there are vacuum jerks. at like 10 and 0 VAC

 

Are the surges fixed yet?

 

no, not yet. But I've been driving on ghettodyne since it came out and I love it to death... those little bumps are easy to avoid, and eventually will be a problem no more.

 

Little bumps? Heh, when I was < 30% throttle hitting the 10vac jerk felt like I hit a speed bump. Not pretty at 45mph.

 

mine doesn't hit that hard, only if I directly hold it there.

 

the main one that sucks for me is 10. rarely ever notice the 0 one. seems like i'm always jerking around the 10 one when i'm just cruising.

 

hmmmmm....no P72, will ghettodyne ever be ready for the gizzer?

 

Well just put a socket in that way when you wanna re-program you just pop the chip out! Saves time and dont cost the extra 109 just like 2 bucks

 

I got the 10 and the 0 one kinda a nice little slam lol.


Also I wanted to ask a question. It seems like my boost is off maybe I am just babying it but.... I can hit 6-7 lbs of boost but i am spiking around 9. is this normal? I have no pinging or anything just a good jump on it can spike it at 9 though. I have adjusted my wastegate down alot too. much more and it will be open lol. Its kinda hard to keep it at boost unless i am really on it. (please be nice in advise this is my first turbo car.)

I have a DOHC ZC with a t25 (i see what everyone means it spins out around 6,000rpm) 2-1/4 to the cat and the baby factory crap after that. used 2in charge pipe and a new bosh BOV (its acting up but its all good) so any suggestions would be great. I also have not added datalogging yet either...

 

Two points:

First, GhD 2.2 is only really suited for SOHC, or anything smaller. xtensive has never modified GhD to handle anything other than stock SOHC fuel multipliers. If you try to tune an LS with it, you end up with GhD giving you overflow errors and crashing.

I have bypassed this by using Carsten's OBD0Edit, then pasting the maps into GhD 2.2 boost bin and setting the checksum manually. It's a bit of a PITA the first time you try to do that, and does not make for easy tuning.

Second, ShadowRex, try porting your wastegate hole a bit, and check for binding in the flapper + actuator area.
