I'm using it because I had already made one up myself prior to the general availability of flash tunes and it effectively enables me to adjust the torque/load/boost targets on the OTS tunes.
e.g. the MHD Stage 1 E30 map has a base torque/load target that typically generates 16 - 17 PSI.
Having a JB+ type device connected to the charge pipe sensor allows incremental increases in boost e.g. I'm currently running 18 - 19 PSI on that tune and ran another 100 - 200 in 7.3 seconds this morning.
JB+ and similar do mess with the reported boost, load and torque data coming via the MHD logging software so I'm rescaling boost based on MAP volts data in my logs. The 100 - 200 times and Virtual Dyno results prove the benefit.
Using it on the car when it was stock I got a 12.49@114MPH with a 2.07 60ft, could have been an 11.9 with the Hoosiers and a 1.77 60ft
My DIY version has a resistor and a potentiometer (creates an adjustable resistor) in a little black box that tucks under the engine cover. I sourced the male and female connector plugs, M & F contacts and wire seals from companies in Germany and USA. All up about $20 - $30 in parts and it was an interesting side project. |
Do you think I could run it with BM3 Stg 2 E30 OTS? I would be happy to get the parts list from you to make my own.
