Tired of looking for the right answer.. IX rpms hang up when shifting
So... On page 36 in Merlin's EcuFlash Evo tuning guide he explains how the "decel fuel cut delay" table/s work. He goes on to say that it is an effective means of addressing "throttle hang". Throttle hang can be caused by several things but... this table controls the time the injectors continue to operate after the pedal is lifted. Target the 60-70 load cells.

Yes into the v7 XML file. I believe mfred found the tables, I'm on my phone, so I would post a link to the defined tables but am limited. Do a search for these tables in the ecuflash section and his thread should be among the top. Forgive me if I didn't give credit to the correct finder of the tables but I remember Mfred name vividly.
Add them then edit them. Be wary of what your warm idle is set at to insure stalling is not present after hard or quick decel. The table posted completly eliminated the throttle hang.

Then why would it completely eliminate the issues? There are others who have found these tables to work completly without effecting cold start!
Messing with the ISCstepper table can do it as well but also effecting cold start, and on E85 thats a pain! The RPM adder tables work effectivly on throttle hang issues.

The RPM adders are only a small piece of the puzzle to completely eliminate the throttle hang.
Yes, do NOT mess with the ISCsteeper table. That was the first fix I and others found in 06-07 and is not the correct way to eliminate throttle hang.

EDIT: Also the thread you posted has the definition for the Decel fuel tables in the first post, as they are the correct fix. Did you not even read the thread you posted a link too?

The correct solution is in post #12 of this thread.

These were not changed and the throttle hang was gone completely... I know the decel tables help a lot too but not the cure all.Even you said this...

Either way not trying to steel or ruin a business or a reason to get tuned. Just trying to help the new self tuners who are trying to learn as well. Im 100% positive that using the table I posted eliminate the throttle hang issue.

Im not worried about business. I dont do this for money. I do it for passion.
And Im sorry to say again, the RPM adders are not the 100% way to eliminate it. This has been tested many times be me and many other. The fuel decel tables are more important.
Also, did you read the first post in the thread you linked? Didnt you see me being quoted in the first post??

EDIT: Also the thread you posted has the definition for the Decel fuel tables in the first post, as they are the correct fix. Did you not even read the thread you posted a link too?

Oh I did and have been playing with them for a long time on Evo8's that commonly have this issue, but IX's its not as common. Theres more than one way shear a sheep, but you can only skin it once.
If it completely stops throttle hang by changing two tables why change the others? What is the negitive side to only changing these tables?

The issue is only an 05+ issue. It was added by Mitsubishi for emission reasons. 03-04 EVO do NOT have the throttle hang.
Please do more reading.
No NOT post #2. Post #12 in this thread, as I said. Quoted below.
And the post of mine you quoted said just want I said above. The RPM adder are a PART of completely eliminating the throttle hang, but the decel fuel tables are the key.

I understand what you said. I dont think it needs to be that complicated and change a million tables. RPM ADDERS have worked on every evo i have tuned.
The only reason I mention business is your sig.

The RPM adders have 100% of the time elliminated it for me on many evo's. Maybe climate or other hex changes are effecting yours and not mine or vice versa.
Evan Smith
2005 Evo's are also known as Evo 8's (look it up, read more

)I have seen T-H issues more on 2005 evo's than 2006 in fact with over 30 tuned ix's I have only seen the one above with it.
Please chill a little bit and not read so deap into everything,

Post 12 was a quote of post 2 with a question???

The RPM adder tables DO NOT eliminate the problem 100%. You are only eliminating about 20-40% of the hang by only using the RPM adder tables. If you think you are eliminating it completely, fine, but your not, and there more hang to get rid of (and more engine braking to gain
I have tested methods on MANY MANY EVOs around the WORLD.
I am only trying to help you.
OMG really? I know this. Im generalizing to save time but thats not working to well with such a peaky reader lol.
