im after a 4x4 330 bhp chip from pj, im just curious am i limited to 330bhp? or can the chip exceed that amount?

cheers

that just means its a stage 3 chip

depending on turbo etc, could be anything between 300-350 bhp on dark greens

i just listed a power engineering stage 3 chip on ebay, only fetched £28, am gutted ( )

I have an MSD stage 3 chip I use on my car sometimes, Im forcing it to run 2 bar off boost in the midrange, and hold as much as the turbo (t34.48) can cope with doing at the top end.

Im positive that isnt what stu intended it for, but there is no Det at all and the fuelling is sensible all the way.

this is abit of topic but is the closed loop system still good at 330bhp? my cars only at 265bhp at the moment..how effecient will the closed loop be at 330 compared to 265?

The closed loop ONLY works at low boost/throttle/rpm (depends on how its mapped the exact cutover points)

So it makes no difference particuarly what power you are running as it will be on only at (for example) 4psi or less at 80% throttle or less, at 5000rpm or less.

The moment you break any of the conditions that its set for, it goes back to the normal map.


(please note im not aware of the specific criteria on stu's this is just examples to show you the point)

ok so basically cloosed loop works to set limits..say upto 4000rpm and then it reverts back to the old system?

Chip

Yes mate, thats correct.

you have a full map on there, and it decides basically wether to just use that map, or to reference the lambda sensor based on the current situation in terms of rpm/boost/tps etc

ok i get it now

thanks mate

closed loop is good

Not too sure on the closed loop thing but software I would recommend is from Ahmed Bayjoo (chip n pectal board)
