JB4 Map 2, DCI, RR Catless DP's & Muffler Delete..**LOGS inside** Need comments...

seetully · 12-18-2011, 05:38 PM

Just threw my RR Catless DP's on today..did some data logging for good measure..but the car is running great, pulling hard as ever..let me know what you experts think. Im not gonna pretend to understand half this shit

your IGN adv is dropping way to low at the top of each gear for the boost your running . You either need meth/race gas or lower the boost.

You want to be at 10+ above 3-4k rpms.

Post this over on n54 tech. Terry could help will help you much better then any of us.

What octane gas are you using?

you need methanol or set to map 5 or map 1. 15+ psi is a no no with no fuel enhancement.

map 2 is typically fine with DCI and DP's and 93 octane. why can't he run it?

themyst · 12-19-2011, 12:25 PM

Your afrs are downright scary your ignition timing looks terrible and please provide a full datalog winding out the gears (at least a 3-4 shift) so we can see how the car performs under load.

You may want to invest in the CPS module from BMS for the timing drops. For $85 it's a worthwhile investment. Contact Terry for help with your afrs as that looks terrible.

its kind of a grey area, iam pretty sure map 2 is right around 14psi then it gradually gets to 15 right at the top of each gear. You could run it i guess. But the car is much
better with meth. Keeps the motor healthy and ign happy to.

At the end of the day you want ign adv to be 10 degrees or above pst 3500-4000 rpms and then start to slowly climb. If your Ign adv is bouncing around 1 of 2 things are off. Too much boost or not enough octane.

AFRs look fine for 9/16 firmware, as programmed. There is a timing drop there but it's not the end of the world. 6-7 degrees of advance at 5000rpm is where it should be for those conditions. The car is running fine. With that cold weather I'm sure it feels like a rocket.

Scratch that those top logs are worthless part throttle logs where afr is normal. Still a bit lean under WOT but that last log isn't nearly as bad.

I'd still get the CPS module to prevent the timing drops.

Does CPS work with 93 octane? I thought it was for lower octane setups.

CPS works for all fuel types. The stock timing curve is simply too aggressive for these elevated boost levels. Might not be "necessary" but your engine will surely be happier.

thanks everyone for the comments, sent the logs over to terry and he said everything is looking good for the weather im in

btw next step is def meth.. haha
