    Closed Loop Lambda control and Mixture Map

    The problem you have is that the mixture map is using the AFR Lambda target table to work out what fuel ratio is required and where you are getting the spikes you have no direct relational axis so it has to guess, once you have a base tune use the mixture map and get the axis of the AFR table in sync where you need to tune it better and don't correct the sites you have already done. Also turn off Lambda correction and overrun fuel cut while tuning or you will get no-where.

    Lambda 1 vs AEM wideband

    Yes, its there for that exact reason it will also mean that Lambda 1 is Stoic.

    Lambda 1 vs AEM wideband

    As a note UK pump super unleaded fuel is 14.4 Stoic as is most fuel worldwide where Toluene is used as the octane booster.

    Problem boost closed loop control

    Boost Targets are Absolute, because of this I find it easier to do all the boost control settings in MAP.

    Problem boost closed loop control

    You have a target of 150 and are making target pressure, do you mean to set your target to 250 (1.5 bar of boost) ?

    Problems With Impreza WRX 2000 GC8

    Check the trigger with the built in trigger scope (ECU Controls - Trigger Scope), save a log and report back here.

    Spark plugs

    Difficult to see the plug looks old but there is a lot going on, the plug is to cold, the timing looks too advanced and the fueling looks ok, you say 11.3:1 but you haven't said what fuel you are using.

    Engine hesitation after retuning

    The idle ignition table should be a lot smoother than that, they 4 degrees a cell up and down from 0 idle error, also lock out the idle strategy while the vehicle is moving.

    Lambda 1 vs AEM wideband

    I have this in my spreadsheet from the AEM Manual: (2.3750*Volts)+7.3125 so (2.3750*2.15)+7.3125 = 12.41875

    Lambda 1 vs AEM wideband

    With 14.7 Stoic 2.15v should read 0.844

    3sgte unstable ignition

    Move your cam trigger slightly.

    3sgte unstable ignition

    You have noise level breaking through your trigger arming threshold. You have this set to 0.3v on both your signals: At idle crank the noise floor only very slightly above the 0.2 you are seeing I would raise this to 0.5 at 0rpm for both triggers On Idle the noise floor maxes out at 0.5 which is above the noise level and may been seen as a trigger I would set the arming threshold to 1 at 1000rpm As mentioned about the trigger points are near overlapping need to get this much more in the center.

    Pressure sensors reading downward

    Ground and +5v wired the wrong way around maybe, but I actually though they had red and black wires for feed so I would hope you got that correct, could be the calibration you will need to use CAL 4, 5 or 6 and set it like this:

    Vvti setup errors

    Lowest is 174.3 stick that value in the offset and retest.

    Deadtimes base maps.

    In my opinion Dead Times are overrated (a great starting point) because they are actually only correct for the same environment they were tested in, your be better off just tuning it and then looking at the bottom of the map and seeing if the bottom line does not look right, if the deadtimes are not high enough you will have an upturned map at the bottom, to check the linearity of the deadtime table disconnect your alternator and monitor battery voltage against AFR and adjust as the voltage drops and adjust as required, for voltages above your max alternator voltage just keep the table linear.

    Lambda 1 vs AEM wideband

    This is not something you should leave to chance, it is very common for the AEM output to be out from their calibration, the BEST way to check these is with a Link CANLambda and plot them both together in the graph, this is something a good dealer will be able to do for you, or of course just run the Link CAN Lambda and get the many benefits that come with them.

    AC problem FD rx7, LINK G4+ plug in

    Did you try turning the pull up resistor on as mentioned in my above post ?

    Link display

    It's a beauty, unfortunately not worth much at all.

    AC problem FD rx7, LINK G4+ plug in

    The Air con switch requests the air con be engaged via DI3 - First thing to do is try it with the pull up on as in the attached picture. If you Press F12 and look at the status of DI3 does in change to green? if so does it change to green when AC Request is on ? if not then change the on level to high. ----- The Air Con Clutch control settings under Chassis and body may also be set wrong, if the inj duty cycle is above 35 then it will switch off, so if you have your master fuel set low and your above this amount of inj duty cycle it will also not work.

    Gdi spill valve energized +5v

    Do not worry for some reason they have chosen to show the drive circuit, your valve is a derivative of the Bosch HDP Series and the MSV valve is a current not voltage based device, you will need to wire it in accordance with the GDI manual and this is one we can control quite well.

    Link display

    Which one is it Neil? the Original RT ? over xmas RT Pro was selling for around £600 new, I have a few friends who recently upgraded and sold off their earlier non pro versions for £250ish, the pro £350ish The new dash is superb !

    Aim MXS dash

    Just to add all the current MXS Strada Dash's out of Aim are now 1.2 in the UK and will Transmit and Receive on the same CAN port.

    Cal table resolution

    AEM's are in fact terrible i have had 2 exactly the same gauges here this week both calibrated differently and not by a small way, their sensors are also not bosch and fail very fast.

    Internal or External MAP?

    As MAP is a reactive measurement rather than a demand based measurement you actually want some damping, fast changes are made based off throttle position. You can choose a long pipe where it may react slightly slower or a long run of wire which may induce interference the choice is yours.

    Ethrottle Idle up with AC

    Set an Aux Out as AC Clutch anyway, even though its not connected it should still work for idle up.
