Potential Buy 1997 GSX - Page 7

also carl - i couldnt find inputs for the ait, and the wideband. (wideband is in the front 02 location)

to check which pins these go to... im assuming i'll have to check wire colors and then follow it to the ecu?

or how do you tell which pins they are using like you mentioned?

turbotalon1g · 06-05-2014

Seriously?

Yes make sure the guy physically it to the ecu, then change the settings in the ecu.

I get being on a budget, but it might be worth paying for a tune once to learn these things or taking more than 5 mins between every post about dsmlink.

They have provided a bunch of videos showing how to do everything, start there.

Your WB02 seems to be working correctly, I wouldn't replace the sensor at this point.

Yes I tend to ask questions while i'm thinking about them, vs before I get home to do research. In this case I haven't started researching wide band install yet. But once I actaully get started on this today I will.

I assumed being set up by shane phillips all of this would have been done correctly. (the pump gas tune however was not done by him, and starting to lean towards I doubt he even got it done as nothing was changed on the timing curves or much else that I can tell)

Pinout info (should help with finding that WB and other items wired to the ECU):

so if it was done correctly and im reading it right.

Wide band should go to pin 76 - color white
Ait - should go to pin 72 - color is RL

SlowWhite · 06-05-2014

ok just checked the ecu. Wide band is going to pin 76.

however not sure about the ait sensor. (because it says ait is pin 72, but baro is pin 85)

I texted "agent ezzard" asking him. he said the car is set up using the plug and play harness. The gm map sensor is dipicted as baro on the logs.

SlowWhite · 06-05-2014

i also asked about the global settings and injectors.

he said the injectors are bosch 2000 (i had them wrong he did list them as 2000, not 2200)

also they are high z and the resistor pack has been removed from the car and that the globals can be all over the place those settings just were what worked for him.

SlowWhite · 06-05-2014

also if anyone wants to compare - i posted the 426awhp e85/30psi settings on the ecmlink forums (same link i posted above)

I read most of the wiki earlier but the video's were much more help (always been a bad test taker.. i can do thing much better hands on then i can through reading)

And as much as I am dissapointed that it doesnt look like he had the car tuned for 93oct prior to pick up. I'm actaully now in the mindset of looking forward to setting up the car myself. Will give me a much better understanding and knowledge about cars that I always just paid people to do in the past and never took the time to learn.

So bare with me on the questions and thank you all for the support and help.

SlowWhite · 06-05-2014

Looks like I have the weekend off. Thinking of taking a trip to cmp racetrack to see if they sell E85 or if the gas station at the entrance sells it. (Its just a right turn out of my neighborhood and 16miles away) I didn't see it listed on there website but. The drive has plenty of straights with nothing around. Should make for a good trip to get some logs.

turbotalon1g · 06-06-2014

That's awesome you have a track that close.

On dsmlink change your Sig to show all your significant tuning mods, it will help people know went your tune is the way it is and help speed the process of getting help

SlowWhite · 06-06-2014

anyone know the dead time for these injectors? bosch 2000cc using base fuel pressure

SlowWhite · 06-06-2014

I started from scratch on set up did the injectors and idle so far will do cruise logs on the way into work, and loaded logs onto ecmlink (same thread as above)

let me know if i've missed something or need to adjust something

SlowWhite · 06-06-2014

Well drove into work. And noticed a few things.

The car doesn't nearly stutter as much, as often.

Also I noticed the wideband isnt reading the same as what's on the gauge.
If the link shows 12.1 the gauge is around 13.4 now. Or somewhere close to that.
The gauge also now reads on the opposite end of the spectrum then what it was doing.

Before it would go to 10.5 when I'd get on boost now its at 15-17.

I only tried actually getting on it at over 50% throttle once to pass a farm tractor doing 30 in a 55mph.

And it started to buck real bad so I backed off and passed slowly.

Ill post logs tonight when I get off or ifn I can figure out how to hook ot up so it used my phone for internet

SlowWhite · 06-06-2014

Again I haven't got the chance to set up the "cruise" settings like they say to do in the tutorial or review the logs.

SlowWhite · 06-06-2014

If I switch the wideband from aem to the linear wideband like the previous owner had it set up should that match up what link is saying with what the gauge is saying? Or is that the wrong thing to do? (Im not in my car to test this out on my own just remember someone saying you ise linear if there is a difference in the gauge vs link someplace)

Get it professionally dyno tuned before it blows up.

This. 15-17 AFR while in boost is not good.
At least find someone who knows what they are doing with link and speed density tuning, and who is willing to physically be there with you helping. Otherwise there is a good chance this won't end well, it sounds like you are in way over your head after being out of DSMs for 10 years.

dsmghost · 06-06-2014

Yeah stop driving it like that it needs to be dialed in. It may not just be the tune either.

And use linearwb if the logged value is different from what the gauge displays. You enter user defined voltages to get them to match. But you need to have that tune dialed in better before you can setup linearwb correctly since you have to force a rich and lean condition to get the voltage values your going to need.
