Ice race car turbo questions
 

Hey, I've built an ice racer('88 civic dx with mpfi swap, si trans and flywheel, pg7 ecu, 6 point cage...)and raced it for the last 2 seasons, and am going to boost it for this season. I have an hf manifold, a couple of tb0335's(dodge turbos) and access to all of the tools and equipement I need. However I have a couple of questions that I haven't found the answer to. My biggest question is management: the car see's long periods of wot, and quite often banging off the rev limiter to pull through a corner. I'm not interested in chipping my ecu because I don't want to hook up to my computer. I'm getting some 450cc's will a vafc work on my car without vtec? This one? http://saskatoon.kijiji.ca/c-cars-ve...QAdIdZ30541255 I am quite interested in a smc, but I think I read that they don't like wot. I don't quite understand what a vafc does on a turbo car, does it tell the ecu to dump in less fuel with the 450cc's?
Or should I just use a fmu? 12:1? 10:1? I don't want to have fuel system problems after towing 8 hours to go to a race.
Any help or advise you guys have would be great. Thanks.

Hard use like that doesn't seem like a recipe for an afc hack or fmu. Why so hesitant to tune with your computer?

Re: Ice race car turbo questions
 

---- a FMU

Re: Ice race car turbo questions
 

Get with xenocron on here. Hell make you a basemap and send you a ecu.... hack and fmu are junk!!

Re: Ice race car turbo questions
 

Would a chipped ecu need to be tuned? I have no problem putting a chip in, but i don't want to hook my car up to a computer all the time to make adjustments.

Re: Ice race car turbo questions
 

As long as you dont keep putting new mods on, you will only have to tune it once.

Re: Ice race car turbo questions
 

basemaps are junk. if he dosent have a way to tune it he is just as bad with a base map as he is with a vafc

Re: Ice race car turbo questions
 

Since your at WOT most of the time it would be really easy to tune. Build yourself a $100 wideband, a chipped ecu, and borrow a laptop.

Re: Ice race car turbo questions
 

having a consistant tune with a chipped ecu will fetch you more hp for you dollar. even with minor mods there is hidden hp with a up to date tune. also since your ice racing as well, weather will play a big factor when it comes to your tune. slight mods being able to be made in an instant via laptop my seem pointless, but in fact its a big determinate.

Re: Ice race car turbo questions
 

then you will need a ostrich or something along that line to tune while he drives.......


i hate when people say "chipped your ecu its cheaper and easier" when in all reality it aint. is it better for performance yes, but its not the cheapest nor the easiest way

Re: Ice race car turbo questions
 

Ultimately Stock Maps with a built in boost retard and an FMU are probably the safest and easiest route for this guy.

that way he gets a proper ignition retard in boost, no check engine lights for the map sensor, and he can let the FMU do his added fueling...

Re: Ice race car turbo questions
 

word.....i agree

Re: Ice race car turbo questions
 

You really need to talk to Randy aka iceracercrx. You two would be peas in a pod.

Re: Ice race car turbo questions
 

So what I understand is I should run a chip that pulls out timing under boost, and that will recognize boost in the map sensor? Where do I get such a chip? Would it need to be tuned? The car has no VIN so I can't drive it, also I am not willing to pay for dyno time. And run an FMU with stock injectors? What rate FMU? Should I just save these pretty blue injectors for another project?
Thanks guys you've been alot of help so far.

Re: Ice race car turbo questions
 

You would need a chipped ecu and the chip should be tuned specifically for your setup. You can control fuel and timing as well as many other parameters. If you do this you won't need an afc or fmu. Check out the pgmfi.org forum.

Re: Ice race car turbo questions
 

is it even functioning right now ?

Re: Ice race car turbo questions
 

Always has been.

Re: Ice race car turbo questions
 

just run a ob1 chipped ecu with crome as your fuel mangement and burn a chip .very versatile and cheap .

Re: Ice race car turbo questions
 

If you will pay for my plane ticket to and from I would be glad to tune it for free just to ride in that thing. That looks like a lot of fun. I got the tools.
