Ct4 Blackwing Piggyback installed

[Tms1224]

Today I installed a piggyback (JB4) on my 4bw. So far we have basically logged stock pulls. Updated unit with integrated MAF sensor is being mailed out (as my unit for my CT5v had a satellite MAF sensor) at that point will have the ability to try and hit higher boost target and see how the car handles it, will know in about a week.
Here is a pic of the LF4 I found online, the view is from the firewall side and the 2 connections are circled... was a real b**** to get at the top one.

what data points where you able to capture? Were you able to see afr/ignition etc? Glad to see this coming as a tuning option.

Looks good, I used to run the jb4 on my 335i n54 years ago, great platform and being able to submit logs etc is nice too.

Agreed. I've run JB4's on N54's/N55 and b9 S5's. Terry is always great!

Here is an attempt to run map2 (93oct) with no maf attached.

Why no maf attached?

Why no maf attached?

In the early run of JB4's on the ct5v the MAF was a satellite (wireless not hard wired to the jb4)
He now changed it to a hardwire set up. 2 issues with the satellite.. you cant control fuel bias per rpm and the remote start would not work in cold outside temps (like below 40f). I'm currently using my ct5v jb4 he's mailing me the hardwire setup.

Sweet, can't wait to see how this continues to develop.

This is an exciting development for the Blackwing community! We look forward to working with Terry to test, validate and calibrate his product.

Installed updated board w/wired MAF ran map 1 with 93.
Car running strong and smooth pulls very good up top!
