Quick question. Other ECU's have a timing map(s) that the ecu will run off of as long as there isn't knock detected, but it won't run any higher than the table specifies, I'm assuming by simply adding higher octane that the ECU won't run higher timing than what's called for in the ecu right? I figure the car just...won't knock and the ecu will be able to run the timing that's predefined without having to pull any.
I'm not entirely familiar with BMW DME's and it's timing advance logic, one would think if you put a theoretical 200 octane in a stock car that it won't run 20* at full load just because it doesn't knock..lol

PS. I'm not sure how many are left in the batch if any. Eric & Edwin and busy processing the morning orders and I'll go take an inventory once they are caught up to see where we are at.

nice, thanks. sucks to know it's not even running optimal timing on 93.

To the contrary it's always running "optimal" timing for the conditions. Just not "maximum" timing.

a few quick questions Terry. If the jb+ is so close to the threshold that the n18 can safely run, What's different between this and the stage 1? how much more of a gain are we going to see over a JB+ when it seems that this is at the pinnacle of performance safely. Also the dyno posted on your website looks to be crank horsepower. Is that bone stock with only the JB+ set at 50%?

193whp seems a lot stock. Is that maybe with jb+ on a stock car and then the other runs are with supporting mods that's a pretty big jump in torque... who knows.

Dynos are weird and unreliable sometimes, what a person should REALLY take into consideration is the difference in power/torque not an estimation that a dyno gives you. They are good for seeing a baseline and testing whatever you did to see if it worked and what the difference was.

Don't look at the numbers guys....look at the deltas from the baseline and then the JB+ added.
Those are the gains. The numbers are inflated, so take it with a grain of salt. Also keep in mind it was using 93 octane.

Damn, I was waiting on buying one then this stupid government shut down happened. I have to save all my pennies since I am a 100% disabled veteran and my medical payments will stop on 11/1 if those fools dont get a grip.
Saw some traffic about CAI's causing lower boost and I run a DDMWorks RIS but that wasnt the culprit. Found a small leak on the hot side of the FMIC. Hose was a little crooked. Now I'm getting 13.93. My car is Happy now. Carbon cleaning this weekend followed by base dyno next week.

Yeah pretty lame how you, who has done your job and earned it, don't get paid because the boneheads in congress can't figure out how much of the money we don't have they can spend.

if you ever need to remove the JB+, make sure you use the same procedures, otherwise it might trigger a CEL.

Ya, the top of that bell curve is called MBT... It's very likely that there would be 10-15 degrees more total timing that could be added with either meth or E85. Around 30-40 more hp, that's what a E85 map would look like. Would also like to see boost to come in earlier and harder around 3k rpm. Problem is we would most likely lose transmissions and or half shafts.
