Fuel Management Problem/Question

[Loewen21]

Ok guys i know this may sound like a stupid question but here it goes.
So i bought my laser in July of 06, and it had everything done to it listed in the profile, i have done nearly nothing besides change a couple sensors and some minor stuff.

It came with an HKS VPC along with the GCC and i am way too scared to touch this stuff for fear of destroying my car, but at the same time me and my friend have come to the conclussion it is not running very well, and getting HORRIBLE gas milage (not even 300k to a tank.)

Just wondering if anyone has experience with this fuel management system or a link to some sort of tech for it. Any help would be greatly appreciaited, thanks guys.

I would start by checking the O2 sensors. When they go bad, gas milage falls!

You should be getting between 350-450k per tank. Do you have a datalogger?

 

[Loewen21]

ya dont have one and i just replaced the 02 sensors so they're all good. Guess it would be a good idea to get a datalogger on it. My friend has one just need to get around to doing it.

Ok well i haven't gotten around to the logger yet but would it be safe to say i could lean it out a little bit, because it must be running horribly rich to get that bad of gas milage.

Don't try to tune without some sort of logging device in place. As you stated you don't want to blow it up, but just remember with your changes make sure to give the ECU some time to re-learn before looing for drastic improvements. There is a wealth of information in this site. So take some time to read about tuning and understand it better so you are not so apprehensive about tuning your Laser.
