Maybe Satish would share some of the finer points of the installation procedure of his electronic 1st gear start?
Also, how does the ASR work without being defeated when using first gear start?

1st gear start reads the speed pulses from the speedometer circuitry. When speeds fall below 2 mph, the module sends 12VDC to the kickdown solenoid via the "B" switch. At speeds greater than 6mph, 12VDC is released from the solenoid and pedal pressure will determine how long the car remains in 1st gear (just like any other gear).
Installation involves 4 wires total: 1 = ground 2 = kickdown 3 = 12VDC+ 4 = speedometer pulse The module is solid state, small, and works great! No modifications to the transmission necessary and the circuit may be disrupted by interrupting the power source to the unit (therefore reverting to a 2nd gear takeoff). ASR may be more active with 1st gear starts just because there's more chance of wheelspin in 1st gear. Obviously 1st gear start combined with a proper ASR defeat switch is the best thing to do. In terms of bang for the buck with virtually NO possible harm to the car, this duo is the way to go. Best Regards, Satish 1989 500SEC-32V 1999 E430 Sport |

So is the ASR Defeat switch merely a switch that enables the "SNOW" feature at all times (removes speed sensor from the ASR SNOW OFF equation), or is there more circuitry involved?
If a 1st gear start with the 2.87 diff is too much, I guess I won't go to a 3.07. However, is there such thing as a 2.87 limited-slip ASR diff? TIA, :-) neil 1988 360TE AMGE 1993 500E (Barney) PS: Satish, did I see a "1999 E430 Sport" in your signature line? That sounds too "simple" for your tastes. Is a Brabus 5.8L engine transplant in the future? |

I just gotta say, Scott, your car is BEAUTIFUL! Keep the shiny side up, eh!

Neil,
Here's a pic of the ASR defeat mod from Renntech: The kit comes with (1) an instruction sheet, (2)an "ASR Off" switch, (3) an ASR harness which connects to the ASR computer control module found in the engine bay, (4)a switch connector harness which connects to the switch and to the (5)control box. It does tap into the snowchains switch though... Hope that helps.

Thanks.
What we need to see, is what's in the box, and what connects where. Care to open up that "black box"? Take care, :-) neil |

Refer to above post.
The ASR switch (2) is connected by the harness (4) to the control box (5) which is in turn connected by harness (3) to the ASR computer. The black box is sealed, sorry.

What does Renntech get for that setup? I have heard some big dollar figures to defeat a 10 year old setup. Someone has to have found a way to feed the proper voltage inputs into the OBC to deactivate the ASR without causing the system to go into limp in mode.
Does jumping the 2 wires at the OBC or disconnecting the front sensors give you a one time only launch without losing performance? I would love to feel this car go around a corner knowing how it will come out. My '01 Vette had a refined system to correct for high speed control problems by activating a brake and retarding timing but it was defeatable. Something tells me that someone wil be unsealing one of those "stealth" boxes in the near future. This has to be a mod. that can be made affordable or at least one that I can justifiy the cost of.

Renntech wants $985 for it.
I was looking around for alternatives but couldn't find any. Although I agree it's quite pricey for what it ultimately does, which is turn asr off, there doesn't seem to be a cheap alternative. Renntech put in a lot of R&D into this and came up with something that works. If it were and easy mod, I guess a lot of the shops would have it figured out by now. Some things you just gotta pay for I guess...

I have had the PAD switch for 6 months. Cost $485. Works great. My car just ups and goes, on the track it is absolutely priceless, you can hold the car through a corner on the throttle, without ASR taking the power away.
With 275 Pilot Sports you can use all the power and all the grip. David Hendy '92 500E |

What mistake?
[I deleted my correction too! ]

Was very nice of you to point that out. I will return to literacy classes next week
I deleted my mistake. Does that excuse my mistake?

I tried...
Neil,
I was inspecting the box again tonight and noticed it was not sealed. There were scews at the bottom. I opened the box up and found what seemed to be a thick copper or other metal (it seems) circuit board, 3 rectangular ICs and ten wires going out through a wire loom. Unfortunately, Renntech sprayed everything with black paint, I believe precisely to disguise/hide what components were used. I didn't mess with it any further... Sorry bout that...
