SD2 tuning

[Scoobum]

Are they gold or tin? ECM and PL?

Tin

Eric emailed me back. Man is he an awesome dude!  As usual he set me straight.


Pulling fuel from blocks 5-8, pulls fuel from specific vacuum areas on the fuel tables thus increasing or decreasing the fuel correction. Pulling fuel from the VE table will increase or decrease the fuel correction at a specific point at rpm and KPA.  All that is irrelevant if you have block 4 set to a hit a specific AFR, which I did.


His recommendation was to set block 4 to 97, which is closed loop but uses AFR table that can be adjusted to your settings, and then go into the AFR table to adjust specific cells for the launch.


Also, he mentioned that he thought the converter was too tight.


It will be at Jake's on Friday to get it loosened up.

What do you think that converter is stalling and flashing to?
Is it a Nissan 245mm core?

Block 4 allows you to set a predetermined AFR. Is that from a certain RPM? Or from a certain boost level? Or certain gears? Fill me in.

In regard to launch cells...what do they cover. 1st gear?

It pushed through the lites at 3450. I'm gonna guess he loosens it 250 RPM.

[Steve Wood]

I would say 600 is the number

It is a 245mm core.  As for stall... Not enough

Block 4 is fueling when above about 13psi of boost


Brad you kind of have to forget about the blocks as low gear - high gear.  Everything is based off rpm and a vacuum/boost level. The fueling blocks are for a quick adjustment to fuel tables to adjust the AFR correction at certian vacuum/boost levels.  To fine tune the AFR, you have to understand the relationship when telling the block to go closed loop and use the AFR table verses telling the block to try to maintain a specific AFR.


This is not tuning like I learned with narrow band and Eric's 5.7 chip. It's way more in depth

[Scoobum]

Thanks Jason. I haven't got the patience or time for that. Far easier for me to make a practice pass with the car and come in and look at the fueling at the shift points and add or subtract as needed. I'm ready to raise hell on the 2nd pass.

  I have yet to get the SM-G to work wirelessly. Hate to bother Bob about it when the cable works. He's a busy dude.  The glitch with the log is just the latest in the line of frustrations.

I was reading up.on the  logger thing . Are you using the dropbox and the correct apx file in the file on your computer or tablet? That may have been for the aldlandroid app for the wireless tablet lots of info. Hard to keep it all straight. I'm fighting an uphill battle with window 10. Son assembled a new box for wife with ssd drive. It is fast but not without pains for this operator.

I have no idea Rich. Had to do some turning on and off of some settings to get it to work with Windows 10 and the cable. Tried the wireless a few times to no avail

I believe that is to set up a scanmaster G (round) using androids

PL pisses me off!! You hit the record after burnout save file at end of the 1320.......... then go to review and you have half the run. Too inconsistent IMO. I've made my best runs with that thing unhooked and sitting in my P/U. Set the fuel and timing in Erics chip and watch the SM and let er rip!

Set up to trigger on the throttle.  I have mine set to start recording at 3.5V and 10Sec min.  That usually gets all of my runs including the burnout.
