According to Mike/Terry, the JB3 runs much less timing and it is readily apparent in the BT logs. Yet Shiv indicates the JB3 does not monitor of A/F ratios, timing/knock, engine temps, etc.
Shiv and/or Mike/Terry - Please answer the following to help me make a purchase decision:
1. Even if the JB3 does not monitor those critical functions, doe the JB3 still pull timing? If so, does it do this purely based on the level of boost? If it doesn't pull timing based on boost, what is used to calculate the amount of timing retard to apply?

The JB3 cannot pull any timing. In fact, all timing retard you log is from the factory DME sensing knock and reacting accordingly. It was discovered via independant test (over a year ago) that despite the claims by BMS, the JB3 has no CPS offsetting feature. Which means NO ABILITY to change DME timing targets.

2. Shiv - Assuming the JB3 is pulling timing dependant on boost, while not as sophisticated as what your auto tune is doing, in your opinion, is this still a reasonable approach (assuming people are not pushing their cars to the ragged edge)? If not, why? Would there be a relatively safe level of max boost where boost dependent timing controls would be a reasonable approach?

There is no assuming. The JB3 doesn't pull timing dependent on boost or otherwise. The only form of knock control is the factory knock sensor. At this point, BMS won't/can't even deny this. Despite their initial claims otherwise.

3. Mike/Terry - You've stated previously in this thread that the Procede V4 does absolutely the same thing with timing that the JB3 does and this is confirmed in the logs. Shiv indicates the logs do not accurately record exactly what the Procede is doing (there's an inference that additional timing is being pulled in a manner that cannot be logged as a way to protect his technology). Mike/Terry - Can this be factually disproved by you? (Shiv, I'm not asking you to share how this is done as it would defeat the purpose of hiding it in the first place.) Is there a way timing can be accurately measured in another method that can validate or disprove Shiv's claim that the Procede V4 is indeed adjusting timing in a different manner than the JB3?

All you need is a
scope to compare the original and the modified Crank angle sensor waveform to confirm that the Procede retards timing. Any suggestion from Mike/Terry that the Procede does the same thing as the JB3 is a blatant lie and an attempt to save a rapidly sinking ship. The fact that some people still think the Jb3 has any form of timing control is a testament to false marketing and misinformation.
