I'm wanting to lean out my air/fuel mixture in lower rpm's with my supercharger setup. It's running a bit rich right now. Would a VAFC be a good way to go?
A little background info. Jackson Racing Supercharger on a D16Y8 (stock internals). There is absolutely no one within 8 hours who can dyno tune. And I'm new to any type of tuning. So I'm thinking either of going with a P28 and using a VAFC for some self tuning or either going with a chipped P28 from Phearable.net and using their recommended basemap for a supercharger setup. Would a chipped ecu be able to do a good enough job for my car or should I attempt tuning myself? I'm on a sub $300 budget. The car runs fine and dependable now but I want to get the most out of my setup. __________________

phearable.net is overpriced.
xenocron.com is your better bet. are you running a fmu?? if o, you can actually bleed boost away from your fmu with a ball valve leaning out the mixture by reducing fuel pressure. afc hack is a terrible solution as it advances your timing to unsafe levels. your best bet is a chipped p28 or converted po6 running a good map. like i said, phearable.net is overpriced badly, and i know xenocron personally and his stuff is top notch for way less money. |

Does anyone even read what i post? NO ONE here within 8 hours does hondata, uberdata, crome tuning at all.
And after talking with the people at phearable.net, they don't have a basemap to load for my application. So I guess it's up to me to have someone tune a VAFC since there are a few people here who know how to work those with a wideband. __________________

go with the obd2 to obd1 harness (like 70 bucks) and a chipped p28 running uberdata or chrome (around 130). IF you really want your motor to last id get a wideband (300) and youll always know exactly how your car is running

megasquirt sucks. i played with it, and being someone familiar with tuning, my head was doing circles on my shoulders.
nate, i'd advise against the vafc for 2 reasons... 1.- it has inherit disadvantages. its a piggy back, and your ignition maps are non-adjutable. ignition is where all your power is. 2.- frankly, if people in your area are going around calling themselves tuners and can't operate crome, i wouldn't want them touching my car. you're not an idiot.. you know computers. you can figure out crome. just keep in mind, if you do go with the obd1 conversion, toss the fmu, and run crome, you will need to get some dsm 450's or the likes. your stock injectors will not support it. if it were me, i'd be scouring honda-tech, honda-acura.net and clubsi looking for someone with a jackson on a y8 who has a bin set up. see if they will be willing to email it to you or whatever. i can burn you a chip if you need it... you'll just need to get the computer socketed, the injectors, and the obd1 conversion harness. then, go do a pull on the dyno's wideband and see whats up... if it looks good, golden... if you got some rich or lean spots, let me know where (send me the graphs) and i'll send you out another chip with a slightly modified program to kill the dips and bumps. go again for another set of pulls, and it should be pretty good. after 2 times to the dyno, buying a wideband practically pays for itself though... and that would be something i recommend buying. there are cheap ones with limited displays for around 200... or my choice, the lm-1 for around 300. i realize this is over your budget... but once you're tuned, you can always ebay it and get 80% of your money back on it... |

i don't have a problem with learning crome or uberdata. the problem is there are no available dyno's to use in town. only ones at shops that work on semis, lol... and there's the money issue.
next, the timing is set where it is safe. i'm wanting the car tuned mostly for engine health, not peak power (although desirable). that's why i've considered the vafc since i can at least get the fuel map better. __________________

the stock computer's ignition map is horrible for forced induction. the advance is about 10 degrees too much up top.
you don't need a dyno to get yourself a safe tune. all you really need is a wideband, someone to drive while you tinker, and a nice desolate road |

sounds like the way i'm gonna go. i can get a package with chipped/socketed p28, cable, chip burner, conversion harness, and wideband o2 for $500 shipped. then learn with that, tune other cars for money, and make my money back in a year.

Its cheep and will do what he wants to do . . get proper air/fuel mixtures through his RPM band. All he needs is a wideband o2 to use when tuning the thing. __________________

The guy on this page: http://www.j-k-tuning.com/Infopage.html
He's on H-T and has been awesome to deal with already. I've PM'd him dozens of questions and he's very helpful. __________________

Works with Uberdata. The reason it's cheaper is because you use a program like Uberdata to read the o2 sensor. But I believe there is enough signal leads to wire up a gauge too. __________________
