flash

I read a truck had a cat 435 that you could flash to 500, what does it mean to flash?

it's a software program uploaded to the engine ecm.

someday, someone will be able to flash my detroit to 750hp so it can run with those big 350 cummins!

someday? that can be done any day... have the ddec IV marine software installed... all you need is a fist full of cash and a willing donor ;0)

oh, and make sure your pyro is working! very important!!!

oh yeah! forgot all about these guys, haven't been there in a long time... actually, last time I visited, they did not support ddec software, but advertised it as "coming soon".

still........ a hefty pile of cash though. i can make a s60 do a lot of singing without it... for a lot less money (but, certainly not 700 ponies, ouch! watch that pyrometer!!!).

They are shipping the S60 version now.
Hey, this new truck of mine has a 1995 11.1L that started out life as a 325/350 but seems to pull as well as a 410hp 3406E cat I was driving and as well as a trashed 12.7L 430/500hp S60 :shock: . That big S60 had no low end torque and horrible lag but this guy pulls hard down to 1100 and pretty good down to idle :shock: . I think it has had a GM boost sensor installed to reduce turbo lag (but I haven't verified yet if it is a 2-bar or 3-bar) and been turned up somehow. The max HP possible setting I've been able to verify is 365hp @ 1350 ft lbs and I've seen some mention of a 400hp setting but been unable to actually track down a 400hp spec? I need to find someone to print out the ECM info to see what settings are in there. What things do you know about to "breathe" on this motor? I'm guessing one could put in the injectors from a 12.7L but that costs as much as the Pittsburg Power Computer and doesn't give you the switchable power settings or the boost and exhaust temp gauges on that unit. This truck has 900k on it so it could have been rebuilt and at that point it would have been a free upgrade to put in the bigger injectors if the injectors were going to be changed anyways? I've also heard rumor about a marine and/or emergency version that it could be flashed to but can't find any specs on what that would give you? I'm a bit worried that my motor is turned up enough to break something or fry itself as it has no pyrometer presently. I was told that the thermostat(s) and radiator are pretty new but I seem to be running at 160 and the most I can get it up to when pulling a hill at full throttle is 175 - but I do get plenty of heat so maybe the coolant temp gauge is off? This is the best motor I've ever driven and I hope it holds together!

checking the current programmed hp is as simple as plugging in a prolink, and checking the setting. if you want to lower your hp, you can change it lower (unless of course, someone has already done that). i've seen very few short stroke S60s, usually they're not owned by the racing crowds ;0) but, if you had a 12-7, i might mention injector cal codes, a bigger restricted fitting, increase the injector height setting and valve lash... how 'bout propane fumigation!

keep one thing well in mind;

you can have 1 horsepower for 100 hours, or you can have 100 horsepower for 1 hour.

I did think propane fumigation was worth looking at - until I actually ran this motor down the road and found it was plenty strong enough already - I was going to remove the smaller of the two fuel tanks and put a propane tank in that was 1/3 the size of the main tank to run 25% propane - or maybe just a 30lb forklift tank at first to give manually controlled boost only when needed. What is "a bigger restricted fitting"? I'm suprised that increasing the injector height and/or valve lash would gain you anything - how does that get more hp? I did read a reference to injector cal codes but no expanation as to how it might affect hp - can you tell the computer that you are running smaller injectors than you really are and it will turn up the duration of the injection (I.E. up the max fuel injected) - that sounds pretty easy to do? I obviously don't want to further "breath" on this motor but I'd like to know what to look for as to what might have been already done to it. I fear I might have to pay for a Dyno run to really figure out what's up. Could even be that the motor was replaced with a 12.7L and just the old valve cover with the 325hp spec plate on it was swapped onto it? We do have one great tractor (same mfg and model) with a similar rear end ratio and a 12.7L 470hp in it that doesn't seem all that more powerful (if any) that this guy. My tranny is only rated at 1350 ft lbs and I should make sure the motor isn't above 1450 I think? Thanks!
