I am sorry if I offended anyone, I just do not understand why I am being ask my motivation on EVERYTHING, the fact is I asked for a low power tune plain and simple, I did not ask if I should use a low power tune or say I don't think a factory tune would work, so there it is the donor came with...

I don't think I said I could NOT use the stock tune. I need to put something in there because the donor has DSP-5 and I have no clue what is in there, thought I would start low and see how the cooling system/intercooler ETC, was working. I am totally mystified as to why I have to explain...

I am looking for a sub 300HP tune for my project, just want to take it slowly and see how all the bits and pieces jell

Thanks for the heads up, don't think that is going to be a problem though as I am not an idiot... also there is no way one could get confused and think a HMMWV was not running when it actually is..

Because I want to, I did not ask if I SHOULD, I asked if I COULD..the batteries are under the passenger seat and I already have primary leads going from the dash panel to the battery box in the custom body harness, it would be a very simple solution to add a start relay in the battery box that...

Nobody???

08 LMM

Well I'll be, I mentioned to the ol lady I was going to have to buy a bead roller and she said "why? you already have one" then she drug out this TEXTO (Peck Stow) beader from her side of the storage building, she has worked for years for different auctioneers and she always says when they start...

The question is does the ECM need to know you are trying to start the engine or can I abandon the stand alone harness start wires and do my own start circuit?

Would the answer be different for the intercooler lines?

Will it roll a bead in stainless? EDIT, I guess not, should have looked at JEGS first, maybe I will head down to the local machine shop and ask.

Radiator hoses, but I will probably have the same issue with the intercooling pipes.

I am wondering if silicone radiator hose will not push off of straight pipe? I am having to cut the cooling pipes to length so they do not have the bead that normally keeps the pipe from pushing off of the pipe, I am using T bolt clamps, I am not able to find rubber hoses in the configurations I...

Also I am wondering if I should replace the ECM before investing $125 in a license, it is hard to see but there are some fairly deep dents in the donor ECM from the accident, it seemed to run and function fine when it was test run. And if I replace the ECM with a used one what other than loading...

Also where is the EFI live section, I seem to not be able to find it anymore...

This one is after market and plastic, the one referenced above was a 9 blade I believe, not going to chop up a classic fan

OK THANKS for all the input, so what I guess now the question is, should I retain DSP-5 (IE how hard/expensive is a DSP-5 "tune" to create) AGAIN as I understand one tune will be or can be a "high idle" which would be good for the hydraulic winch etc. Considering all the mods made to the donor...

THANKS!! If it is locked can I flash it over with DSP-5, if not what if anything should I do with the DSP-5 hardware/wiring? With a 4.91:1 gear ratio and 37" tires I think I really do need 6th, not that I plan to blast down the highway at 85 like I do with my 08 3500HD/LMM

Well I am only a couple weeks (hopefully) to shooting some juice to my LMM re-powered Humvee, the original ECM had DSP-5 or at least a switch, I did not have EFI-live when I test fired the wrecked truck, I have some questions. 1, I understand (I could be wrong) that the ECM could be password...

I did find a 20" 11 blade fan and clutch (2000 6.5L) that could be cut down, ordered the clutch just to see if it has the same threads as the hub as I could not find that info. EDIT looks like the 6.5L fan might fit on the LMM clutch so I ordered one, also I moved the hoses around a bit and...
