i'm lookin for a stand alone boost controller. for my cossie.

i want a contoller i can press in a set boost level, (say 30 psi) and for the boost to be 30psi from 4k rpm in 1st gear, to 7.7k rpm in top gear.


wots good?

 

i dont like boost controllers myself,,, i believe that they are taking away one major factor of engine control away from the ecu?

would you run a seperate ingition controller?

 

Turbosmart e-boost.

 

not really as at mo i'm only usin a actuater to controll boost, the only problem is it runs more boost in higher gears.(due to more load).

the map sensor controlls fuelin to boost, so runnin a boost controller, as long as the ecu's mapped to run sed boost, will not have a problem.

but if the controller fails, its very much like if a airinj fails, or actuater pipe fails.

 

the apexi avc-r is very good althought it can be tricky to set up.

it allows you to set boost by rpm, gear etc. has loads of other features as well.

see here for more info http://www.apexi-usa.com/product_ele...=200&pageNum=1

 

who sells the apexi stuff in the uk?

 

loads of places. just look in the back of one of the jap magazines or ask steve n as he will probably know who does the best price in the uk!

 

the thing about aprxi is its designed to run on a jap ecu as they have outputs for it


speak to RSNISSAN as hes a genuis with apexi's as he had one in his old gtir and hes fitted a few for others too

 

i agree with you,,,, but when the ecu wants to run slightly less boost,, it cant

 

can't you use the amal valve output to an input on a the apexi (if it has some "extra" inputs)

 

turbo smart e-boost! adjustable sensitivity, gate control , 3 boost set points which you can set, overboost setting , peak boost recall etc

 

An interesting and informative discussion on boost control here:

That may not actually be possible at all, ie the rate the car accelerates in 1st might mean the turbo cant physcially spool up quick enough to keep with the demands you are making of it.

But TBH for what you want, just use an MBC, for just one set value they are great and they eliminate wastegate creep more or less totally, which will make a massive difference to 1st gear boost.

 

i use an a'pexi avc-r and find it excellent, need to read the manual and it all becomes clear. Will work with ANY ecu as it ONLY controls boost. to have gear selective boost you will need a compatible speed sensor, normally from a jap car ? i am going to use a custom one which also drive the stack speedo
