Fuel and Tune Questions?? turbo build almost complete

[RoCKstArTEgGy]

Okay well i have all the turbo parts including the fuel system upgrades and all. I have a few questions before it all goes n the car. A few odds and ends to fiure out. First ff... do you need a missing link AND a map sensor or is it just one?? and if just one than wat size map sensor for 10 pounds of boost?? Im using the chipped ECU i bought from phearabe.net for running crome. Where do i buy the cable to connect my ecu to my laptop?? Has anyone tunned with crome on a bosted integra that can lend me so tips on the prcedure??

Well they make different bar map sensor, how flexible you want your tuning to be is up to you. Stock is two bar, they make 3 and 4 bar also. You will not need a missing link. As for chrome, it tunes the same as anything else. Adjust your a/f every 500 and make sure your stoichoimetric. From there you can lean or richen to get more power as long as it's stable. Also you'll need to be adjusting your ignition timing.

so should i get a map sensor?? and to advance timing do i need to use a timing gun and do it that ay or does crome have a way to do it>?

I'm not familiar with chrome but if you're boosting an internally stock engine then you aren't going to want to advance the timing. It will need to be retarded some

 

[RoCKstArTEgGy]

okay so no map sensor. and retard timing a bit..but how to i connect the ecu to my laptop???

 

[Aussie]

Your stock map sensor will be fine. What motor are you running?

b18 nonvtec

any one else have anything to add before i finish buying??

not sure if i got this correct but it seems like you are trying to tune your car yourself? I would not recommend this untless you really know what your doing and have a dyno. Street tuning is not the way to go anymore. And the concept of tuning a car for boost sounds easy but it requires experience. I would find a tuner instead. Just my two cents

 

[RoCKstArTEgGy]

well i just got off the phone with a local street tuner that can do it for $225. He has a very good reputation and for that price i would rather have him do it.

Got a bit of a problem. My injectors arrived today and i thought they were 450cc but they are actually 1000cc injetors. If i cant return them and i have to keep them will they work or do I need to sell them???

 

[Aussie]

1000cc will work but you will have to tone them down a bit. You won't have the the delivery like you would with a smaller injector because they will spray less often.

 

[RoCKstArTEgGy]

so how will that affect throttle responce and power?? do i tone them down when it gets tuneed or do i have to do it some other way??

 

[Aussie]

When they squirt they will squirt the same. All you can control is the length of the squirt and how many times it pulses. So your going to slow down the injector pulse and duration. It's not as good because your not getting as consistent fuel delivery as you would with a smaller injector. This is why I always tell people to get an injector just big enough to handle what you need.

 

[RoCKstArTEgGy]

well i got an amazing deal of them because the person had no idea wht they were so it was kind of a risk. They are RC 1000cc injectors Brand new. Ill try to sell them or trade them but if not theyll just have to do. As long as the tuner can fix the problem
