Totally understand. I'll do some hard research and see if I can give you an idea of numbers.
-
If this is not something you are planning to do in the near future then we will probably look at alternatives like fitting a 36-1 trigger, or unfortunately, a different ECU.
It is a real shame as the "Mode 2" you have already is the least common by a long way! "Mode 3" is standard on 95% of MG-Rover engines, including those fitted to Caterham, Lotus, Westfield etc.

Bump again...
Customer is debating which ECU to buy right now and it will have to be a decision he makes based on whether we can do the "VVC" Style trigger...

Hi Guys,
Trying to find some replacement pins for the IACV plug on a Mitsubishi EVO.
Pic attached.
Any ideas where I can get the pins?
-
Thanks Simon.
-
Can I bump this? Any luck with adding this in?

Calibration is very different!
This is actually a "modified" Link 2.5 bar sensor with what is meant to be a 5 bar sensor soldered in.
Looks more like 7 bar though! 6.5 bar abs at 4.72v

Hi Guys.
Does this look like a "normal" Link 5 BAR Map Sensor output:
Pressure (BAR) - Volt
-0.5 0.53 0 0.88 0.5 1.23 1 1.58 1.5 1.92 2 2.27 2.5 2.62 3 2.97 3.5 3.32 4 3.67 4.5 4.02 5 4.37 5.5 4.72 -
Hi Scott,
Thanks for the reply.
I read in the blurb somewhere that you can use the VO pin to output a linear voltage related to temperature...
Can you suggest a different amplifier that you know works?

Hi,
Has anybody used a breakout board like this:
https://www.adafruit.com/product/269
So connect an EGT Probe (K Type) to the board, then use the "DO" output into an analogue input on the Storm?
Apparently the output is 1mV/deg C
Any opinions?
-
Thanks Simon
-
So there's no way to make this work?
The ISCV only opens about 1/5 of the throttle travel.
-
Use Cal 1?
I've just set up CAL 1 to start at 0.5V, 3000RPM and go to 4.5V in 12500RPM steps.
Table then goes to 190500RPM

Hi Guys,
I'm installing a Link G4+ Storm onto an Audi A4 1.8T with cable throttle.
The ISCV is part of the throttle body and contains the motor, TPS and ISCV position. Under Idle Speed in the PCL file there are options for Uniploar (6 pin) and BiPolar (4 pin) Stepper motors.
Any clues on how to wire this so that the Storm controls it properly?
Please see attached picture / pinout.
Thanks in advance.

If you want to fire over your map I'd happily take a look at it for you?
-
In which case, go back and speak to the mapper
-
Thanks guys.
All sorted now... Somebody has been playing with the loom before we got the car... They had swapped the +/- wires half way along the loom! No idea why, but swapping them back has sorted the main issues.
3x dead injectors prevented us going any further though....
Lesson to be learnt here - don't take on jobs if you don't do everything from start to finish!!!
-
Sounds like you definitely have a mapping issue...
Where was it mapped, and was it mapped after the rebuild?
-
Hi Scott.
Thanks. Sensor is reluctor yes.
Assuming the polarity is correct (or will be correct), do we have the other settings correct? In other words, should we see ECCS Sync "Yes"?
CAL Table - just updated to latest version and you are right. Thanks for clarification on that!
-
Thank you again Simon.

Hi
I've got a car here that is causing me no end of grief... It's a complete mess of a Ford Escort, converted to Zetec Turbo. 4Cyl, wasted spark, 1 injector per cyl, batch fired.
Couple of Link problems: (Atom G4+)
1) 36-1 Multitooth/missing set up. No cam trigger. Trigger 1 set to 36/1. Trigger 2 set to "sync - none". When you turn it over on the key the trigger errors go up by 1 every engine cycle and the RPM signal goes at 180rpm, but occasionally jumps to 400rpm for a split second. In Runtime Values, the Trigger one is immediately showing as ON as soon as the engine turns, but the ECCS Sync is always no. Is this correct?
2) Water and air temp sensors are the same, from a Ford, and don't show the correct numbers on any of the pre-defined tables it seems. At 14degC the resistance is 44.3kOhms and at 100degC it's 3kOhms. This is outside the range of the user cal tables.
Any pointers to help out with either?
Many thanks in advance.
-
That is the "rarest" of the Rover Modes.
If the trigger wheel is the one pictured, why don't you cut some teeth off and weld some teeth back on and convert to the more common "mode 3"?
-
Thank you Simon - extremely helpful as ever.
It would be great to put that information in the help file...
Here's another one for you...
If you are starting with a "map" from scratch - ie you have no base file - how would you recommend setting the Master Fuel Number?
We tend to guess it and just go low, then increase it until the engine fires... But surely there is a more scientific way?

Hi,
We have always done cars with sequential before, but on this particular application there is no cam trigger, so we are running the car as "multi pint group" Injection mode.
I'm unsure from the help files as to which injection rate to use - 1/2 or 1 Engine cycle?
It's a 4cyl Turbo car with fairly small injectors, 36-1 crank trigger, one injector per cylinder, wired one injector per output on an Atom.
Can anybody give any advice?
Delay Coming off Throttle
in G4+
Posted
Had this recently on an EVO 6 plug in G4+.
Stepper position for a stable 1000rpm idle was 92+/-2.
As throttle was applied to pull away, in real time, the stepper was jumping to 60ish steps (opening the throttle more), which meant that idle was at 1600-1700rpm. It then took about 30-40 seconds for the stepper to close to 90 and to come back down to 1000RPM
So in stop-start traffic the car was a nightmare.
We had to change loads of parameters, but I'm still not happy with it if I'm honest. Still jumps to 60 steps on light throttle appplication, but managed to get it to drop faster.
I can't see why it's doing the drop to 60 steps! I've not told it to, so it's got to be hidden somewhere.
