    As far as I know nothing has changed related to the gear detection code for many years.  Lets start by attaching a log of a short drive and your tune.

    It's weird as the gear indication/ detection has been fantastic up to now. I'll download a log when I get 2 mins and post it up. 

  6. Evolink gear detection issue

    in G4+

    Posted

    Is there an issue with the latest firmware as my gear detection (displayed on a Plex uSDM 100) has now got a huge delay and seems erratic after the update. Previously this was working brilliantly (for the last 2+ years and every firmware in-between).

    I haven't tried to reload the firmware or relearn gear detection as it does seem to display the right gear, eventually. 

    As a complete side note, are there any benefits of upgrading from my G4+ to G4x platform? Specifically more digital I/O would be a great benefit for my application.

  7. Modelled fuel critical settings

    Sorry for the late reply and thank you for coming back to me.

    Can you outline the benefits of going to VE from traditional? I don't currently plan on running flex fuel, which is what I gather the main advantage would be?

    I had a fiddle and the fuel map seems to keep the profile from the traditional map, is this typically correct or will the VE map profile likely be quite different- I appreciate thats a subjective question, but generally speaking does it following the same sort of shape? 

    Is there anything else to consider when deciding whether to use traditional or VE?

    Thinking about changing from my traditional map to a VE based, how critical is the cc field? I don't know the exact displacement of my engine, only that its stroked to 2..2 from 2.0. Anything else to consider when changing from traditional to VE?

    You are correct, on the Evo9 plug-in the tacho is driven direct from a circuit that gets its signal from the crank trigger.  This was done to save an aux output as the evo is particularly hungry for aux outputs.

    You will be able to make Inj 7 drive the tacho but there are a couple of gotcha's...  Inj 7 is connected via an internal circuit to DI7 & Ign 8 so you wont be able to use these for anything else - they will have to be set to off.  Inj 7 doesnt have a pull-up resistor fitted like most auxes do so you will need to add your own pull up resistor to +12V.  I suggest a 2.2Kohm.  Pin 59 is a switched 12V so that is convenient.  Something like this:

    Missed this reply, big thank you for coming back as I wired it up last night and was scratching my head about the IC spray light coming on with the revs! Didn't have time last night to look into it but had a feeling that maybe there was an internal connection in the ECU- which kinda makes sense, as those 2 outputs and 1 input are all to do with the IC spray button, pump and light. I currently use DI 2 to latch up and switch maps and want to keep that feature. 

    I'll use one of the idle control outputs as I've not got the stepper and I'm very unlikely to ever fit an OE one in the future. Will I need to install a pull up resistor anyway? The tacho was working on Inj 7 I guess there is an indirect pull up from DI 7 which obviously won't be the case on one of the other aux's but do I really need it as it's switching to 0v?

    I have the same configuration in my Evo 8 with Thunder...

    12 tooth crank trigger wheel and i removed the large tooth from cam trigger wheel.

    Nice one, how did you operate the tacho? I assume you did what I'm proposing above, which is taking the Green White from pin 45 (if you had a 3 plug ECU to start with?) and put it on a a high PWM output? Really annoying I can't see the tacho wire in the diagrams I have.

     

    Scratch that, just checked another set of drawings and found it. No other circuits shown on that wire, so I'll be putting that into the place of the IC spray output!

    Holy thread resurrection time.....

    I have literally just installed an 18-1 trigger wheel (cam belt was due, at least that's my excuse!) and removed the small tooth from the Cam trigger, set base timing to 130 and she runs. Only issue I now face is that the tacho is reading literally off the clock. Having looked through the workshop manuals, I can't see the tacho wire (green white ECU pin 45) in the drawings at the ECU or anywhere else to ENSURE it doesn't go anywhere else/ do anything else before I move it.

    I suspect that the crank signal is internally looped within the ECU from 43 (Crank) back out on 45 (Tacho)???? The fix is easy enough, in my mind, which is to move pin 45 to pin 56 (Injection 7, was IC Spray motor which is long gone) and job's a good 'un. 

    BEFORE I do that, can anyone confirm the above- as I would hate to move it and find out it feeds something else and cause a world of pain...... 

    Plus side, I'll be able to have a taco sweep at key on now :P

     

    Edited to add- I've removed pin 45 (Green White) from the ECU and run the car, no issues which supports my cunning theory about being internally linked....

    Dear Adam

    Thanks a lot for your answer

    I will start to prepare one with Map axis

    It is well worth using the runtimes window (press R when connected) to check the Mivec position is tracking the target from the VVT table as you may find you need to fettle the input settings if it doesn't track/ change. There were a few other minor anomalies with the base map and my UK Evo 9. Nothing too crazy, but spending some time using the "test" feature on the outputs and runtimes window to verify inputs will be time well spent. I also used MGP to scale the axis with RPM as MGP accounts for barometric pressure, but moreover I prefer the scale it offers.

