hi all

i cant log adc/ayc/abs whit evoscan
id all so like to bleed the adc/ayc

im using evoscan 2.8 and have a 1.3 and op2 cable both not working

i have pin 9 cut out of the 1.3 cable
pin 1 and 15 on the 1.3u cable are linked

iv all so checked that pin 46 adc plug is linked to pin 1 odb plug
and all so pin 35 adc and pin 7on the odb are linked
on the cars odb plug pin 1 is there and pin 15 is empty

the car is my evo7 but i could try get a e8 and a mates e7 to test on

any help would be great
neil

 

bump this up has any one got this to work ????

 

In EDM evo 9 yes, works perfectly with 1.3U. Have you selected ACD from drop down menu?

 

yes have selected adc but still not logging

can you tell me can the pump pressure be logged

any have the pin out for the odb2 plug

thanks

 

Yes, you can log pump pressure, see acd mapping thread at geekmapped. But you cannot datalog pressure what acd clutch is seeing, only accumulator pressure. I guess you are mapping your acd and you would like to datalog that pressure too to see what effect your changes are causing? Accu pressure can be used to estimate how often pump runs with new settings.

Bleed nipple at ACD could be used for pressure gauge connection but it would be nice if there was any free analog inputs at ACD ecu and some pressure sensor could be connected to ecu for datalogging. Does anybody know if there are free analog inputs in acd ecu?

 

yes im working the adc ecu and trying to work out afew things
i would like to know how good the pump is too ie normal pessure is 17 to 20 bar so iv been told

i like what your say about the pessure sensor

iv been reading as much as can on it here , gm and other sites
but not alot of info out there

 

Normal pressure range is 11-15 bar (lower and upper boundary) ie. pump stops at 15 and starts again at 11bar (4 bar hysteresis), the time it takes to rise pressure from lower bound tells something about pump, yes, but you need some known time from good pump to compare.

Mapping you are doing is not rising this pressure but pressure in acd hydraulic pipe instead and thats why to see effect of modifications one more sensor would be needed. As you know processor is the same as in older evo's so there is many analog inputs but don't know if these are "wired" to ecu connectors. It would be nice if they were, or atleast one.

 

thats some good info about the pump
do you know what sort of time it takes to rise the pressure from the low to the high point , on a good pump

i see there is only one ayc map for all 3 settings or have i missed some thing

 

I remember I have taken some datalogs from my own car (if 30000km driven pump can be considered as good example) but don't know where those logs are. I will try to find out and I let you know.

I think there is only one AYC map but I'm not pro with these. You are right, not so much info out there about mapping these ecu's

 

did you have to do any thing to your cable to make it log
if you had some logs that would be great

 

No, just standard 1.3U with pin 9 removed.

 

Ok, I have one idea for your logging problem as I played with my bench acd ecu. You need OBD pin 1 for datalogging, if that is not connected logging does not work.

 

il have a look at the car and the cable and see what its got

 

so pin 1 and 15 on the 1.3u cable are linked and have pin 9 removed

on the cars odb plug pin 1 is there and pin 15 is empty



got this info off gm

The same in my cable but I don't know about car OBD plug, I just needed to connect my test bench ecu pin 46 to OBD port pin 1 to make datalogging work. And I noticed datalogging only works with 1.3, not with 2.0.
