i have posted tho addres for a 808 map , one it's for IQ and one for smoke map

Sorry, yes you did. Thank you again.

Here is your post:

first map 0E7A96

second map 0E7E1A

in 808 file

the first seem to be fuel quantity on maf reading and second , what we call " smoke limiter"

increase the two map at the same value example the first at 8% and the second at 8% and increase the limiter ............eXample ....1500 point of gain at the maximum value ? .........increase the limiter of 1500 point

the limiter is at this address

0E775A

always in 808

Good information.

I didnt realize you were looking for the torque to IQ map. Did you find it? I believe i found it last night so I will post the address when i get home and can take another look.

One thing i noticed was that it maxes out at 450 N-m on the x axis which is ~330ft-lbs. I am curious if the x-axis(torque) values need to be extrapolated out and increased in order to allow for a "stage 2" tune where you go above this.

usually increase the limiters based on what is presumed to have gained with various increments, however, even if you turn the limiter at 450 nm, but does not increase the diesel, the torque does not increase, then the torque limit may be high and after increases, diesel and air, with a diagnosis we measure the torque gained that it's pretty close to reality ,it is useless to go too high and too dangerous, I hope I have understood your question and I explained , let me know what address you have find , TITANIUM and WinOls are really different , and i can't make work WinOls

The table I found that I believe is the Torque->IQ table is located at 0E7F52 in the 808 Tune. Take a look and see if that looks right to you.

Shape looks correct.
Maxes out at 5400RPM, 450Nm and 108mg/cycle, seems good.
Any other close matches that you found?

sorry , for address , i have made confusion with the file , yes it's right

look at this address 0E7B78

Squeeto · **Posted:** Wed Mar 19, 2014 4:22 pm

It actually looks like both may be incorrect!

0E7F52 has the axis reversed, but the max values are close

0E7B78 has a max of only 2200 where the RPM would be.

Am I wrong?

mmmm i don't know , you are watching in 16 bit Motorola ? I have used tianium for see the address in a 808 , but the driver we have do not see the map , if you open a 811 , you see the map , because for this file ECMTitanium have an updated driver , in 811 the address is 0E71B8 , and it's the same map in 808 , but change the address that is at 0E7B78 , try with Titanium

Titanium calls this Injection (ext.); are you sure that this is Nm to IQ conversion?
Values decrease with increased RPM and one axis is probably load percent.

That 0E7B78 Map in the 808 looks to me like the Smoke Map, IQ limited by Manifold Pressure. 2200 in the x-axis is in millibars and equals ~31psi absolute or 17 psi gauge(as a boost gauge would read). Our max boost based on the boost table appears to be 2335 so that sounds right.

I went through every probable map and your E7F52 seems to be the best fit for Nm to IQ.
I did the Google thing and found other on-line examples where the axis were oriented like our E7F52 so this must be the place.

no I'm not sure ,but i know that two map are important for increase performance , ok , if the second map it's IQ , the first , what is it ? , i know that increase gasoline , based on air value , and the limiter of the first map is after a torque limiter , out of driver , if you watch my tune , you can see it , summarizing the IQ must increased at same manner of turbo , example if the max turbo pressure are setted at 2500 is increased about to 7 % , is the max value for IQ an increment of 7% ? like 2350 ? or I'm wrong ?

If you are referring to the 0E71B8 in the 811, and is the same as the 0E7B78 the 808 tune, it is the Smoke limiter or Injection Quantity limited by Manifold Pressure.

Yeti · **Posted:** Thu Mar 20, 2014 2:54 pm

I think is Injection Quantity limited by Manifold Pressure , i think that the limiter is after the Torque limiter (1) see my tune , (BTW) the two map are close to the MAP sensor and the MAF only work for EGR ?

What i meant was Smoke Limiter otherwise known as IQ limited by MAP. They are the same

Can any answer:
what the maximum peak torque produced numbers for the:
811 ECU/FCV delete + Stage 2 Hot tune?
Stage 3 maximum Hot tune that Yeti mentioned? I may try it after a TC upgrade. :arrow:

I need to know these numbers if possible to order a Torque Converter that will hold the higher torque values in these tunes.

This is what I was able to gather today:
Stock OEM Mopar TC rated for 300 ft. lbs. torque max
Euro Mopar TC rated for 400 ft. lbs. torque max
Suncoast standard CRD TC rated for 600 ft. lbs torque max (Suncoast did tell me they can build one that will hold higher torque values as needed up to 1000 ft. lbs. torque, double or triple clutches, more$$)

Yeti · **Posted:** Fri Mar 21, 2014 4:23 am

if you want more torque , you can buy a Euro Mopar torque converter from Idparts.com , i have see is a reman

http://www.idparts.com/catalog/product_ ... ts_id=3328

but i do not know if is the best of the Buck

my tune do not go over 450 Nm when I make the diagnosis

thanks Yeti,
what is your best guess on what the maximum tune (stage 3) torque peak would be?
I am ready to order new torque converter today, do not want to make a big $ mistake! :wink:

Stock Mopar OEM TC is rated for 300 ft. lbs. max (406 Nm)
Mopar Euro TC is rated for 400 ft. lbs. max (about 542 Nm)
Suncoast CRD-1ES TC is rated for 600 ft. lbs. max (800 Nm)
I talked to GDE, ID Parts, and Suncoast yesterday getting information on the limits of all the torque converters.

Yeti · **Posted:** Fri Mar 21, 2014 8:32 am

not more than 450 nm, I will not do damage example now I'm at abaut 400 nm , in the original configuration when i make a diagnosis , set 375 nm :evil:

and 156 hp , now the diagnosis see 185 hp and 400 Nm , but I'm in continuos set up

I have a question , In the torque limiter (1) , what type of unit of measurement is used?
