ISB Torque at Idle

[KeithW75]

I am wondering if there is any way to increase the torque that the 24v has at idle. My cousin has a '97 12v with I think it is a 350 TST plate and every time he drives mine he says that it is alot harder not to kill it. He said his can start out in 3rd with no problem where as mine you have to be really easy letting out the clutch. We both have heavier clutches than stock and I have 4. 10s and he has 3. 54s. Mine also had DDIIIs, RV ECM, and PMax2. Is he just not used to mine or has anyone else had the same experience and if so is there any way to fix it???

Thanks,
Keith

You can't expect to pop the clutch at idle and have the truck take off. Your buddy is more familiar with his particular clutch, and is better able to control takeoff at low engine speed. My guess is he'd have a hard time in a little 4-cylinder manual transmission car taking off at all, where you have no torque and have to use a bit more finesse.

If -you- aren't stalling -your- truck when taking off, I wouldn't worry about it! Increasing torque at idle may involve increasing your idle speed.

My idle speed it around 700 or 750 rpm. I thought I had heard somewhere that the 24v where harder not to kill at idle than the 12v.

Having driven a '93 12v a '96 12v and owning a '98 24v I can tell you that taking off in third with a 12v is a very possible thing to do, but in my 24v The engine bogs down to about 300-400 RPM and then, if it being bogged down quickly, it seems like the computer just gives up, and lets the truck turn off.
The 12v seem to run VERY RPM, sounds like maybe 200RPM, it's just BARELY turning over.
The 24v have a computer that actually controls idle,, if you bog the truck down, the computer fuels the engine (sometimes ALOT) and tries to bring the RPM's back up.

So.

If you were going up a hill, and neither of you touched the gas petal, The 24v ISB would reign triumphantly. If you are in first gear, and in dirt, the 24v truck would actually lose traction before the engine stalled,, compared to the 12v, it would lug lower and lower, till eventually, it turned off. (Unless the dirt was REALLY Lose).

Cool planes!

I've been hooked on R/C for the past 17 years and have just gottten into the giant scale gas stuff. I'll be entering my first IMAC contest the end of next week.
Are you ever on rconline.com?

later
