Basic 'Stage 1' map + launch control + CEL flash on knock

[AndyF]

This has slightly leaner fuel than std, a touch more ignition advance, launch control activated and CEL flash on knock active.

Enjoy but as per usual, please don't just upload this and run it without checking your fuelling and knock levels.

And if your engine goes pop then please be aware that you have used these files at your own risk.

Use it with the attached xdf as well and everything should be then changeable within tunerpro should you want to 'play'

Cheers

hi!

1) just wanted to know if your knock CEL code is a branch from some location...on the launch + CEL, it is separate (at 5C20), while on the ALS launch + CEL it is "connected" to the ALS code (at 5C30).

i want to add what written on this thread:
http://autos.groups.yahoo.com/group/dsm-ecu/messages/3517?threaded=1&m=e&var=1&tidx=1

to this GVR4 bin to make the factory LED boost gauge function as a knock gauge. it is 16bit file...if what's written on thread above is applicable, 1F00 is the location of the knock gauge.

sorry but am really not a :>

thanks for any advice.

Hi Allan,
Yes it's branched from the code location where the new timing value is calculated purely because it was easier to write it into that point as I already had the 'jump' routine into my code.

In theory I could have branched to it from almost anywhere though.

Let me have a look at that thread on the yahoo group tomorrow and I'll have a look/see if I can add it into the code for you etc.

Copy image as a double bin size.. 32k and all you edit is lower image.
This is a code.
5F07: Change DF to 89. DF is an airflow value used for the stock
gauge, while 89 is the address of the knock sum. This is specifying
what variable to load to show in the gauge.
5F0A: Change 40 to 4F. What's happening here is a call to a subroutine
to multiply or divide (forgot which one) the number by a certain
amount. Changing it to 4F will just make it jump a little further down
the routine and divide or multiply by less than stock. This is
basically to scale it down to a reasonable number.
7FA0 to 7FA8: Change from "02 05 07 09 0B 0D 0F 11 15 " to
"00 09 0C 10 12 17 17 17 17".
This is a table used to scale the number to the boost gauge.
Changing these numbers will make a certain amount of knock
correspond to a different amount of needle deflection on the gauge.
This scale works pretty well but it could be a good idea to modify it
to your tastes. As it is, I think it takes a moderate amount of knock
before the gauge will show anything really.

are these all that needs to be changed?
if i wanted to increase the sensitivity, what do i need to do to 7FA0 to 7FA8?
how about using these: "02 05 07 09 0B 0D 0F 11 15 " -->
"00 09 0C 10 12 17 17 17 17" --> "07 0a 0c 0e 11 13 17 17 17"?
thanks again.

To change the scaling of how many knocks to light 1 led Yes. from 7FA0 to 7FA8
For example:
00 is x amount of knock to light 1st led, 09 is x amount of knocks to light 2nd led etc.

[AllanL]

ok thanks very much.
btw, how do i change from 16k --> 32k?

What chips are you burning on mate?

i'm using 27sf512 with burn2 and tunerpro.

thanks!

i do not need to change anything for this string at 5F03 CE FF A0 right?

AllanL, what year and country is your VR4 from ? Would the XDFapply the same to JSpec, Aspec or US Spec ? Does your engine have a Cyclone manifold or not ?

Cheers Mike

This will work with japspec ECUs. For aus spec or us spec it's different bin. You can have the ecu's swaped but you have to change two pins.
BTW Aus spec ecu doesn't have control for the cyclon mani.

its a 92 VR4 RS from Japan, ecu 5808. it doesn't have the intake 'butterflies'.
