Boost question?

Hello, I just have a quick question. I have a 92 mr2 turbo with a greddy profec b boost controller. When I set my boost, I was in 3rd and also did some runs in 4th gear, I finally fixed the problem I was having, but now when I start off from 1st, the boost only reaches 0.6bar, 2nd gear hits 0.8bar and from 3rd on, the boost is dead at 1.0bar. Is this expected from the ct26? I know it won't hit max boost levels in first gear, but should there be such a jump between gears. Thanks in advance for replies. :smokin:

any ideas?

... just one of the reasons I do not like the GReddy BC. The Blitz has no "learning modes" to set boost in.

I suspect that BC is limiting you.

So the Greddy Profec B has a "learning mode"? I wasn't aware of this. :confused:

Isn't that how you are setting boost in 3rd gear?

**maybe I am wrong. I have a PRofecB years ago (1996!) ... and I recall having to do runs in 3rd gear so that it could "learn" the boost curve.

I wasn't told anything about that. I do the runs in 3rd and 4th due to the added load on the engine as apposed to the lack of load in lower gears. Tuning boost in higher gears, I always thought was the most accurate way to do it. But if I am going about this the wrog way, just let me know. Thanks

You are correct ... setting boost in 3rd or 4th is best.

What do you have to do on the Profec to set boost?

It has 2 dials, 1 for low boost, 1 for high boost. You just push it in so it can be turned to set lower/higher boost. I have the low boost setting set to .5bar. A high boost setting of 1.0bar in 3rd-5th gears. 1st only goes to like .5 or .6 bar, and 2nd goes to around .6 or .7-ish. Still pulls good, but I would like to hit the set boost level in all gears even of it is just for a second! Thanks

Anybody know about this controller?!?

I think that I may have the same contoller as you do. The only thing mine has different from yours is a "Balance" dial. Im still trying to figure out how to set it.

Any other ideas on this controller? BTW I do have 3 dials, just forgot about the mild/sharp dial! lol. Thanks for all replies.