  15. Questions about the capabilities of a WRX9+ G4+

    in G4+

    Posted

    As others have already said, can't you achieve your aim primarily through boost control? If you have DBW throttle then again you can control/ limit power with that. 

    So far as I understand it, and I am far from an authority, reducing power by altering fuel and ignition maps isn't the way to go as for one reason, retarding ignition will generally increase EGT. 

    To answer your question on hardware, the PNP ECU is the same as the Extreme. It may have some additional I/O and probably an on-board MAP sensor over the loose Extreme ECU. 

    Hope that helps?!

    I'm down in Pulborough, far from a pro, but have been playing with Link for a while on my Evo. Happy to give you hand if you're just wanting to get the car running- and would be helpful as I keep trying to get my mate to let me rip out his P8 ECU and fit a Link. 

    Drop me a PM if you want, no hassle if not :-) 

     

  18. Where to buy cable.

    Depending on the location you're intending to use the cable, PLC Hookup wire (0.22mm2) may also be worth considering, especially for the expansion port plugs and short runs inside the cabin.

    Its unable to on a generic option. either tooth can be removed.

    Are you on a plugin unit or a wire in.

    One thing to consider on the plugin is that the Tacho signal is driven from the crank signal so if changing to a high tooth count you will need to move the Tacho signal on to a free AUX output.

    Thank you for the reply. 

    I'm on an EvoLinkIX PNP.

    Great point on the tacho, suppose one benefit if I were to have to relocate the tacho output to an aux I could take advantage of the dial sweep on ignition! I'll have to check the wiring but a really good point. 

    Completely on the fence now whether to spend the £100 odd to convert to a multi-tooth trigger wheel. 

  20. Crank trigger tooth count

    Posted

    Thank you for the reply and advice. 

    Yes, Evo 9 Mivec. I am 99% it was to do with the ECU itself rather than a generic issue, just thought I'd ask before causing myself a problem! 

    That's interesting about taking a tooth off the cam sensor trigger, without wishing to sound really silly, can the ECU not account for the 2 generated signals at the Cam sensor? 

    Would it matter which of the 2 teeth is removed, one is a lot bigger than the other? 

     

    Found this thread earlier, question answered.

    Belts are due on my 4G63 soon and I was wondering about fitting a 12-1 trigger disc, is this worth doing or does it depend on other factors? Car is around 500hp and has Mivec. Are there any tangible benefits to doing this??

     

    I did read on another platform that there could be an issue with controlling Mivec with an aftermarket disc- can't see why as the ECU just needs to know where the engine is and therefore what position the inlet cam needs to achieve- sure the Link will handle it :) 

  22. G4+ Evo8/9 Plugin - XS Loom Digital Inputs for Ethanol Sensor

    in G4+

    Posted

    Without looking I don't know if you can use an alternative XS input for this sensor, but if the manual says you can't then that's more than likely the case.

    The ECU pins are available in the US new from SpoolinUp (Matt is a great guy to deal with and posts internationally) or you can go to the scrap yard and find a vehicle you can cut the plugs out of to re-use the pins? They're pretty easy to pop out and re-locate as necessary. 

    DI 1  could be used given that you don't have MiVEC and if you're not fussed about the Auto IC spray so could DI2, as I suspect DI1 won't have a wire in it if you've an 8? 

     

    Hope that helps- but I think all I've done is reinforce what you already know!? :) 

  24. Wasted to Direct spark effect on Dwell times

    in G4+

    Posted

    My little brain has been thinking and I wonder if anyone knows the answer, I'm particularly think of the 4G63T engine and ignition setup. 

    Lets say you start with a standard wasted spark system with 2 coils and the dwell at 14V is 5.5mS. 

    You then install a wasted spark COP system and are told to set the dwell at 14V is 3.5mS, as per the coil's data sheet for direct fire use.

    You then modify said kit to run in Direct spark and leave the dwell at 14V, 3.5mS. Now this is where I start to wonder about the dwell time, does the ECU reduce the dwell time to each coil, or has it unintentionally doubled because the coil is firing half as often? On the flip side should the dwell time be doubled when running in wasted as it's firing twice as often? 

    Hope this makes sense, I guess the basis of my question is asking how the ECU applies the dwell in wasted vs direct spark. I would assume that in direct spark the coil sees the programmed dwell but is this the case in wasted?

    I may have completely confused myself, if so, apologies. 

  25. G4+ and Thermocouple for EGT

    in G4+

    Posted

    Thanks for the replies, the board has arrived so I'll do the modification and see what the result is I can compare it to my Defi. Certainly been interesting as I didn't realise thermocouples generated a voltage, rather than a varied resistance as with an IAT, etc. Every day is a school day!!

    Cheers
