TimB Posted September 28, 2003 Report Share Posted September 28, 2003 Trailer mod and build up about 2000RPMs Link to comment Share on other sites More sharing options...
haynss Posted September 28, 2003 Report Share Posted September 28, 2003 Trailer mod and build up about 2000RPMs so never hit the track yet, but was going in a couple weeks, hopefully will see viperkiller there as well. But Do you hold brake down while building up, kinda like power braking? thanks! Link to comment Share on other sites More sharing options...
TimB Posted September 28, 2003 Report Share Posted September 28, 2003 Yep Link to comment Share on other sites More sharing options...
dcairns Posted September 29, 2003 Report Share Posted September 29, 2003 When I was recording some 0-60 times with EFI Live, I noticed the times were better if I just mashed it, rather than doing the power braking thing. I think it gets the computer into torque managment mode from the get go, and you loose some. I also recall, before the supercharger, that my 1/4 mile time was worse when I power braked.

haynss Posted September 29, 2003 Report Share Posted September 29, 2003 hmmm, thanks dcairns. Ill try both. Link to comment Share on other sites More sharing options...
zippy Posted September 29, 2003 Report Share Posted September 29, 2003 i didn't know trailer's were a mod? and 2000rpm, did you get some special converter in yours? the couple i drove wouldn't get 2k of stall wot and held back. i tried quite a few ways and i'd say off idle or bringing it up to about 1000 to 1200 for launch. dave is correct, to much and the torque management gets ahold of you which just slow's it down after the launch.

dcairns Posted September 29, 2003 Report Share Posted September 29, 2003 With the supercharger helping, mine stalls at about 2000-2100 RPM. I didn't have EFILive when it was stock, so I don't have a log file to compare with. Look at the yellow line. Link to comment Share on other sites More sharing options...
TimB Posted September 29, 2003 Report Share Posted September 29, 2003 Thanks for the abuse zippy. I don't think I get to exactly 2000 RPM but I get close. Westers PCM seems to take care of my Torque Management issue. Link to comment Share on other sites More sharing options...
schklege Posted September 29, 2003 Report Share Posted September 29, 2003 Thanks for the abuse zippy. He can be cantankerous, but Zippy's generally a good egg: he knows his stuff. As far as launch goes, I've learned to just let 'er rip from idle. (My experience only.) Nothing else has made any difference--power braking, tow mode, etc. Link to comment Share on other sites More sharing options...
m396 #00-011 Posted September 29, 2003 Report Share Posted September 29, 2003 If you don't stall it up at the light though, you better leave on the first bulb then! Just hammering it when the light turns is going to yield terrible reaction times. Also, maybe others are different. My truck, at WOT shifts about 5800, in Haul mode, only about 5500. so, if your using Haul mode to stall up on the line, switch it out as soon as you get off the line!

zippy Posted September 29, 2003 Report Share Posted September 29, 2003 you're welcome timb. part of my comment was humor and other was just to avoid a future question. if you say you're getting a certain number, someone is likely to think there is something wrong with their truck if it doesn't. ahh, the greatness of the internet. either way, no offense implied. ;) Link to comment Share on other sites More sharing options...

Just hammering it when the light turns is going to yield terrible reaction times. No truer words have ever been spoken. They actually had to clock my first reaction time with a calendar. Never will it be revealed! Link to comment Share on other sites More sharing options...
