hey guys this question may be much more simpler then i am understanding, but here goes (flame suit on). Ok heres the scenario: you build your forced induction motor, have it tuned for say 300hp @ 10psi using a programable ecu (hondata)....(this is for examples sake) you then buy a boost controller and set it to 10% boost in first gear, 30% in second, 60% in third, 80% in fourth and 100% in fifth. (its my understanding you can do this to combat excessive power and wheelspin at launch, if it doesn't work like that please explain.) My question is, after the car being tuned and making 300 hp, wouldn't you have to get it retuned for each gear after messing with the boost controller, or would your tune be fine to run 10% (1psi) boost in first gear 30%(3psi) second gear and so on....am i reading too much into this. Thanks guys.

 

if the car is properly tuned up to 10psi you should be able to safely run any amount of boost below what it is tuned for.

 

awesome, thanks, so i WAS infact reading too much into it.

That said, I remember a post not to long ago talking about this and there was mention by a couple of people about needing to touch up the tune on some load cells when you want to change boost on the fly... something relating to the transition into boost differing at various boost levels. Someone correct me or elaborate on this if I am wrong or whatnot but I could of swore I read that here... will try to find the thread but agian I am no tuner.

EDIT: I cannot find it... this forum moves to fast... dont listen to me. I dont want to tell you something without having the information for you to read I am recalling.

Any GOOD tuner will tune the complete map up to the desired boost level. If the tuner simply sets the boost to 10psi and tunes only at that load, then you could have a problem at lower boost levels.

thanks for the replys, so basically the tuner is supposed to tune at every level (1-10psi in the case of the example) up to your desired cut off point, or whatever the motor can handle....good to know, sorry if it was not such a great question i was a little confused but the replies definately cleared things up and i understand whats going on now. Honda tech is definately an extreemly valuable resource, really what im trying to do is find out as much as i can before building the motor and having it tuned so im not oblivious to whats going on.

They will tune the vacuum (~21 in/hg to ~1psi) too. The car should drive smooth with just more power than stock

 

i can't say thank you enough.....i wish there was some way i could learn to tune myself im very interested in doing that as a full time job....

It is a great start. If you get your car tuned, ask your tuner about things you do not understand, they should answer them with no problems.

efi101 is definately a great start if you want to learn about tuning

 

id love to attend the efi101 but it seems to be located in cali and i live in florida.....however you have given me some food for thought, i am going to check out possible tuning schools in the area this weekend and take a few courses, maybe even get certified as a tuner, (gotta finish up my last year at university first).....the prices are very reasonable on the provided link, hopefully they may be comparible in florida. Ok lol lemme let this thread die now, much love.
