Hey guys,
Does anyone know how I can decommission my 99 gsx from emissions did a six bolt swap have check engine light and not much money but I have a feeling I'm gonna be getting that yellow slip
Soon ### help
 
No. Your car is a 99 and will always have to pass a plug in test. What is the light on for.


EDIT: I'm not familiar with ecu flash. Maybe some one who is can chime in. It might be possible using ecu flash to set the readyness monitor while not allowing the ECM to run the system test. That would be the only way assuming your talking about the random misfire code.
 
As the Car sits right now it still has a idle surge and has 14 codes in it pretty sure that some are from one thing failing and then throwing a code for others.
I'd move if I could a friend of mine was telling me that his buddy some how got his car to never have to do emissions again
he had to take a picture of the racing seats steering wheel and seat belts and they changed the "title" of his car to a street legal show car or race car something or other been trying to figure out how he did it haven't been able to drive the dsm in 4the months got pulled over for expired plates and loud exhaust and I can't renew the plates til I get threw emissions
 
I don't know about where you live, but here if you drive your car under 5,000 miles a year, you can get a exempt sticker.
 
Did you swap the 6 bolt in it complete? If you did, thats probably why. When I did a six bolt swap I used the cams and everything from the 7 bolt on the six bolt including the intake and exhaust manifolds, even the cooling system distribution pipe and thermostat housing......the only thing that stayed 6 bolt out side of the long block was the flywheel....other than that everything else was 7 bolt. I didn't have one code.......If your trying to use the entire 6 bolt then you'll have codes for a ton of stuff the computer wants to see that isn't there........and for the record, you don't have to remove the emissions equipment to make a car more powerful.....I think a lot of people do it cause of the cleaner looking engine bay and they're to lazy to re-locate some of the emissions equipment to get the same effects of an engine without all that on it-

I have a 299 scanners don't recall the codes of the top of my head
I live in Illinois
I just put the 6pipe bolt motor and trans in did the wiring ti put the cam and crank together stock block wit balance shaft eliminator kit ARP head studs, stock cam,stock crank, stock pistons and rods. Took it to Devo 2uning because it had a bad idle surge and needed a tune and was supposed to be fixed to pass emissions 1500 bucks worth of work and still has a small idle surge and they street tuned the car saying that putting it on the dyno would make it run shitty on the street witch doesn't make sense to me but ok
got the car from my cousin and I don't know if it was him or the owner before him but I'm pretty sure some of the emissions sensors are not in the car.
I talked to a place called Boosting performance about fixing the car and they'd do it but just recently my wife gave birth to our kid and don't have much money to put into the car right now

Dyno tuning doesn't make your car run shitty on the street......The drivability tune and part throttle maps won't be perfect but it doesn't make your car run like shit. If the tuner was up on it, he would wot tune you on the dyno and get part throttle maps close then street tune you to clean up the spots on the map that were rough and wouldn't be obvious on the dyno because the dyno can't load the engine the same way the car will be loaded when it's on the road....That sounds like a red flag to me brotha.

All that aside though if you used everything complete from the 6 bolt engine and then rewired it to make it work you did it the hard way IMHO......just transferring the 7 bolt parts to the 6 bolt bare long block didn't take all that much more time and the sensors that you need for everything to work properly is all there. Right now you ecu doen't know that the engine is older than the car is and it simply sees that a bunch of things aren't there. Your tuner could've tuned it from now till the next selestial alignment of the earth moon and sun, if it's not running on an HKS F-Con V-Pro or an AEM it's not gonna run right. Even a DSM link probably wouldn't have made it run right.


Sense you already re-wired everything it may be pointless to make everything work with the stock computer your best bet may be going with a different ecu that ignores anything that doesn't allow your car to run (I.E. evap emission equipment) and a host of other solenoids and sensors that the 2G cars use, that the 1G cars didn't....... (A.E.M. is one of these ecu's) otherwise you may be un doing alot of what you already have done and transferring alot of the sensors from the 7 bolt back on to your 6 bolt so that the car is happy.....

Don't be surprised if you must have the car re-tuned by the way....

Yea that place was garbage pretty much lost 1500 bucks but yea before I took it up there I was looking in to getting a new ecu even tried a ecu that I got from a buddy but wasn't plugged how he said it was but i shoulda done it in the first place especially since a new ecu tuns about 1100 bucks and if that didn't work I'd be doing a lot of shopping around the old motor was junk had a fist sized hole in the block and when it blew the rod it shot up and smacked the top of the motor guess ill just have to start saving get the new ecu and go to boosting performance and hope it works

And I also don't see were they could of safely street tuned the car without crashing in to someone

Thats just one more issue that you face trying to completely set up a car on the street- Unless you have a dedicated runway there's almost no way to stay in the throttle long enough or safely enough,to get a finite tune on the car.....there's just too many things around you that can go wrong.....
