closer... closer... I wonder how your 6speed will work out? You have yet to find all the bugs...

I've actually moved the car up the street in an attempt to test drive it in the past so other than fine tuning the shift linkage for a better feel there shouldn't be a bug with that part of it although one axle isn't exactly the quality it needs to be. You keep the bug ideas for someone else, I've already met my quota.Originally Posted by IsaacHayes

Cool. IIRC didn't you press fit the axles together with a tube or something? That's what I'm wondering if it will hold when the real power hits the road. BTW did you use the G6 shifter (handle) assembly, or some how modify the 5spd one?
Not sure what the bug in tunerpro is. have you tried setting the RPM limit in TP really high, and then checking in tunercat? Maybe you gotta set it 2000 higher than what it says for it to be where you want? I know tunerpro has a bug in recording data logs on my car. It will display fine but when it records it is corrupt and won't play back, and if you make a .csv from it several tables are emtpy.... ScannerPro works fine but doesn't export .csv yet...

Someone else on the Fiero forum tried press fit axles and no it didn't work well. The Fiero four speed shifter is the best option with a few modifications for the shifter.Cool.

The bug is in TunerproRT, if you max out the limiter fuel cut I believe, it will show just over 4K in Tunercat and will limit the rpm eventhough the value shows over 6k in Tunerpro. If you enter more than 6k in Tunercat it will register as just over 4k in TunerproRT but rpm will not be limited before 6k so the problem is in TunerproRT, thank goodness I happened to have Tunercat.
I've driven the car but it needs some more tuning, I'll have to connect the OE 3900 O2 sensorto power to get it to work properly it seems, so far the car has not gone into closed loop as far as I have datalogged so either it needs the heating option or it just will not work with the 730ecm. Since there are 4 wires I'll need to make sure I have connected to the proper wire.
I haven't seen boost just yet and have a fitting or two open allowing pressure to leak that must be closed.
I'm gonna guess here and say the 3900 O2 will not be compatible. Superdave was running the LX9 3500 O2 for a while but it never acted right, he went to the older style 3400/3100 heated ones and it works much better. They must have changed something in them.
Did you try to contact Mark about TunerPro? Or is it maybe a bug in the bin mask file thingy?
EDIT: Are you running the latest version?
v4.14.0381 (3/16/08)TunerPro Free & TunerPro RT
- Fixed Internet update server connection issue
- Fixed issue with Function item editor, where axis limits weren't being stored correctly

Actually it appears the sensor does work. I didn't have the ground wire connected and when I supplied it with power the ecm went into closed loop and held it for about 95% of the data log which was about 3 minutes long. A code 45 set for rich condition and the integrator bottomed out several times at 76. The BLM didn't move much but then that may have had something to do with the rpm level which was mostly above 2K.
I checked Tunerpro updates today and did not see an 08 correction. I do have 4.14 something.
I'm having a bit of trouble with the alternator. I installed a little 5v regulator today and it appeared the voltage went up a bit more over 13v but later on it started registering in the 12 v range on the datalog. I'm not sure if I damaged the alternator with the 12v feed or if the regulator is not carrying enough amperage which I doubt. I'll have to take it and have the system checked.
Mean while, I rigged the oil filter relocation adaptor by putting a layer of aluminum inside the threaded hole to tighten it on the nipple since GM decided to throw a curve and put an odd thread pattern on it that doesn't fit the available adaptors properly. As you can see in the picture it blue it off while revving around 6k and it's a blessing that it happened in the drive way and that the car didn't go up in flames because the oil doused one of the glasspacks. I'll check into have an extra adaptor tapped with the proper threads in the morning. That incident suggests my oil pressure gauge is way off and that the 80 psi I saw at one point is actually correct and the low 40 and below reading is the result of a bad sensor that's fluctuating as it has done for a while now, at least I hope.
STILL COULD USE SOME INPUT ON THE ALTERNATOR ISSUE.

That hot link was an accident, the link was in my clip board where I thought I was linking to the video.

I love the idle. What cam specs did you choose, and what RPM is idle?
Can't wait to see it in action!
EDIT: Watched the video again, and just before the baby blip, it looks like 550rpm?

Yeah the idle drops from time to time and I believe in the video during the tale pipe shot it might have been as low as 400, the dual mass flywheel probably has a lot to do with that and I believe the Harley Davidson engines have a heavy flywheel that helps them keep chopping at very low idle. My idle is actually set at around 950 but tuning and possibly the IAC passage has an effect on it. The throttlebody adaptor plate from the store had to be modified because it has no passage for incoming IAC air so it's possible I may need to make the passage larger though I doubt it.
I attached a datalog sample from Tunerpro in the tuning thread. I will have to hot link my converter directly to the battery since the circuitry built into it shuts it down if it doesn't see the battery voltage it wants. My laptop battery is shot and the computer will not run more than about a minute without auxillary power so hopefully the shift cable will arrive by 1pm and I can install it and test drive the car to get some on road data for tuning after I bypass the cigarette lighter and plug into the battery.
I did a moderate test drive today since the water injection kit is not installed I didn't want to push it to hard along with the need for more tuning. At the moment it's more of a top end ride but hopefully tunning and smaller turbine housings will restore some bottom end grunt. If not, at some point I'll install the stock camshaft and incorporate the VVT in a basic on off function.
