Default Installing E-Boost2--any tips?

Looks pretty straight forward, but the less time I spend doing full boost runs down the highway the better.

1. Set the Boost set point (1-99). They have a chart for a 7psi internal wg, but I have a 1 bar external. I guess I'll start with 1 and work my way up.

2. Gate Press. Reads like I just keep upping it until it spikes, then back off a tad.

3. Sensitivity. Not sure on this one

4. RPM set point: Dunno if I will need this. I think I'll save this for dyno tuning.

Any tips before I blast down the street?

1. Start at 0 and work your way up.
2. If you have the controller installed "internal WG" style then lower "Gate Pressure" settings have faster boost response but if you have it setup "External or dual port" then the higher the setting the faster the boost response. In either case I usually set this up about 3-4 psi less than my WG spring.
3. Start at 0, adjust the above first and then increase this if required. A range of 5-10 usually works well with external gates set to 1 bar.
4. I personally don't use this feature so you're on your own here.

Thanks,
Phil

I run a two port set-up on an external gate.

Currently using a sensitivity of 30 with a 14 psi WG spring.

Stronger WG spring lowers your boost setting. Currently 58 gives me 22-23 psi of boost. That gives you a approximation, don't use that setting, work your way up.

Gate pressure is currently at 10 psi. Too high will cause spiking. Haven't had much luck tuning this better than the sensitivity (gain) setting takes care of.

I used a COR (correction) setting to compensate for loss of boost at high RPM, this was with a 7 psi spring. After moving to a 14 psi spring, I have not needed it.

Make sure you tap the right RPM/tachometer wire off of the ECU.

Thanks bboy. Regarding the tach wire. I tapped it and it showed up in the eboost, but it made my stock tach go out. Removed it and stock tach came back. I'm running without it now.
