After comparing the tables the only tables that are different are the neutral A/C on and off tables. The other two decel tables are the same, no differences.

What's really the differences in these tables? Why are the Neutral tables the only ones affected and not the in gear ones? Weird....

Here is a picture of what I am referring to:

 

You sure do make pretty pictures.

 

Well I guess that makes one thing I am good at!

 

Try making the "decel fuel cut delay" tables AND the "Idle steppe Look up table" match those of the 94170015.

 

Also do we have the

- ISCV Demand RPM Adder [rpm > 4500, load > 170, speed > 12 mph]
- ISCV Demand RPM Adder (Moderated by Baro, IATS) (FFFF6EA8) (sub_204B6) [sub_1EFC0]

defined for ROMS 96940011, 94170015 & 96420008, Or did I miss something?

 

I did this and the hang is still present. The RPMs are falling but not as fast as on 94170015 and the AFRs are not pegging lean. They bounce around between 12-16 until 3-3.5k RPMs then they go lean. Anyone know why they go lean at that point and not higher up in the rpm band?

 

And the v7 bugs are coming alive....AHHHHH

 

Nope not considered a bug, since this issue tends to plague all 96530006 ROMS. This thread was started to find a solution that can be incorporated into the V7 ROM.

 

mfr122887 maybe try checking your Base Idle Speed Screw to ensure you haven't wound it out too far. If you log the ISCV steps, it should be around 15 or so at idle when the engine is warmed up properly.

There is also another table you can try zeroing out to eliminate throttle hang.

- ISCV Demand RPM Adder* (sub_1EFC0)

I found that this affected throttle response so I left it standard.
I have been playing with my decel fuel cut tables, as I feel the stock 96530006 values are way too high.

 

I used the Evoscan actuator mode to set the biss screw. At idle, it moves between 14-17 steps so I think the screw is set correctly.

 

is there a number of steps that is good? mine are way up there, around 65.

 

Does anyone know a way to activate Evoscan's SAS Mode to adjust the BISS while being able to still log RPM??? My mirage's tach sucks below 1000 rpm so I have no idea what RPM I'm actually setting the BISS for

 

And this thread was started before V7 came out.

 

Do we have these table for any of those ROMS?? Since the ROMs listed above are ones WITHOUT the throttle hang, I wanna see what those tables are on them and compare to ROMs with the throttle hang.

I think a complete fix may be this.....

Making all the follow tables on 9653 the same as 9417
-all Decel Fuel Cut Delay tables
-the Idle stepper look up table
-ISCV Demand RPM Adder
-ISCV Demand RPM Adder

Also, I think the "Decel Fuel Cut Delay Retard" should stay STOCK. I think retarding timing during throttle lift-off is a good thing.

Oh another side note, I will be switching to 9653 in the next couple days and then Ill be able to work more and test more on finding a fix.

 

This issue is actually on ALL 05+ ROMS. So its not just a 9653 only problem, its an all ROMs 05 and up problem..

Also it defiantly has nothing to do with V7.
