i want to purchase an MSD BTM. my question is, will i have to re-tune the fuel map i already have set on my AFC (hack)?

I just tuned about a month ago and i didnt plan on going back for a while. running around on a 4 degree retard kinda sucks. i would rather have the BTM so it adjusts the timing accordingly............my car sees about 4.5 psi daily, if that.

good question...I'd like to know this as well

BTW, what's your AFC hack settings? I have the same motor with a greddy kit.

 

i dont have them on me right now. i am at work. they vary from -26% to -41% or so.

 

well, if you are only running 4-5 psi daily, i wouldnt even retard the timing. but if you use the btm get it tuned again on a wideband dyno and you might not have to retard the timing so much and make more power

 

my car is tuned for 8psi. i was saying that daily driving i only see 4.5 psi if even that much. driving around on a 4 degree retard isnt all that great and being that i dont see 8 psi everyday its pretty worthless having it retarded so much.

The best way is probably to get your car re-tuned, but if it were me and I didn't have the money to retune it, I'd just set your timing on the dizzy back to stock. Then crank the the BTM to something from 0.5 - 0.75 degrees/psi until you can get it tuned again.

 

definately retune. you are 4 degree retarded right now, but when you return to stock timing and use btm you will not retard 4 degree until hitting 8psi at .5 degree/1lb of boost. might not hurt, but you will constantly question any little tick or rattle while boosting.

 

i dont know how you guys here detonation under boost. between the turbo spooling, motor noise, exhaust and the wastegate dumping it is hard to hear. the only way i know is if i check my plugs

 

i agree. what i'm saying that any noise will induce paranoia or constant worry. it's like 100bucks to get dyno tuned...definately worth it to not worry about having to replace anything.

 

oh im paraniod about every damn thing. i pull over on the sides of raods just to check it out. call me crazy.

thats the reason why i don't drive my car often

 

I was told, no need for BTM under 10 psi while running 93 octane. I feel like it could not hurt taking off .25 per pound for safety but they are telling me to sell it. What are your opinions? I am currently running 9-10 pounds with stock timing

 

it would be good to keep it just in case the car gets out of tune (ie: accidently get bad gas, temperature/humidity/elevation extreme change, etc). then you can take some timing out if needed.

 

keep in mind that I have my MSD6ABTM for sale. It's been on my EG for 3 years without problem. drop me an email if interested!

wow. i never heard anyone running stock timing at that much boost. i only get 91 octane out here and i am at an elevation of about 4800ft. so all that kinda changes things for me.
