It was on 2. I changed to 5 and still does it
-
On the pdm test mode I put it on PWM and it only peaks around 50amps. But I’m trying to figure out how to make the fan PWM on the ecu but I can only seem to achieve this using a GP PWM and use a table . Is there anyway to use the normal fan channel with the hysteresis etc but just soft start them
-
Ok it appears it goes last 60 amps on start up which is the highest inrush current u can set. Is there a way I can have a soft start on the fans to reduce that
-
Finally got back to the car.
have the water pump fully operational with the engine running. Can aux becomes aftive and dc relates to the table
but my fans. If I go onto the pdm and push test. They work no problem . When water temp becomes above the set temp. Can aux for fans becomes active but straight away says fault and red light on the pdm
any ideas what would cause this ?
-
Will the water pump not work via can aux with the engine off like the fans ? Even tho my conditions on my ecu don’t require the engine running ?
-
ok i have progress !
i changed some things but basically ended up changing it back so im unsure what the issue was
now when i turn the ignition on i have 1x fuel pump prime which is the one assigned to can aux 1. the other 2 pumps assigned to can aux 1 status arent working. but i dont have water pump which is on a different can aux. fans i dont know as motor isnt running
ive attached my PDM file and tune file if you could take a look and see what the difference is please
all fuel pumps are working ! i had to change the condition status to inactive and now all 3 fuel pumps are operating. but for the life of me i cant get the water pump or fans to operate. i dont understand what the compound ID is and i think thats what the issue is as thats what made my fuel pump start working
updated file with fuel pumps working
-
Cool well they do say inactive. But the pumps won’t prime or come on when cranking
-
awesome i just updated the firmware
im pretty confident i have no can comunication as if i go to test mode on my fans on the pdm - fans work. my water temps currently at 13 degrees and if i set fans to come on at 10 degrees i get nothing
-
ok disregard the last file i had a few things messed up.
now if i test water pump. it works
if i test fans - they work.
if i test lift pump - it works
but i think i have no can communication and no can auxs are turning on
this pdm file is to what i can see configured how it should be to turn fans and water pump and fuel pumps on via can aux 1 2 3 respectfully.
ive read through the help file on how to get the can communication to work but i cant seem to get it to
-
also i cant make the water pump turn on or make the fans turn on either
have attached my tune file and pdm file if anyone could have a look please
-
so im curently trying to start my car and my lift pump fault codes instantly. for the life of me i cant figure out how to show what the fault is except FAULT- tried running a time plot but it doesnt even show anything when the fuel pump sounds
it also sounds like its PWM when i dont want it to . my ecu is set to STANDARD fuel pump operation
time plot shows 10000 hz and in the output i cant change the frequency
-
awesome thats actually awesome i was hoping i didnt have to asign my ecu to have 4 fuel pumps on 4 different CAN AUXs
thanks thats awesome im stoked
-
ive finally figured out how to configure the razor but have yet to test in the car
i am running multiple fuel pumps. 2 high pressure pumps and 1 lift pump
i have them wired and configured on the pdm as
hc1 - high pressure pump 1
hc2 - high pressure pump 2
adio 5 and adio 6 bridged for my lift pump
in the ecu i have the fuel pump configured as CAN AUX 1
so in the pdm i select HC1 to CAN AUX 1. but i cant select multiple outputs to be triggered off the same CAN AUX input
am i missing something as i want them all to come on at the same time when i prime the engine for start up
thanks
-
Awesome mate big help thank you
-
awesome that is much appreciated info
i will post my proposed wiring for the pdm and see if you think i should change anything around
25a - Walbro 460lph pump (22a according to google)
25a - walbro 460lph pump
25a - 2x maradyne fans (14" 16.9a and 11" 7.4a according to their site)
25a - Ignition coils x6
8a- ecu -ic7 dash-pdm ign switch - injectors -
8a- gps speed module- flex fuel sensor- cam trigger- wideband -vct solenoid- boost solenoid
8a- e throttle supply into ecu (+14v aux 9/10)
8a Bridged for aem 400lph lift pump (16a on google but this will only be filling a surge tank not a pressure supply)
8a bridged as above
8a bridged for davies craig ewp150 on PWM (10a according to davies craig)
8a bridged as above
8a brake lights (all LED) -Alternator light circuit
i think thats all my car needs. if theres any better options u can think of that would be amazing
but i was going to power a switch that when on would turn on the ecu - pdm - ic7 which would be my ignition switch. if im powering the ic7 ecu and pdm and injectors through one ADIO. how would i wire an ignition switch to turn the car on and off ?
ahh would the best way to switch the pdm power supply so when pdms on everything becomes alive. so the pdm power source would be my ignition switch

Was going to power a switch to turn on the ecu and pdm

hello there
i am currently wiring a link g4x fury and razor pdm into a skyline with an RB
just needing to know a couple components current draw so i know which way to pair them up for the pdm
Hitachi R35 coils
Bosch 1650cc injectors
lsu4.9 wideband sensor
aux 9/10 to drive bosch dbw throttle
RB VCT solenoid
hall effect cam trigger (crank is reluctor)
mac valve
gm flex fuel sensor
davies craig EWP150 states 10a current draw. will this change if its PWM driven?
any help would be much appreciated
-
Could the disconnection issue be due to electrical noise ? We have had a similar issue at high loads on the dyno with non resisted spark plugs (and the coils are kind of close to the ecu) it would disconnect the laptop from pclink. But again it was only at high load it would do that . Went back to resistor plugs and issue went away
-
Adam thank you for the support!!
-
It works !!!
only thing different is neutral use to be N but now its 0
-
hey still nothing . the can stuff is above my head so i cant trouble shoot anything . whats wierd is if i go back to my original config it works fine
-
actually found out how to update .
update went good.
ethanol content is working on the dash display.
but somehow gear selection has stopped working on the display and works fine on pc link
-
hello there thanks for that .
for some reason when i go to update firmware the newsest it says i can go is 5.6.7.3631
theres no newer option
now i have it loaded in. and ethanol content is available.. but shows -% on the dash .. on pclink its displaying fine
also now my gear selection is stuck on 1. where as was working fine before. works fine on pclink
-
awesome heres the config file
fuel pump faulting
in Razor PDM
Posted
so success
everything is working . i have PWM the fans from 50% to 100% over a 2 degree span and it works amazing and doesnt draw anywhere near as much current
i currently have them on 125hz and it seems fine but might play around with the frequency
will i need a flyback diode on the fan circuit using the PDM how i am?
