greddy boost controller... will it work?

Will this electronic boost controller work with my mini turbo set up?
Bearing in mind i don't have the ECU. Its quite pricey but looks really cool.

i did a search and found this:

last post 2004 so will be interesting to see peoples opinions 5 years later

profec B spec II will work fine in a turbomini, shame you lot dont have electric speedo's and rpm outputs from an ecu, the gear dependant boost controll in the apexi avcr is awesome :)

pretty simple tbo, the avcr has a road speed and rpm input, from this it learns up to 5 gears. (as these are distinct ratios)

you start by setting your desired boost, say 1 bar, which requires 50% solenoid duty.(theis is an example to illustrate)
do a few pulls and the avcr learns the cars boost profile, i.e. it optimises the solenoid duty to give you the target boost as fast as possible and as stable as possible.

you can then edit this as a kind of "duty curve" so you can make it spike, or you can make it come in very softly, or if your car is prone to det up the top as the turbo is running out of puff, you can back off the duty up top so it makes less boost etcetc.

once thats done you can then set a kind of correction facotr for each gear, this is a percentage of the origional duty, allowing you to pull the boost down in lower gears, ir if your eager, give you an extra kick in top gear! can spend alot of time fiddling with it. has the usual scramble boost feature too :)

they are the b*llocks, this is what i've got in the mini, omex200 output rpm into this. correction factors etc are good. No boost spikes either!

The Greddy unit works very well..although its getting pricier I see !!

Gizzmo make some decent stuff, and are a lot cheaper. Google them.

The Turbosmart E-boost does in gear etc etc, and is much easier to use than the AVCR.

I hate those AVCR's with a passion, plus they look really naff.

E-Boost does it all from a single guage style unit.

For a speedo take off...you can buy in-line pulse adaptors for the cable....most seem to be for Rally trip computers. No reason why they couldnt be used for a electronic speed reference for boost control too

Going rate for a new avcr is £250, but each to there own :) find them to be one of the easiest controllers to set up! but iv done more of them than anything else so guess its just personal preference/familiarity for me.

e-01 is only of any real use over a profec b spec II if you have an e-manage blue to utilise all its features, outside that its jsut a profec B with a big display, imho ofcource!

Cheers guys that really helpful. What about turbo timers i was looking at an APEXi one on ebay. its about the size of a pencil. Anyone got a turbo timer on theres?

i have, but stil havn't managed to get it to work, mines an old school blitz one, but to be honest my turbo is now water nd oil cooled so i just lave the car running for a few minutes when i stop.

Paul,

I'd try the boost controller in the MS code first and see how that goes. It has a PID control code so it should give pretty good results but it won't be with respect to speed or gear.

If it doesn't work well you can always go with the avcr.

Gizzmo ones....

ive only used the cheaper one...seemed to work just fine, and is a nice compact unit.

Thanks Denis.

I can make a 0-5v square wave with a hall sensor, so I think I'll give it a go.

Presumably the TPS signal can be taken of the signal wire to the MS?

yeah :) its a very high impedance input, wont affect the reading as seen by the MS.
