gtrs eliminator?

[nogutsnoglory]

so no install problems at all then? looking really good

4k rpm power delivery is nasty tho.. hope that improves for you.

right there still having problems with the mapping, maf readings are now normal but they said everytime they up the boost level they get power serges from the turbo any one got any ideas, they seem to think its the waste gate not set up properly kev at revo is on the case now but any suggestions would be good cheers guys!!!

N75 not controlling boost? What version do you have on it?

Possibly adjust pre-load on the actuator to stop the initial spike.

I had to use an MBC in parallel with the N75 to control the big boost spike.

Dave, i cant get my head round it, which one is right...

The more boost the actuator sees, the it then in turn opens the WG and reduces boost created?

 

[SEATCOOBER]

still have the standard n75 installed so it could be this!!! well im picking it up at 12 what ever state its in and there gonna make it drivable for me as i need it for work will suggest these things to them cheers guys!!!

The actuator opens the wastegate using boost pressure, once the spring pressure is ovecome.

My mbc is set so that boost pressure over 1.5 bar opens the wastegate. (I still get a 1.7 bar spike.)

cant revo just get rid of the n75 sigmal and i just use a mbc instead of both???

 

[PhilW]

Cool, as i thought then.

Any thoughts on what position i should run a mbc in? Paralell, before or after the N75?

The N75 is a sophisticated little valve - but it's dumb. It doesn't feed any info back to the ecu. The boost info is from the map sensor. So Revo doesn't know the N75 is being fooled / not used.

I'd suggest you try it in parallel first Phil. Once your happy - move onto mbc only or ebc.

 

[SEATCOOBER]

as in parallel i know what this means but your saying with all the same pipework as the n75 has one to actuator one to charge pipe and one to tip??? thought the mbc only came with two ports like a water tap basically!!

 

[DPJ]

In parallel:
one hose from charge pipe - tee'd into two - from there, one hose goes to N75, one to mbc.
The hose leaving the mbc joins to a tee on the N75>actuator line.

Tidy install - i like

 

[SEATCOOBER]

lol right just bin on the phone to my tuners who have just been on the phone to kev in greece lucky boy but still cant get away from it in another country lol, they said you can bin off the n75 and leave it electrically connected block up hole on tip and just use the mbc in its place!!!

 

[SEATCOOBER]

also can someone explain knock correction as im getting about 12% and being told this is massively high its meant to be around 2%, but could my turbo serges be causing this?
