dx4picco Posted June 12, 2020 Report Share Posted June 12, 2020 Hi, Is there the possibility to use a DI to dictate if the overrun fuel cut is on or off? I have for example on DI 2 my high boost map, and I would like to turn off overrun fuel cut when DI 2 is on, but still keep it activated the low boost map. thanks for your input!

Adamw Posted June 12, 2020 Report Share Posted June 12, 2020 Not the over-run fuel cut function directly but two ways you could achieve this: ORFC is disabled when antilag is enabled. So you could enable antilag with DI2, but set antilag enable RPM to something like 20000RPM so it never activates, then it will just be used to turn ORFC on & off. You can turn off the native ORFC fuction and instead use a GP RPM limit. Use a virtual aux on one axis, RPM on the other. Set the activation conditions such as TP<0.5% and your DI2 switch in the VA.

dx4picco Posted June 13, 2020 Author Report Share Posted June 13, 2020 sounds good! Would something similar be possible with with the closed loop lamda? Namely disabling it if DI2 is active 'on high boost map)? Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 13, 2020 Report Share Posted June 13, 2020 The Antilag will disable the CLL at the same time. Quote Link to comment Share on other sites More sharing options...
dx4picco Posted June 13, 2020 Author Report Share Posted June 13, 2020 setting the AL enabled RPM to 20000 and turning the DI on does indeed shows status "AL armed, under 20000rpm", but CLL is still running, this was tested at idle. edit: neither by normal drive with AL on and -20° trim https://drive.google.com/file/d/1zlNIm2-YlKJxbNX-0iCIjz5nB9lBRXh-/view?usp=sharing Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 13, 2020 Report Share Posted June 13, 2020 Hmm, maybe it only disables when antilag cut is active, I cant remember. Another option is set your CLL FTrim tables to 3D and put DI2 on one axis. You can then specify zero trim when DI2 is on. Quote Link to comment Share on other sites More sharing options...
dx4picco Posted June 13, 2020 Author Report Share Posted June 13, 2020 I'm gonna try that too. thanks. another question, I am struggling alot to tune the fuel on my top row (13-20 KPa MAP, closed throttle, coasting). I cannot get a replicable lambda/afr there. I've tried injector timing from 400 to 270°, tried target lambda from 0.9 to 1.0, tried igntion angle from 34 to 8° (btdc). every single time there is no corelation in the result. I can add 10% fuel (VE) and get leaner lambda, then retry and get 5% richer. Anything I didn't thing about in this special area? (ej20k, standard timing on the cams, stock cams) Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 13, 2020 Report Share Posted June 13, 2020 13-20kpa is over-run rather than coasting. Lambda is irrelevant in that area, you have very unstable combustion due to so little oxygen in the chamber. You are probably also working in a non-linear region of Injector PW so that gives you even less relationship to commanded fuel. Quote Link to comment Share on other sites More sharing options...
dx4picco Posted June 13, 2020 Author Report Share Posted June 13, 2020 I'm struggling getting the tip-in/accel enrichment right in that area (feathering the gas 1-2% tps) and a small stet to 10-15% tps would jerk hard, and I thought the initial problem was that the base lambda i'm running in that region is bad.

dx4picco Posted June 17, 2020 Author Report Share Posted June 17, 2020 next question regarding flex fuel. On another car, I've got a ecumaster flexfuel sensor (looks like its a continental one according to whats writen on it). But I cannot get the ecu to read ethanol content. I always get "error" as ethanol sensor status. its been wired like that: https://drive.google.com/file/d/13fRntogaVVgccpY8X2hV0I9Qj3WSL-F7/view?usp=sharing red has +12v when ignition is on, black is chassis ground and white is signal on DI2 from G4+ atom, continuity on each wire is checked. did I miss something on the software side? map and log here https://drive.google.com/file/d/130WH7JeeUkstY_OE5ycceLDMcGcAJaHc/view?usp=sharing https://drive.google.com/file/d/1ookjKJQX0AtEvK8mt6NDS2fUpcmLUBe8/view?usp=sharing Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 18, 2020 Report Share Posted June 18, 2020 Looks like you have the wiring reversed to me, its normally moulded into the housing: dx4picco 1 Quote Link to comment Share on other sites More sharing options...
dx4picco Posted June 18, 2020 Author Report Share Posted June 18, 2020 Hmmm okay, the instructions delivered with it were like it has been wired. But I will give it a shot. Quote Link to comment Share on other sites More sharing options...
dx4picco Posted June 19, 2020 Author Report Share Posted June 19, 2020 Well, it seems like the indication on the box were wrong and swaping vcc and vout did solve the issue. Quote Link to comment Share on other sites More sharing options...
dx4picco Posted August 25, 2020 Author Report Share Posted August 25, 2020 Hey, Two more addition to the list. -What can cause wastegate flutter? stock EJ205 with TD05, openloop boost control with fixed duty, brand new pierburg 7.01024.02.0 solenoid. When I'm giving it the beans in 4th gear, MAP oscillate around, lets say it should be 1.15 bar from 3750 up, but I am getting a wavy pressure with 0.1bar +/-. For me there is no reason for that as every parameter is fixed . I tested solenoid frequencies from 20 up to 45 hz with no change in that behaviour. There are no apparent boost leaks (nothing to be heard) but no smoke tester available . -On a subaru classic v6 (same car as point 1), it has a stepper motor as idle control I believe (6 wires iacv). I acquired a storm+ and I am wondering how the hold on power is wired on the stock harness. What is the hold power pinout on the plugin version for example? Is it aux-inj 6? I cannot seem to find the corresponding pin on the harness in the manual (http://linkecu.com/documentation/WRX6+.pdf or http://linkecu.com/documentation/WRX6X.pdf) So That I can make my new adapter including this function and allow the iacv to reset before shutting down ecu Cheers Quote Link to comment Share on other sites More sharing options...

dx4picco Posted August 27, 2020 Author Report Share Posted August 27, 2020 Just thinking out loud, can this oscillation in boost pressure be due to compressor surge? I am not hearing any special noises but could it be? Quote Link to comment Share on other sites More sharing options...
Adamw Posted August 27, 2020 Report Share Posted August 27, 2020 It could be surge or the BOV or the wastegate, which is why I suggested unplugging the solenoid then you can rule out the ecu causing it. Quote Link to comment Share on other sites More sharing options...

dx4picco Posted September 5, 2020 Author Report Share Posted September 5, 2020 on WRX4 and WRX6 plungins, CAS and CPS + (power) is 5V or 8V? to know on which pin I should wire it to on the storm black Quote Link to comment Share on other sites More sharing options...

dx4picco Posted September 5, 2020 Author Report Share Posted September 5, 2020 so pin 136-23 goes onto sensor ground? Quote Link to comment Share on other sites More sharing options...
dx4picco Posted September 13, 2020 Author Report Share Posted September 13, 2020 If the ignition switch is now controled by a hand switch and not the key anymore, does it allow to get rid of the ecu hold power function? if I switch the DI off, then it cuts ignition and fuel, engine stops, but ecu still have power because the key is on further position. Does the ECU initiate directly the stepper motor reset after engine stop? (my00 impreza) edit: is there a way to make a rotary switch for ALS to interpolate between 2 tables? only found switching between two tables.
