On boost it seems to run great. Its just the low throttle is harsh which like everyone is saying is common with large injectors.

The car also has a dynatec ignition box

Re: Potential Buy 1997 GSX
 

Only for traction reasons/launching I keep boost lower in 1st gear. I don't have traction problems in 2nd or 3rd.

Re: Potential Buy 1997 GSX
 

One of these days ill have to get the nlts hooked up and set up as the previous owner didnt want due to the 47lb rims that are still on the car

Re: Potential Buy 1997 GSX
 

You on e85 or 93? That would make a difference as well. 12.1 would be really lean on pump gas IMO. I thought you wanted to keep it at like low 11's on pump?

Re: Potential Buy 1997 GSX
 

I hope 47 is a typo or something, that's unreal.

Re: Potential Buy 1997 GSX
 

Nope not a typo he said he weighed one of his rims with tirenamdnit was 47lbs.

They have a good two-three in deep lip on them. They look good imo minus some curb rash.

Originally I was like they have to go. But I might keep them for daily use then get a trackset.

You can see in the picture I posted earlier. That the front tire has brake dust on it and it almost a looks gunmetal with a polished lip. And I really like that combo. There is a new powder coating place in town. Maybe tax season next year might put that on a list of possibilites

Re: Potential Buy 1997 GSX
 

This is on bp 93oct

Re: Potential Buy 1997 GSX
 

47 actually isn't bad WITH tire. If it was 47 lbs wheel by itself it would be a different story! I think a stock Evo 8 wheel is about 20 lbs + a 25 lb tire would = 45 lbs.

What size are they?

Re: Potential Buy 1997 GSX
 

they are 18x8 the offset is a bit much (not use what it is though) If i hit a bump hard enough they'll rub in the back.

There is a guy in town that does fender rolling I may do it at some point as its only like $15/per fender. But that is a long way off on my list of things to do.

Re: Potential Buy 1997 GSX
 

laptop just showed up so i'll have logs tonight on my way home from work.

Anything specific to log?

Re: Potential Buy 1997 GSX
 

RPM, timing, knock, and AFR and boost if those sensors are hooked up to the ECU. Those are a good place to start. Is this on speed density or MAF? If it's on MAF, then logging airflow Hz isn't a bad idea too.

Re: Potential Buy 1997 GSX
 

It'd on sd.

Re: Potential Buy 1997 GSX
 

Jet - i know you mentioned the wideband sensor could be going out. Which one os the replacement ?

Map has one for 85 and then a kit for like 95. But the pictures of the sensors aren't the same and the non kit one I dont believe has a part number for it. And I didnt see anything but Bosch sensor with the full gauge/harness aem wideband.

I checked under the hood before work and the sensor on there has the black plug for the harness like the 95 dollar kit

Re: Potential Buy 1997 GSX
 

I only mention the sensor because if they go out some what often then it might be best to have a spare

Re: Potential Buy 1997 GSX
 

You have to get an AEM specific sensor for the UEGO.
Edit: after looking at their site, it's not clear whether the UEGO replacement sensor for $84 comes with the harness or not. You certainly don't need the SS bung that comes with the $97 one. I would call and ask if the cheaper one comes with the pigtail and black harness that you need. IIRC, each one is pre-calibrated so they should come with the harness.

Re: Potential Buy 1997 GSX
 

I looked at your logs on the link forum and noticed you wern't logging your map ait or wideband I'd add all of those. you will have to setup the pin assignments in the ECU inputs tab under ECU config.

I also noticed in the logs your ECU is pulling a lot of fuel. like -20 combined fuel trim. Your global fuel is set to 60? I put 2200cc injectors in the calculator and it came up with -66 for global. you could try that and it should bring your fuel trims closer to 0. just remember a change in global will affect you air fuel ratio under boost.

Re: Potential Buy 1997 GSX
 

Carl ill do a wot pull on my way home with the current settings and then ill load those settings.

Re: Potential Buy 1997 GSX
 

Global set to 60 w/ 2200cc injectors? Either shit has changed drastically since I've used Link, or the dude got it tuned at the Waffle House.

Re: Potential Buy 1997 GSX
 

Ya I was wondering the same thing to be honest. I noticed that then I asked him to send me the tune for e85 he had and the settings were the same.

When you do the calculator that comes out to like 1150 or something and that's what he had before the 2200cc. I was wondering if they forgot to change the settings or he forgot to tell them.

Or the injectors on the car aren't 2200. I never checked.

I was going to adjust the global but I couldn't find the dead times for them so I never changed them

ok got some logs tonight before the laptop died (left it on while at work)

anyrate some wierd stuff happened also unfortunetly no logs when it did.

first log i missed 4th gear causing knock. wide band reading 10.5-10.8

2nd log i started at like 2500rpms and it knocked enough to get my cel to trigger. (had never done a pull from that low rpm yet. wideband was reading 10.8

3rd pull cant remember if anything special happened.

anyrate so wierd stuff. after these pulls i have like 15min of my trip left to get home and you can't speed due to cops, deer, etc. so doing the speedlimit.

I get into town and i have to come to a stop sign and make a right. well when i went into neutral the car was idle surging and the wideband was swinging all over the place full lean full rich, I tapped the gas and settled down. went to get going and it started again and hte car started bucking really bad, quickly popped it inot nuetral (doing like 5mph now)... if it matters car had 1/8th of a tank of gas left....

anyrate put it into gear and tried again stuttered like normal when into 2nd gear and statted stuttering real bad almost like a blown i/c piping. for a spilt second. wide band once again swinging like crazy.

tapped the gas and the wideband settled down and car went on like normal. no idle surge, wideband was runnign normal (from that stopsign to my house is like 1/4mile)

pulled into the drive way all is well nothing weird, shut the car off no sounds of bubbling, etc just quite as can be. Oil's fine, coolant overflow is normal.

couldnt find anything wrong.
