I Was just wondering if anyone has run the JB4 piggy back with any of the dinan tunes. I guess specifically for the stage 2 now that dinan has one that doesnt require you to see a dinan cars dealer to install. N63
Thanks in advance.

Plenty of people have run the JB4 with Dinan tunes. Just do a log on map 0 first so we can evaluate it and then we'll go from there.

What map felt the best to you? Timing and AFR's looked fine on all of them but they target a pretty rich AFR up top.

3 feels good i also noticed rich on top end was hoping to play with map 6. But i know there is not much i can do with the n63 platform

You’ve got a problem with your boost on bank 1. It’s very low compared to bank 2.
Bank 2 is showing boost numbers upwards of 16. This is roughly correct for Map 2 although not great, but Bank 1 is way low.

I typically run Map 2 and both Banks pull 18 psi. Going to Map 6 can manage 20+ psi but requires 100+ octane.

Also note that I can not run Map 2 on pump gas (94) unless I add an octane booster.

Forgot to note that I am also running JB4 piggybacked on Dinan Stage 2.

Also, the JB4 has always been a product targeted at users that want to have a lot of control over the engine parameters. This means it is not a plug and go device, so the user will have to experiment with the device settings to find the best performance for their individual car.

For the N64 engine, octane is the most limiting factor. You need octane over 95.
Best to start at Map 4 and look at how the engine is performing before moving up to other maps.
