[SR20 post-dyno touch up]

I've had a pnp s15 link on my car for a while now (s13 w/s13 SR). 

2) Any ideas on what else may be causing the car to breakup under these conditions? My immediate thought was unmapped parts of the VE table but I'm sure there's other possibilities I could check as well.

3) When I log with my laptop it disconnects under high rpm/high load, then reconnects at the end of the pull, rendering my logs useless. This forces me to keep one eye on my dash on one on the... yeah... while I'm doing WOT pulls. It works, but it's not ideal. Has anyone had this problem and are there any solutions?

Just doing a quick search and its Interesting you mentioned these funky issues. I have a pnp S15 on a s13 setup. Im running the same plugs.

My car too breaks up at about 4k and manages to push through it.. IT ALSO drops out/loses comms while logging under high rpm/load as well.

Did you have any resolve with this issue?

FIXED! Got her working.

If anyone ends up googling how to do it here's your answer.

The instrument cluster wiring diagram above shows the solid state logic for the fuel economy gauge. While it was very basic it appears it required vehicle speed and rpm amongst others. So with the car up on jacks, running in 2nd gear, 1100 rpm and 25kp/h, i was able to start inputing the Duty Cycle as i originally wanted.

ECU output at 250hz

18.5% Duty Cycle= 4 on the gauge
20% = 10
22% = 15
23% = 16
24% = 20
25% = 23
26% = 24
27% = 26
Ill be honest and say i didn't test at other rev ranges or speeds. So there may be some more tinkering required in that regard but so far so good.

Thanks everyone for your help!

Ill try and find someone local with an E30 who can help me! cheers for your help Adam.

Thanks for the response Adam.

So with that next step completed I now have a new issue.

"1.2" in the cell maxes out the gauge as just like a Aux Test

"1.1" in the cell brings the needle back to zero.

I had a look at the G4x E36 M50 plugin tune and the fuel economy output for that suggested 250hz.

I thought of this as my car used to run a M50 with the factory ecu and the econometer gauge worked.

with 250hz selected and "17.1" in the cell, the gauge goes back and forth non stop, "18" in the cell maxes it out.

I still cant get it to stop in the increments.

I'm Stumped! Any advice would be much appreciated.

Cheers, Ryan.

Thanks for the quick reply.

Everything you showed me makes sense, no issues there.

How do i activate it at the 10%? Do my settings look correct?

I tried several different % values in the 'GP PWM 2 DC %' single cell but with no luck. Couldn't get the needle to move in small increments.

The gauge still sweeps on the test as it did before. Settings below -

Hi Legends,

Im currently fixing up some final touches on my E30 Sr20 swap. I'm a first time user of a Link ECU or any standalone ecu for that matter, so be gentle. I found the software a bit intimidating at first but I'm really getting into it now.

Below is the econo gauge (l/100km) for a standard e30 - I believe it used injector duty cycle as an input in its standard form.      What I'm looking to do is set it up as a boost gauge.

I managed to activate it with Test (PWM) and it conducted a full sweep.

From what I can establish I need to setup a GP PWM DC table. With MAP as a reference. How do I establish what duty cycle % input I would require to move the needle to each interval on the gauge and moreover how do i set this table up once know?

Any help would be much appreciated!

Cheers, Ryan.
