a lot of heat rejection to the...

Which makes sense, but it just seems disproportionate to the actual time it would be needed to inject.

Why does the command duration go sky high at low load and high rpm? Is it part of the rpm limiter?

It just doesn't seem proportional, even thou flow decreases with a pressure decrease.

So you have modified your timing/duration and mm3 reference tables?

Max OE mm3 is 140 correct?

Since I am sure you are running a lot more fuel than that in reality, you just leave the OE mm3 range in and increase the duration and the ECM thinks your only injecting that amount?

That solves that I guess!

Could you move the OEM sensor pre-turbo? If so, would there be any benefit to it?

Question on dealer enabled options.

If you have certain options enabled by the dealer and then copy the stock tune, modify, and re-write will those options stay enabled?

Such as manual fast...

Great runs!

I wasn't trying to pick on your rating, just sharing some of my findings after WAY too much time researching filters.

As for the AD, if you (or anyone else reading) isn't aware the best filters...

I recently called Bosch and spoke with them about filtration. They have told me (twice, I also talked to them several years ago) that minimum filtration is 5um, and recommenced is 2um, which based on...

I know a lot of people pull their systems apart and see rust!

I think that a lot of people blame injector failures on mods/power/pressure, but lack of filtration is major. Consider how poor the...

I agree, which is why I was so disgusted with the f/w seps that were found on the AD and FASS systems 2 years ago. AD still isn't as good as stock.

Filtration is huge!

I can't help but think contaminates and pressure are the biggest killers. I also think Dodge/Cummins figured this out if you look at the rail psi map on a 5.9 vs a 6.7, and the OEM filtration went...

Thanks guys.. think it's getting a little more clear.

I guess I'm still confused about the relationship between the base table and the air density adjust tables. This is from the base table "Start of Main Injection base table. These values will then be...

So if there is a base table and 4 altitude tables, does it blend the base and appropriate altitude table?
