Help tuning what on the e- boost 2, is it boost levels , sensitivity,gate pressure. Be more specific and I can read through my directions and see if I can help.
sorry, guys, didn't get a chance to get back online last night.
Anyway, it's nothing that's in the directions. I understand all the basics, and have it working correctly. And yeah, that OBP bit me in the ass on the last dyno....
anyway, here's what I'm trying to fix. On my low-boost setting, for instance, I hit 15 psi, drop to 14.4 or so, the start climbing back up to 16.2 or so. The little spike doesn't really bother me, but I'd like to keep it from climbing so much higher afterwards.
My sensitivity is set to 10, my gate pressure is at 15.
you should have the gp lower than what boost you want, so if your looking for 15psi the gp should be a couple below(normally so it doesnt spike), your sensitivity may be low and the combonation of the 2 may be causing the issue
basically you set the gp low and work up till it spikes too much, then fine tune w/ sensativity

Ok, question. I have an original eBoost, rather than an eBoost2. Not sure if they're different, but on mine the boost and gate pressure are a number between 1 and 99, not directly related to psi or kpa or such.
Is yours the same? If so, then the gate pressure should be set to a number close to the boost, correct? i.e. - if trying to hold 20 psi, my boost number is ~50. Should the gate pressure be the same?

On my eboost 2, the 1-99 number is the boost and 50 should be spiking about 19.As stated above the gate pressure is raised until there is a spike higher than desired and then lowered until the correct spike is obtained.Then the gate pressure is right.But the sensitivity has alot to do with the way that the boost comes on too,If it is to low it takes to long to achieve desired boost, to high and it will spike too much. That boost controller is really advanced it just takes a long time and alot of tuning to get it right.

If you don't mind me asking, what turbo do you have, and what numbers do you have on your eBoost for boost / gate pressure / sensitivity?
I'm glad to know the numbering is the same on the eBoost2, so it'll make this easier to correlate to my original eBoost.
I have a 50 trim spiking and holding 20 lbs. My boost number is 55, sensitivity is 30, and my gate pressure is I think 14.5. But I had problems tuning mine also there is just alot of different things that have to be dead on for everything else to be right . Just takes time ,good luck.
eboost 2 has 3 settings per boost setting, sp, gp and sn
sp is the 1-99 number that correlates to a boost level depending on the spring used in the wastegate(assuming yours is external?what spring?)
the gp basically start low like 10psi and see what boost level you get then fine tune from there, smaller gate size will need a couple less than the actual psi so it dosent spike bad, so thats when it starts opening the gate. I left mine at the default 20 and worked fine for low boost (14-15psi, which is gp of 40-44 cant rember, this is w/ a 7# spring, tial 38mm gate, SC6152E turbo, auto)
then sn is sensativity to fine tune from there, I havent messed w/ mine too much because I'm switching over to using rpm based setup but using the speed sensor to have speed based boost for traction control, basically the speed sensor signal wired to the rpm input so every 5-10 mph you can up the boost.

yep sp is the pressure setting mine is at 66
gp is in psi (if you put it in psi) you can put it higner if you want it to spike intentionnaly
sn for me have always been at 1, on the stock wg and now on external wg
if i try to put it higner it go up and down all the time(the pressure)
there is lots of neet stuff in that e-boost2
i use the alarm to do like a shift light, then it is more like a shift buzzer
for me i use a tps switch and 2 magnetic switch in the shifter
so i use 4 different setting
-normal driving
-wot in 1 gear
-wot in 2 gear
-wot in 3,4,5 gear
