JB4 VS MHD OTS my experience

[Cfdproductions]

Car is a 6mt with the basics intake, dp, charge pipe upgrades. Been working with Jesse for the past year making the car quicker and quicker on map 6 E40. Finally got it down to a 7.21 100-200kph right before the clutch gave up on me. Put a clutch in it over the winter and picked up MHD this past week. Flashed the E40 tune and went out for a few pulls. Car went 7.29 100-200kph, I am shocked to see just how close the JB4 got me to the performance of the MHD OTS map. That being said it was quite a bit better DA on the day that I ran the JB4 but also my clutch was starting to slip on that pull. Either way I am just pointing out that when full sent the JB4 is a viable option and really can hold its own with the OTS flash tunes.

I'll be interested to see what an e40 MHD custom tune will give you and how much higher the ceiling can be.

Very very soon

Do you have logs for both? I would be curious to compare the two.

I have logs what values did you want to know about

if we don’t that would be pathetic

Do you have WOT logs of both you can upload to Datazap?

I do but I’m not on a computer to do it

I went from a JB+ on 98RON to a stage 2 MHD OTS tune (also on 98RON) and while the improvement is there, it wasn't really earth shattering. The JB+ recorded 310kw/550nm (with a stock DP) and with a sports cat, it felt even better, and I'd estimate by least 10kw. Rumour is the stage 2 OTS tune (with a sports cat) should pull around 360kw, so there is improvement you can feel but its incremental.

More than an improvement in power, having an ECU tune just feels better (phsycologically). The piggybacks give off the air of a cheap hack, by comparison.
