just got an apexi vafc off the streets.... owner told me not to change the settings cause his settings made his civic(swap gsr w/ basic bolt ons) pull hard on 2nd and 3rd...but i was wondering if his settings would have a good or bad effect on my 99 lude considering that his settings was for a civic/ gsr. would it even matter?... i havent installed it yet...thought i get more info oh and plus i heard that the lude's 0bd2 ecu will throw a check engine light if vafc was installed...is that true?????
any info would help

 

what works for someone else's engine will not necessarily work for yours. Esp across platforms like that. the best thing to do is get it dyno tuned. it costs money, but you have to pay to play. Without a wideband O2 sensor, whatever fuel/VTEC adjustments you make on a VAFC will be inconsistent and potentially dangerous to your engine. some people road tune, but keep in mind that these are very experienced tuners who know what they are doing and have lots of experience with a particular engine, Fuel Management setup, and set of mods. It's always better to dyno tune anyway, it's just that it costs more.

about the CEL, if it's installed right, there isn't an issue with an OBD2 ECU.

 

EDIT: READ What monkey said... He beat me to it...

I personally would not run my car with someone elses settings, if you do install it get it tuned by someone who knows what they are doing... every car is different and you don't want to mess around with the wrong settings...

On the check engine issue, I've never heard of it, mine does not throw any codes although I did install a workaround switch...

 

thanks guys... one other thing i forgot to mention earlier is if im gonna have to cut any of my ecu wires to install the vafc...or is their some type of wire harness i can buy to avoid cutting my ecu wires???

 

oh SIR_VTEC what type of body kit is that on your lude ...simple and aggressive....NICE!

 

it looks like wings west rs sides and rear....not sure bout the front...could be greddy or also wings west rs

 

yeah it's the Wings West RS kit...

 

i didnt wanna start a new thread so i jus figure i put it here.....i have a v2 intake, aem pulleys, nology hotwires, and im putting in a rage header(2.5" collector) with a hi flow cat and magnaflow muffler with 2.5" exhaust piping....obviously a vafcII wud be a great idea and im planning on getting one ...i jus hear people talkin bout converting to obdI...is that necessary for wat im gonna do?? i really wanna avoid screwing with the ecu like that

 

you only have to convert to obd1 if you're using hondata or a similiar ems not with a vafc.

to jonsuper7, what mods do you have that make you feel you need a vafc?
