Thanks for sending the picts Jim! I agree that the BTC looks like a quality piece. Too bad I wasn't warned it was coming out because I bought the MSD6BTM back in April. http://www.hostboard.com/ubb/frown.gif Oh well, I hope you and rjaffey give us the pros and cons of this new device when you put it through race conditions at the track!

Hey VtecNOGeek...
Do you think you could combine ALL FOUR threads concerning the BTC... I believe it would make it a lot easier to follow.
Just a thought...

THIS IS JSUT TO CONTROL THE TIMMING , RIGHT?
NTH TO DO WITH DETONATION, RIGHT?
JUST WANTED TO KNOW HOW WOULD AFFECT THE DETONATION SINCE THAT IS POSSIBLE TO RUN AT 16BTDC.
THANKS

What's the difference between this and the MSD 6BTM ?

I think you get it painted a neat black color with a cool JR logo!
-
recently, I also heard that it adds timing off boost. is this true? that would be cool. otherwise, bleh.

Yes, the rumors are true:
The BTC is NOT a re-badged MSD BTM. It is a re-mapped ECU and a Boost sensitive Timing Retard Control all wrapped up in one nice little package... there is NOT any type of Ignition amplification here.
The timing and fuel curves have been optimized: the timing is slightly advanced from idle to 3000; then progressively retarded from 3000 to 5000; then barely advanced again from 5500 to redline. The BTM knob is a "Click" type control with 21 positions (0 to 2' in 1/10th degree increments). VERY PRECISE.

Jim: Can you tell us what it does to the fuel curve?
Also, how is the retard setting used? Is it a factor used for both raising and lowering timing and applied all the time? Or does it just determine how much retarding happens after 3000? Does it affect the timing advance after 5K?
Thanks,
Greg

The BTC was desingned with the Honda timing curve in mind, as the MSD BTM is a universal piece, and the BTC has more accurate dial in measurements...
Someone correct me if I am wrong...

I'm just curious but how many hp will the JR BTC will give you? Also how many MPG fuel saved?
-
I'm thinking that I'm going to wait and see how these work out for people... Guess I'll miss the good price Jim has going right now... I'm more interested to see how it works for the 8psi crowd with stock injectors... It's time to buy either this or the Zdyne and be done with it! Thing is, think I'll have to do the injectors before its over anyway...

My BTC is in and will be installed next week. I have a stock 96 GSR except for 6 PSI JRSC, HO fuel pump and intake. Does anyone have a similar setup that has installed this? What are the recommened settings in terms of base timing and amount of retard or did you use different settings?
