I know so little about EFILive its just not funny. To that end, Id like to ask you guys to look at the following four tables, and give me your opinions about what would happen if this tune was run at the strip.

i think the timing is what killed it and is the only table to be concerned about here. and yes that is a lot of fuel down low.

the only thing I would change is the lower left hand side of the PW Table I would imagine that smokes like crazy. But maybe for the track it wouldnt matter since thats more in the lower rpm's :confused: and depending on what the actual timing table looks like thats kinda high timing

Well Tom in my opinion thats a tune of fuel in the low rpms on your throttle base table. Alot of fuel in your your first tabel you posted also. To much fuel down low and with too much timing it's a recipe for bad things to happen to a stock motor. I wouldn't run that tune without changing those tables I'm talking about. Looks like a good dyno tune to get peak numbers down low though:( No real good reason to have that much going on in the low rpms unless it's on a dyno.

Im just curious and wanted some pros to give me their opinion. Thanks.

I wouldn't run it unless you want to damage your engine. There is too much timing way to soon. The amount of fuel that low would not be an advantage either. The reason EFI live is so successful is the ability to get all the right things in all the right places.

Being thats the maximum timming allowed, without seeing the actual timing table it's hard to tell where it's really at. I don't exspect Tom to post the actual table though.

You wanna bet? Seriously, which table is it? This is not a tune being sold to the public, so I have no issue whatsoever posting the info.

that timimg tabe is the max timimg the ecm will allow, its over rules all the multipliers, timing adders and timing base x tables.

33 is alot of timimng, but given the amount of pulsewtdth that puts about 55% of the injector pulse before TDC (on paper) at 3200 rpms.

but i dont know if the actual calculated timing is 33* on the timing tables

Ok, I think this is what you guys mean by the "actual timing" table, "B0910 Injection Timing Base C":

well at 2800 rpms. if you can hold 160mpa with a 3034uS pulewidth (assuming pilot is off)

ur 27.4 degres of timing will put about 53% of the injector pulse before TDC on paper.

personally i have ran tunes before with simmilar demands

That table looks fine. Your not going too see the high timing in the upper rpms and mm3. The other parameters won't allow it to occurs. I run more conservative maximum timing myself. I want it to be durable and last. Just my thinking.

The truck shifted at 3250rpm, if that matters.

I wish I understood how these tables all work together. One timing table works here, another works here, this works there, etc....:confused:

Just so you know, these are tables are from the tune I now call the "LB7RodBender", and your opinions pretty much mirror what Ive come to figure out. It was much more extreme than my normal Dmaxtuner "12.40" tune and I didnt know just how much more it was. No, its not one of Nicks tunes. It is not sold anywhere, either.
