All Activity

Many thanks, have finally got some noise from the engine from the G4+, now to adjust the tune.

Yes Adam, finally I get the same solution importing "Link Genric Dash" file in ADU. It works , still have some value to link correctly but i'll check better in these days. tks bye

Car is tuned, everything working bar rpm gauge, its series 2 jzx110 2002-2004, originally auto, but manual converted, I sacrificed a/c ;( , still has standard coils yes

https://flooritgarage.ca/blogs/news/link-razor-pdm-decoder Thought I would share here if anyone else would find this valuable. I have installed a few Razor pdm's and am being sent back logs to review and assess, and was struggling to quickly know what outputs are active or in fault. The ECU logs the statuses of each PDM as a decimal value, derived from a binary value where each digit is a status output. So I created a Google sheet that you can take the decimal value from a log and quickly see which output is in an active state. If someone knows an easier way to do this, I'm all ears. Also hoping a version of this gets built into the G5 software in a future update.

The attached will be a reasonable starting point. Enter your injector settings, correct engine size, check base timing and all sensor calibrations. 4AGE Boosted Modelled single throttle Monsoon.pclx

I would also check voltage on pin 45 during cranking, if this drops below about 7.5V the ECCS relay can drop out.

Ahh yes I forgot about not having the choice. Thanks a lot @Adamw!!

okay thank you

All ECU power grounds should go to the same location on the engine, usually on RBs that's at the front of the intake manifold.

Sorry yes, 2 & 4 to D22. I have corrected my original post. The distributor has reluctor sensors so you dont have a choice of the edge in the software.

I thought most JZ engines have the tacho connected to the ignitor. Does it still have the stock ignitor and coils?

so from the header should i run each ground to its own location or can i use a batt neg. stud i have on the firewall?

Thanks Adam. Latest log and tune attached: https://drive.google.com/file/d/16MhOtrrQnJ1GM8GoN_fnRY8yJJ07MMGt/view?usp=sharing https://drive.google.com/file/d/18rv9MHV4kP9CgmubLSF_khE6ufJfqoWS/view?usp=sharing Admittedly since my first post I'd made some PID changes to my eThrottle and when creating the log today, it was performing better. Near the end of the cruise control activation my step downs were a little harsher than the first few but overall an improvement I think. Keen to hear whether you think the log looks normal/acceptable.

At the end, found out the fuel pump is half dead. It runs but not giving enough flow up to the fuel rail. Changed to a new one and works again. What a bad day for having crank sensor and fuel pump dead at the same time.

Hi. I need help, i need base map to start my engine. 7age 20v blacktop Single throttle body tps evo3 Coil on plug Link Monsoon G4X Bosch 1000cc injector Elixir 500lph fuel pump

logs and scope won't show me anything, if you left the wire in then ECU still running after removing your ground pin will be because the ignition switch input would have been active pulling that pin to ground. In terms of ground issues make sure that the ECU power grounds on the engine are securely bolted to an unpainted surface

Pin 16 was left in the header I used a piece of welding wire to poke through the back of the header and touch the terminal, from there I ran a jumper from chassis to pin 16, this left the ecu on even when the car was off when I removed the jumper the ecu powered down. The harness has had unused connectors removed i.e. no power steering, no abs, no ac, no heater No wipers, no defrost it's bare bones essentially. The car was just on a rotisserie for the past year too.. can you see much from the logs? Or scope?

Thanks Adam, I made those changes and it has improved not great but better, I will check the idle stepper is getting "Home" the throttle blade is fully closed, I'll check for any vacuum leaks as this could be contributing.

It might work on 8v, but the OE harness uses 12v shared with cam, crank, and maf sensors, among others. Pin 1 is 12v, pin 2 is signal, pin 3 is sensor ground. BTW I swapped a E36 from S50 to M54 (easier to find uncracked heads), and the exhaust VANOS is near useless. Use the intake VANOS and feel free to leave the exhaust unplugged/unsensored. Confirmed this with Randy at EPIC Motorsports. Might help with emissions, but in terms of power, don't bother.

yeah i wasnt really planning on using an adruino in the imo system,, just was going to use it to sniff the line, seems counterintuitive to wire in a arduino, probably make it easier to bypass if it was found, ill probably just have to set some logic up on some buttons seems like alot less hassle

A quick google shows that the JZX110 tacho signal might be on pin Q20 not Q26 (using pin numbering from Altezza pinout in help manual), have you swapped any pins around to make your JZX110 engine work? did you move the tacho wire to the appropriate place? Do you have the tacho output setup in the ECU? (Aux 3 in the Altezza)

Grounding Pin 16 will power the ECU and engine loom, if the ECU powers up and runs with pin 16 not connected to anything that would suggest a backfeed issue, can you confirm whether your pin 16 not being grounded test was with the pin removed from the header or the pin left in the header? Have you altered any of the factory wiring or added any extra wiring to the ECU like adding a boost solenoid etc?

If you get the serial data working you could hook it up to a digital input into the ECU or over CAN just as a yes/no for ECU Antitheft and you could also integrate it into the starter control. That is assuming arduino doing the talking over serial and then sending a yes/no to the ECU

thanks for the reply,, answers most of my questions, my light does not show up. but i was hoping to utilize the factory immo system, i started working on a arduino binary sniffer for sniffing the serial transmission, not to sure how well its gonna work but ima give it a try, in the case i do get the proper serial data, is there even a way i could use it in logic or something ?

Hey Adam, Indeed. Am looking at exactly that before i go to the track again.
