SD2 tuning

[daveismissing]

Can tuner pro still edit the tables in a SD chip like it can in TT's ?

From the research that I've done, yes. But I would still talk with Eric to see if there are any idiosyncrasies with it.

Spoke with Eric last night for about an hour.  Man that guy is sharp!  He confirmed a few things for me and blew some other thoughts out of the water. That's why I called. My thought process of tuning was on track but was pulling to one side of the road. He set me straight. I don't have enough words to express my appreciation for him. 


I had no idea that there were some internal tables not available for viewing/[size=78%]tweaking, and that's where my confusion started. I was thinking that I set the fuel parameters to 128 and then tweak the VE tables.  He suggested getting the AF correction as close as possible with the fuel parameters and then tweak the VE cells. The VE table doesn't auto adjust when changing a fuel parameter cell. The fuel parameter cells haveinternal fuel trim tables that are not available for viewing. [/size]


Again the learning curve...

Eric is brilliant, but he is also a really nice guy as you say. Glad he got you back to the center of the tracks

With all that was going on yesterday, I managed to get out on my back road test site and make a high gear pull.  With Eric's input in the tune, I believe I'm headed in the right direction.  This was still a test with low boost and a 10.8 target AFR. I'm going to keep the same boost setting and adjust the AFR to see where I can tweak from here.  As I've mentioned before, I'd like to have a street tune at this boost level and then a "turn up the wick tune" for the track.  Baby steps...

Looked at that log Jason.......lo oks nice and clean to me...... O2's are nice n safe. Glad you got it running nice!

Thanks Guss!  It looked pretty safe to me as well. Gonna try another high gear pass with the AFR set at 11.0 and go from there. Eric says 11.0 -11.5. Think I'll go .1 at a time after I get the 11.0 dialed in.

Only so much memory in the chip

More to the point there is only so much memory that the CPU can access

[good2win22]

Was able to make another high gear test pass this afternoon with the AFR set at 11.0.  Please have a look and tell me what you think.

The break up happening around 5000 rpm is what was happening before but that was before talking with Eric and the chip was pulling over 10% fuel. Seems to me that the combo liked 10.8 AFR better. This log shows the wideband really jumping around and the fuel correction really hunting as well.  Something else is the lean spike as I'm getting into the throttle.  Is there something that I'm not seeing?

[good2win22]

Got a call from a little birdie last night and he suggested I change the TR6 back to stock ignition.  That's what I did.  Same settings on the SD2 set for 11.0 AFR.  Almost the exact same ambient conditions as yesterday's test pass with a little more wind.  KR wasn't as high this time but still sustained around 5200 rpm.  Perhaps 10.8 is all this thing can handle

Are you using original coil and module or after market or ac Delco pieces for the "stock" setup?

Rich the stock ignition is just that. Original equipment stuff minus the plug wires

[TexasT]

Man you have a stash of stuff. I have been thinking of going to a new module and coil on mine as it seems to stumble at wot. Though I ran it real low on fuel a week or two ago and ended up putting in 14.5gallons. After that fill up I was able to get o2 in the low 700s pretty cool as it was dropping of to the 050 range before that .

Point is I guess I wanted to know if there is a good after market module to get or if I should think on some thing used.

I have a Type II Ignition system for sale, But i can't post pics.Let me know your e-mail and i'll send to yea.

I've picked up a few things over the last few years. Believe it or not Dave Husek has a stash of OEM parts that he sells off ever so often. That's were I got my NOS cam sensor a few months back.

I'm not certian that I have an ignition problem just yet.  Thanks for thinking of me though and I'll definitely keep you in mind if it comes to that
