Hi Guys I just thought I'd share my experience with your'll.
I received my JB4 about 3 weeks now via Charles and I must say he's quite helpful and promt when it comes to assisting, well done on the excellent service guys.
Apon opening the package looking at the array of wires I did get overwhelmed of the install. But reading the instructions given to me by Twinz it really didn't seem all that hard. All in all the total install took me about 30 mins. Trust me guys I'm not really good with things like this but this was very easy to do with the right tools.
Ok all was fitted and time to start her up. Pushed the start button and she fired up so all was well in the install. Now time for the good stuff.
Activated the selection menu then calibrated for 135i metric. Scrolled thru the menu's to familiar with the system. Its very easy to use.
Selected shift light and set to 6600 rpm (really cool function btw) then selected Map1 13 psi which is like 0.9 bar or so. Took her out for a spin was abit confused at this point as the power was really apparent. Decided to drive to Toti for some errands and to my surprise on my way back Boom the boost started getting abit more aggressive and pulling much stronger. Pull over to the side of the road selected my gauge hijack (for those that don't no about this func it converts ur fuel gauge to a boost gauge and ur oil l temp gauge into timing or to monitor ait's) another excellent funtion.
Put the right foot down moving thru the gears the car pulled hard and smooth all the way to redline so I was pretty happy with the performance.
Later on that night I threw in some nf race 100 oct. The hooked up my lap top for some logs via the usb connection to the JB4. It was a pretty normal DBN night humid and hot as hell. Selected Map1 did 3 logs. Then stopped and selected Map2 14.5 psi which should be around 1bar boost and OMG no adaption time and the car pulled very strong of the bat. Did 3 more logs. Then tried Map7 16.5 psi. Let me just say 3rd gear wheelspin did not go well with me so only 1 log with that. Think I just need to adapt to the new found power. On a side note the fuel to boost looked pretty accurate.
Went home open up the logs and Map1 looked fine to my knowledge hitting boost targets and timing looking fine not really drops. The same for Map2. Map7 saw me hitting boost targets and also timing wasn't too bad. The stock DME looked like it was doing the job regulating the timing. Ait's on the map7 run were slightly higher but that was bcos of the 6 previous logs done without cooldown period and stock IC and of course high ambient temps.
Just to verify my findings on the logs I emailed Terry and cc'd Twins and even though it was late Twinz replied and Terry replied within 5/10 mins. Not that bad reaction time. Big ups to both of your'll. Both replies where the same 'great logs all is looking in order' the only request was for me to do more logs on Map7 as the logs looked good for such little mods or no mods on the car.
I must say I'm very satisfied with the JB and its capabilities. Its just time to add on more mods.
I met Avi333 and zeynm3 took them for a few runs, I will let them coment on the feel of the car. As I said anybody interested don't feel shy to contact me I actually love jumping in for those spirited drives.
I keep you guys updated as I do more testing and hopefully some dyno runs soon. Big thanks to Twinz and Revo for the help you guys are awesome keep up the good work.
