  1. 2008 Mazda MPS 2.3L FWD Base map

    in G4+

    Posted

    Hey Guys

    Yes it is a Direct INjection car which is why I am looking for a base map to help with HPFP settings.

     

    Adam the CAN information is not important. This car is purely a track car that has ABS/traction control etc disabled.

     

    If I can get the information for the HPFP and Trigger signals I can work from there :)

     

  4. WRXv107+ and coolant temp gauge issues

    still there on web archive. looks like 0x410 on byte 4 according to that blog.

    Looking at the notes i've got from my testing, 410-4, 411-3, 412-0, and 412-5 all produced something that looked approximately like an APS signal. If you overlay all 4 of these on a single graph you notice that 412-5 bottoms out at about 23 (out of 255), so I assume this is either TPS pos or TPS request.

    Also, 411-3 maxes out at 235 rather than going all the way to 255, so again, I assume this is not APS, but is something around torque/tps request as its clearly not actual APS, that I know went all the way to 100%.

    that leaves 410-4 & 412-0 as possibilities. I decided that APS % was most likely 412-0 in my case (2005 legacy) because it was the only one that seemed to follow my attempt at a linear pedal press. The others all had a slow ramp up, which matches the response i'd noramlly feel. 

    Have a look at bit of software called freeSSM (that I didnt know about back when I first did this) that will show you the parameters as the ECU sees them (its a reverse engineered version of subaru select monitor). With this info as well you may be able to correlate the can info better to internal ecu parameters

    you are a wealth of knowledge.

     

    I guess the hardest part about all of this is trying to work out exactly what the ABS module needs in order to stop throwing fault codes so the s drive system will work... I'm hoping I don't run out of transmit/receive channels trying to complete this.

    Is it possible to hook both can 1 and can 2 up on the ECU to the same can network? or no because they both have TR's in them?

    So... the quest to get these subarus going is continuing.

    I am using a Unichip as a Can Sniffer to retrieve this information...

    The first drama I had is that Link uses decimal and subaru can system is hex... so a quick google conversion got me up and running.

    So far I've managed to get the coolant temp gauge working. I've managed to collect vehicle speed from the ABS module and steering angle sensor...

    My next project is to get the "S" drive system working on the sti...

    the next drama i have is that there appears to be either accel pedal or tps info on 3 different can id's that get transmitted from the factory ecu. Does anyone have any further information on subaru can and TPS? the wordpress website for can information is no longer working

    Hi Everyone,

    I have 2 x WRX 2008 models here one is an sti and the other a normal wrx.

    I have used the wrxv107+ ecu.

    Both cars have the same 2 issues.

    ABS light on the dash that I can't get rid of and coolant temp gauges rear maxed out on the factory dash. 

    I have attached the O.e wiring information. It looks like the temp senders feed information directly to the dash so I don't understand why they are both having coolant temp gauge issues.

    Any help would be greatly appreciated. Even if you have wired in extremes or thunders into these later models cars and can shed some information that would be awesome.

     

    Cheers,

    Adam

  9. Link Atom - 4ze1 Trigger setup problems

    in G4+

    Posted

    Hey All,

    I have a holden rodeo which has a z4e1 engine it running a dizzy and im struggling to get my ecu to read an rpm signal. From everything I can find the dizzy setup is the same as an RB30 setup.

    The car previously had a stinger ems unit wired by someone previous to me. So I wired in my Atom ecu and checked that each wire was what it said.. i.e tps signal, signal ground, ect, iat.. all of the above. I re-wired the injectors to have sequential injection.

    Then I got to the trigger setup.. the old stinger ecu only had 1 triger source and the car only has 1 wired into it. My understanding is that the CAS sensor is a 360 hall effect sensor, does the atom need to see both pulse and sync signals to work? or is there some magical way I can make this work without running a new wire to the cas?

     

    ps: the car has custom intake/exhaust manifolds, gtx3076 and seimens  60lbs injectors lol
