its obviously a manual trans car, but you hear the engine load on something and then the turbo comes in.. before the rev limiter.

p.s. this thing is SICK FAST

2 step?

 

2-step

 

That's Chris' car... he is running the Anti-lag/Two step with the AEM (after market Plug n Play ecu). Depending on where you have it set you can build some serious boost on the line to get these heavy pigs out of the whole. That car is sick in deed he runs a stock long block and has been going 9's for sometime now. He just recently clicked off a 9.6 @ 144 to grab the title of fastest SC300 but the motor finally let go a few weeks later in some test and tuning with more boost and I believe that was after a couple of years of serious drag abuse so not bad for a stock 3.0L, huh? He is planning on building a motor over the winter to start running some serious boost. Also don't forget the SC300's are usually 150+ lbs then a Supra so not bad indeed!

Here is a quote from him on the Supraforums and a in car vid.

"Believe it or not, it was still very conservative timing for C16. I truly think that it was just the power I was making. It was in the 40's, 38psi and more timing, I was probably making over 900rw and the stock internals just didn't like."

Here is an in car vid of the pass, look how fun the car is to drive

oh btw, my FJO sensor is bad so disregard the readings.

That my friend is a 2 Step. If you have a stick you need to get one.

 

Sounds like he brings the rpm up with clutch in before he bangs the limiter.

ive had 3 different 2 steps, i know what one is.. and it is obvious in the second vid that he is laying all over one.. but watch the tach hang before it wraps over to the limiter..

thats what it was doing on the first pass when the hellacious exhaust started comming out before he got on the limiter (first vid)

i figure he could be spraying the nawaaazzzz on the line to build boost? is that even legal? lol.

 

watch the boost gauge go positive before the tach wings all the way over

i think it has a 2 stage 2 step, where it goes to one rpm level, and waits for a certain boost amount before going to the next rpm

my old accel dfi had up to 3 stages which was entire too much boost for my little tires

holeshot guy am i right no?

 

I wonder if you can use a 2 step and modify the high and low octane timing tables to reflect either 0 or negative timing in the cells where your going to be free wheeling the motor on the 2 step. Won't have a load so it will be different cells than when your on the gas in gear with a load. Basically its a 2 step with no timing.

If you can rig it to have very little to no timing and make it pig rich and i mean rich you can get some craze boost at the line.

 

Wow, he was banging that turbo hard! Definatly keeping the boost up there.

 

David that is the AEM Anti lag. It works in a combo. 2 step and dial in the timing you want retarded. Works awesome on my Supra as well. I have a new version of the LT1 LTCC by bob bailey that has this new option like the AEM. We are going to try it here in the next week or so. I will post up the result differences between a standard 2 step and combo 2 step.

So this is an off the shelf part from aem. Looks like i know what i am buying when i get the system built.

 

Comes with the AEM system. Just have to get some relay's and etc to get it operational.

 

yeah just like i said over on drag a few weeks ago... aem anti lag. On a side not, how much damage does anti lag cause to the turbo if you use it alot?

 

If im correct it works by a switch and a resistor making the computer think it is really hot coolant temp, and you can set the rev limiter, timing and fuel by coolant temp.

 

Can someone explain what a 2-Step is and how it works...? Very interested!

 

Agreed? ^^

 

my two step breaks output shafts and ring gears so i stopped using it

2 step is just a second rev limiter that you can pick what the rpm is. some you can set up to remove your choice of timing to put the ignition closer to when the exhaust valve is open. so the explosion literally comes across the turbo and out the tailpipe "bang bang"

 

damn that thing sounded like a gun
