Any way I have A 1988 CRX HF with an 1999 b20z jg stage 3 head full built with all motor cams and a jackson charger and I am Getting about 6 miles per gallon on the hyway does any one know what I can do to get better gas milage? It is only throwing one code it is 13 that is the baro sensor I replaced it and still have the code and I reset the computer.
Please no smart *** remarks.
This is pretty serious

 

what are you running for a fmu? This might be part of your problem...also what ecu are you running?

Josh

 

jackson fmu with b&m regulator and I am running a gude ecu programed for the setup.

 

know anyone with a wideband?

 

yeah got one on my h22a hatch, its a uego

 

all motor cams dont like boost..

 

But its a supercharger?

 

it runs like a scaulded dog but this gas milage sucks, it sounds like a v-8 supercharged with the lope and the whine, I just put it all together yesterday, so I havent had time to go to the dyno yet, but I have allready filled the tank up 3 times in the past 24 hrs.

 

ok, but you said you have stage 3 cams for all motor that is most likely whats eating all the gas... untuned would not use that much gas...

 

so even if it is tuned what 7mpg?

 

what i am trying to say is that all motor cams are not for boost.....

 

agreed but how can I fix my problem?

 

put stock cams in or go all motor....

 

most people tune only for full throttle....you need to get some one to do some street tuning for partial throttle....this might solve some of your gas mileage problem....

Josh

 

Change cams

 

so you thinking that I cant do this set-up?

Not if you want 30mpg.

 

also....are you just throwing a code...or is the check engine light on?

 

check engine light on but only that code????

I would get the code fixed before I started making an switches. Then, I would have the car tuned well at partial throttle conditions...and see where the mpg's are at. You need to realize you're definitely not running anywhere near stock, so don't expect to see stock numbers.

 

Buy a beater and keep your rocket @ the track. Thats about the same gas mileage as the track EK that had a supercharged k20 that was in Honda Tuning I think, it was yellow had a homemade wing. - Darrell

 

This is my beater, my race car is a turbocharged h22a hatch.

 

your beater has a swap and blower

get a stock dx as a beater
your own fault *not to insult a motor build up* that it gets that kinda milage.

can't make a race car get milage like a stock car

lol.

Ok, fix the code and tune it. Your not gonna be getting 30mpg if you don't tune the car and even with it tuned your not gonna get 30mpg but your gonna get more then 7mpg.

Don't take of anything until you get it tuned. Taking the cams out will not instantly boost your gas mileage.

Tune the thing.

 

all motor cams not good for boost,get cel fixed,tune it for drivability and mileage at partial throttle and tune for race at full throttle.....gonna get better gas mileage if you do these things,maybe 20 at the most??
