Someone was telling me that the jb4 doesn't control timing is this true??I thought that the jb4 and procede were very similar in the way it controls it??Explain thier map 2 and 5 auto tuning on on the jb4 vs the procede on how and what it controls????

JB4 itself has no timing control at all.

the standard jb4 doesn't control timing. you need to add on the cps module to retard timing like the procede does.

if you run meth CPS is worthless. On pump gas there's benefit to be had.

You've been mislead if you heard/read they are the same.

The JB3/JB4 has always used the DME adaptive system to set advance which generally works quite well. It's been used on 7500+ cars over the past four years for tens or hundreds of millions of combined customer driven miles. In some cases if your fuel is particularly bad or if you are trying to tune a large turbo or nitrous car it is beneficial to also use CPS offsetting to cap the maximum advance set points. For that you would get the fully user adjustable JB4 CPS module for $85. It also includes a speed limit defeat.

Translation: JB3/4 does not adjust the timing at all and it lets the DME learn by detecting knock conditions.

Where is Clap when you need him?

Oh stop. If jb users want CPS they have the option to get it. Still cheaper than a procede.

YES where is the clap when you clearly need him here lol!

got my procede from jeff@topgear ftw... best vendor on here in my opinion!

So bascially the dme has to wait for it to detect knock then pulls timing correct?

That's the way I see it too. I think the PROcede just raised its price to $945. The JB4 + CPS is only $564 and doesn't VIN lock so you can more easily resell it later if you sell the car, etc. Both tuning solutions are good and can put a big smile on your face. No need to revive the PROcede vs. JB4 timing wars of the past few years.

Timing drops aren't always knock. Problem is since the piggybacks only monitor cylinder 1 it's hard to tell. Logging ignition on all 6 cylinders with Cobb is eye opening to say the least.

So with Cobb will it advance and reatard timing on each individual cylinder based on conditions in that cylinder? Or does it set a set timing table used by all cylinders? Just curious as I ordered a AP today.

The ignition tables are fully remapped but the dme still makes cylinder specific corrections.

For what it's worth, BMS states they are working on hijacking ignition for the other cylinders so it's only a matter of time for them.

Basically if timing drops across multiple cylinders at the same time that is possible knock but drops on individual cylinders are merely corrections.

Ah I see so when we're logging and see timing drops it's not necessarily knock as it's only logging cylinder one, but with the Cobb you're able to see timing across all cylinders so you can distinguish between knock and a minor correction. Good stuff I cant wait for my AP to arrive.

Pretty much.

Ideally you don't want to see ANY dropouts though.
