  1. I am looking at setting up EMAP on my RX7 for the next time it is on the dyno to see if I have the exhaust housing sized correctly fore my application, Currently i'm running a Holset 14cm housing and small runner divided manifold. When adding EMAP to a twin scroll setup is it OK to merge the 2 pressure lines in one damper before a single sensor or should they be kept separate? Or is there normally very little difference between each runner and just a single runner can be analysed? Also are the dampers that are used just a canister with muffler packing or are there diaphragms?
  2. I am also interested to see if there is a way to gain access to the unused I/O's on the S6 plug in that currently don't have pins on the main header or XS loom? It seems the S6 rx7 plug in is very limited compared with other plug ins you offer.
  3. Hi. Using INJ 8 I don't get the option of a frequency. Is this port not able to do PWM? and could this have been my issue all along?
  4. Thanks for the help Adam. I'm running a s6 RX7 plug so only have the option to use AUX inj 6 or 8 as they are the 2 currently available. Are there any issues in using 300hz?
  5. Thanks for this. Will this still work with a Hella SSR or will it require a Fuel pump speed controller?
  6. Adam I set my fuel pump output to FP Speed and it would not allow me to select "low" and kept the output high. This kept the fuel pump on all the time even with the car switched off and ignition on. (note the +12V input to the SSR is via a relay triggered by the key being on/ main relay activated) Can you think of any reason it would do this? I have had to set that output to fuel pump and run it normal triggering low side.
  7. Hi All I am setting up my 3 stage fuel pump control on an RX7 with stages injection. The link help file says that I need to set the Inj Duty Cycle that I want to change from Low to Med then Med to High flow. How do I display this duty cycle so I can see it live and can see when the fuel pressure tapers off. And can any one give me some recommendation on a starting point for FP Low -> Med and FP Med -> High

    CAN IO Box

    Thanks, So I should be able to get a Haltech IO box or microsquirt for example and control digital outputs via can? Is link thinking about making an IO box?

    CAN IO Box

    I see that the G4+ can accept inputs via CAN on 3rd party devices, but is there a way to control outputs? The Plug in ECU is very limited My S6 rx7 unit only has 3 additional inputs and no GP outputs on the XS loom. Is a box like this something Link is looking at?

    Fuel Pump Control

    I am looking at running a Walbro 460LPH in tank fuel pump in my 1995 RX7. I don’t think the factory wiring and 2 speed set up will handle such a big pump. I want to keep the variable speed so am looking at running the 33/66/100 PWM control. Will a 25A solid state relay like this work or will I need a Fuel pump controller. Can any one recommend a relay to get?
  11. Hi Adam Thanks for the advice above. I got the ecu running and I got an error on AN5 under voltage, what min and max voltage should I have when setting up this input? I put in 0.5v and 4.5V I also got the same error for AN4 the factory 02 sensor. is this the sign of a dead sensor? My last error was AN2 Oil meter pump position sensor. Is the oil meter pump set up in the bse map? could this be the cause of the error? I didn't start the engine just unlocked the ecu, calibrate the TPS and MAP then loaded the modified base map. Any suggestions on why I may have got the errors?
  12. Thanks Adam Ill change those and give it a go.
  13. Hi I am setting up my G4+ RX7 s6 plug in for the first time. I am trying to adjust the base map to accommodate the changes I have made to my setup before I unlock the ECU and start calibrating as per the plug in manual https://linkecu.com/documentation/RX7S6+.pdf I am no longer using the fuel temp, instead I have changed this to Oil temp and using a bosch 0 280 130 026 sensor. I have changed AN3 to engine oil temp and selected STD Bosch NTC. Is this the correct calibration for this sensor? I am also running Honeywell 150 PSI Pressure sensors on AN5 and AN6 PX3AN2BH150PSAAX. Do I use CAL 4 to set this? The car is running 4x IGN-1A coils in direct fire. I have wired pin 87 to the rear leading coil. And set the ignition mode to Rotary leading direct. Where do I tell the ecu that the 4th ignition output is pin 87? Or is this done automatically? I see when I have the ignition set to Rotary leading direct that ignition 4 is locked but still says AC clutch with a padlock symbol. Also I have moved my AC relay from pin 87 to pin 52. I have changed injector driver 7 to AC clutch is this correct? The final big change is that the car now has 1000cc primary and 1650cc secondary injectors. Should the base may be ok to start the car and let it idle or will I need to adjust some other setting to prevent it from being too rich? My goal is to get the car idling before I take it to a dyno tuner so I can find any little issues now and not when it’s on the dyno and wont start or leaking oil etc Mazda RX7 Plug In Start up tune.pclr
  14. Sorry for dragging up an old thread. I see that on the S6 rx7 plug in ecu it is recommended to use the AC relay as a 4th ignition trigger (pin 87) when running direct fire. Can someone give me some recommendations on how I go about rewiring this? Do I need to run a new wire for the coil trigger from the ecu or use a now unused wire form the harness. If so which wire should I use? And where can I access this in the harness? Also after I unplug pin 87 (ac relay) can I just plug it into a free output? i.e PRC solenoid (pin 7) or CEL (pin 52) or are there any other suggestions?
  15. Im looking at the Ecotrons CAN Wideband. http://www.ecotrons.com/products/wideband-controller-alm-can/ When used with the Link Pug In ECU can the CAN system be used to control when the Ecotrons CAN Wideband controller starts to heat the sensor like the Link Wideband controller? Or will it just read the lambda off the CAN channel? I’m looking at systems that are CAN based but limit heat shock to the sensors
