i know there are some tricks people use
i have tried the IAT table switch and undesirable effects with that
i have heard of another one by grounding out the 2-3 noid while selecting 3 and you can brake stand in 3rd and bump the switch and go back to first when you launch and some other ones for traction control?

anyone care to share some tricks?

i cant seem to get the force 3rd to work

if maybe we could spark up some conversation or help each other out and share some knowledge that would be awesome haha

cutting a 1.81 currently at 135
i dont want to do anything crazy but i would like to cut down that short time so i can really improve the ET

**********

Edit. working!
here is my diagram


i needed to disable the following codes so the computer would not go into limp mode

video of switch mod working great, track too cold too hook

thats 4600 and 14psi~ on the foot brake with no wheel speed

on a car that has trouble getting 3000 and 2psi

The higher gears, better brakes, or trans brake are prob going to be the only option to make it 60' hard with that small of an engine. Have you tried going the opposite way and adding timing during spool and in the lower boost ranges? When does the water/meth start spraying?

IAT trick works awesome for me. What didnt you like about it?

denmah

iTrader: (2)

yeah it doesnt like it when i move it around while brake standing it up
water meth comes on around 10psi

i would really like to try the high gear mod, just doesnt seem to be working form me

how do you have it setup? mine makes the car super rich and it doesnt want to brake stand, if i lean that part of the table out, when i go back to the iat turned on, the car falls on its face bad worse than if i just gas it and let it take off and spool on its own

Have you thought about using a 2 step? Ive seen a couple auto guys use them that dont have a tbrake. The best way to set it up is activate it off a manual switch then through the brake switch. So basically, you do your burn out, get up to the line, flip the switch, then footbrake it like you normally would. Youll have to setup the limiter and timing retard to whatever works best to make boost on your car, but it should work.

i dont mean to be difficult but i would like to do it with no other additions to the stock computer, i am sure there are a ton of ways to do it just people not sharing.

i got a tip on how to force 3rd with a switch while brake standing first, this isnt working for me though

i did IAT timing retard but it totally goofs the Air fuel and makes the car die after the switch is released for about 100ft (running super lean, because the timing retard makes it run fat, and if you dont pull the fuel it just bogs on fuel)

i am aware i can put in a MSD/LPE 2 step box, wich kida sucks anyway they are just stutter boxes,

i have also grafted the Microsquirt into the stock harness on another car to use the ALS system, but i am sure there is some way to hit these goals without the boxes, just some tricks

i got more information on wiring a 2 pole relay to the 2-3 solenoid to force high gear when you have high gear selected.

if this works out ill do a whole writeup on it

I don't know about the 80e but they used to grind a flat on the manual valve in a 2004r so it whould go into two gears when it was put manually in first this whould lock the trans up so you could build all the boost you wanted then to launch you whould just push the shifter into 2nd and it whould launch and shift by itself.

even if you could get it to go into 2nd like a limp home mode to build boost that whould help

yenkomike

iTrader: (2)

what happens if you disable first noid will it default to 2nd?

denmah

iTrader: (2)

by selecting D3, and then cutting and grounding pin B
it will force the highest gear, since manually in 3, it wont hit 4th, it will only be able to fill 3rd, from there you can brake stand up against a the trans locked in third gear, wich has considerably less mechanical advantage over the tire and brakes etc.

should be able to get to complete high stall speed easily or at least find the max

then you flip the switch, and lift off the brake, then you are instantly back in first gear and it will shift normally thru the gears, with more brake stand hopefully.

Interested to see the results. I tried the iat tricker, and it worked not so well for me. Pulled enough timing to keep from pushing through the brakes and it built a little more boost, but their is a lag when switching iats.

denmah

iTrader: (2)

yep i did not like the IAT switching at all,

im working till midnight tonight but ill be on this tomorrow

Hmm weird. Mine also goes pig rich but man does it do the trick with spooling on the footbrake. No issues letting off and launching either. Interesting idea on the 3rd gear hold.

How much timing do you have yours pulling?

denmah

iTrader: (2)

ok so i have this working now...

Could you uses some of the Torque Management tables to retard the timing while foot braking? You could reduce the max torque in the P/N row in the RPM vs. Gear table to retard the timing then fool the computer into thinking you are in P/N while on the brake. It would be kind of a Ghetto launch control to get the turbo spooled up. You could also play with some other parts of the Torque management for traction control.

i can brake stand 3800 without spinning the street tires on the smooth concrete in my garage, didnt try for more yet but that should help leave at the track hahah

before this would push in first gear at 2200-2300 in my garage

So what exactly are you doing?

Flipping a switch to force third gear to load the converter easier without pushing the tire or car
