[Which knock sensor setup - 98 wrx - plugin]

Hi all

Got my rex running again, ready for dyno/street/track tuning, 

So i open up the box for my knocklink, read the instructions,

then working out the install  & intergation into the ecu is no worries, its the fine tuning the knocklink as a very novice tuner worries me. I know what pinging, but i am not confinident that my ears will know what there listening for, 

How loud does it come thru the headphones?

Looking at the Knocklink G4 & its self calibration, this looks like a better way to go for the novice.

Note the car will be being tuned by an actually tuner, but i need to know what i am doing  , for track days, cant bring the tuner everywhere, what to be able to check the log after each session

 

thanks again

James

Thanks very much Simon,

had a 15 min window of time in the shed, armed with above info, confirm the sensor worked,

 

it was one of the female crimp connectors, out hadn't latched in the plug and was pushed backwards/ out

sorted that, all reading properly now

thanks again

Also another Q

the new sensor i am running is the same one thats on the IAT sensors page on the link web site

for this sensor what should be selecting

STD Bosch NTC?

 

Thanks

Hi All

Putting my car back together after a year off the track due to engine fail,

the car is running but,

Running the Expansion connector

An Temp 3 is seeing 100c

Same with sensor unplugged,

Same with extension wire removed

Voltage meter across Green/GND & Orange/Temp 3 - 4.96v

Voltage meter on the wires from the IAT sensor - 0.17 (10c or less out side)

-------------

What am i suppose to be seeing across GND & TEMP3

-------

I have An Temp 2 turned off due to reading -40c (sensor in the Maf has failed, but u have never used this input, always used An Temp 3)

 

Cheers

James

Itchn to run this motor in

[Tip on starting setting up Ver 3/4 Subaru G4]

Ok, was the dipswitches, I thought as it was almost running that it would have been them, but

changed them & up she started.

Trimmed the main fuel to 8ms to get it idling in a stable fashion

Got the Wideband wire in, idling @ 12.1:1 so still rich but can drive in & out of the shed

Will do some more reading up on the Quicktune function, but first I'll fit the new IAT,

 

Thanks very much for your inputs

At the moment i am running stock injectors, (grey 380cc ) At the moment,

I want to have car running before i change the injectors (1300cc E85 ready )

Someone has suggested i turn off the IAT sensor & have another crack at starting

But I'll take your advise first & try the master fuel first

 

Once it has started & idles i can remove the manifold for changing injectors & fuel lines, then install the aftermarket IAT then set that up

Hi there

I'll start with - I am a complete novice in regards to ECU install & setup

I was hoping to get the ECU, Extra connector loom, Optional IAT sensor, Knocklink installed & running enough to

drive on to the trailer to get it tune

Already running a Innovate LC-1 Wideband sensor & Gauge, - Need to wire into the Link

 

I have got the link running the lasted firmware,

I have started with Subaru V3-4.PCL file

The IAT sensor is seeing 100c on Ignition (car hasn;t been run for a week & its 6c outside) (causing the ecu to drown the eng with excess fuel on start attempts)

- Is STD Bosch NTC - is this right sensor, (i do have the optional replacement to installed, but i wanted to have the car running before i starting adding all extra parts.0

- MAP sensor - the sensor type is set to Subaru V7-8 - I change this to v1-6 but then the MAP calibration fails

- MAF Sensor - Set to Subaru V7-9 ,But there is no preconfigured option for V1-6 MAF

 

Has Anyone got a better stock Subaru 98 File that will get the car running

DOS screen loads up, ask me if i want to update from 4.8.x to 4.9.3 , select Y , it then

comes up with an error that it can on complete the communcation on COM1-9 fails, with only option to exit,

http://jbondinc.customer.netspace.net.au/WRX/LinkG4%20wrx3%204%20firmware%20update%20error.jpg
