ok understood. so it's more or less impossible with a plugin ecu.

good day everyone, have a quick question. could the evo 8 plug in ecu do full staged sequential injection and direct fire ignition? i'm trying to help a friend plan a build and i really want him to use a link plug in ecu any info will be greatly appreciated

i'm using the aem kit with the boost safe wired to a digital input. if the kit experiences an error the boost safe goes to ground. so i tuned without water/meth first and used to 4d fuel and ignition and a 2nd boost table to adjust for the water/meth.

will do just letting the holiday period pass and i'll report back as soon as possible. thanks for all your patience and assistance. it's fully appreciated.

good night everyone, i have an update. so i rescaled the pressure sensors, set over the base fuel pressure to 300kpa and even thou i'm using the fp sensor option in the "fuel system type" setting i switched to MAP referenced and set the base pressure to 300kpa and then returned the setting to fp sensor. i went out for a drive and i saw improvement. i was able to turn off the 4D fuel map because it was alot richer than target. the thing is i still had 150 in the main fuel map. and it was close to being on target. probably a few areas where it was still a little leaner than is should but also had an area as you could see in the attached log. not to be honest the car needs some work on the ignition map so the timing numbers are way to low and this car is seeing alot of boost at wastegate pressure. i did notice that on the tail end of the little full throttle pull in the log it went richer than target which i'm guessing is a good thing. could it be that the injector values for the primary injectors are wrong? its ID2000cc. the secondary injectors are fic 2150cc. i got the injector deadtimes and short pulsewidth adder from ID but i'm wondering if its not flowing as much as advertised aggressive streetdrive 2.llg KGB 7.pclr

thank you very much @Adamw for the support and lightening fast replies. i greatly appreciate it.

ok will do. but this is confusing a bit now. the oil and fuel pressure sensors are aem 150psig sensors, the water pressure is an aem 100psig sensor and the MAP sensor is an aem 5bar sensor. so i'm wondering if my other sensor calibrations are wrong also?

its using an aem 150psig pressure sensor this is the scaling i used: https://www.aemelectronics.com/sites/default/files/aem_datasheet/30-2130-150 Sensor Data.pdf

good day, finally got a chance to go back to the car. @Adamw i took you advice and we re-did all the fuel lines changed the fuel filter and cleaned and flow tested the injectors (the injectors weren't flowing evenly). today i updated the ecu firmware. dropped the fuel pressure to match what i set in the ecu at 3 bar and went for a drive. it was better but still leaner than the target afr once the car went over into positive pressure (even thou the VE numbers are maxed at 150). i tried something to see if i could get the actual lambda to match the target. i turned on the 4d fuel table, set it to always on and i added another 20% everywhere from 20kpa MGP. it worked(see Saturday drive 2 log) . but i am very new to tuning standalone ecus so i'm coming here to ask if that is a strategy that i could employ or is it a bandage/short cut that i should not use? i also attached the tune. also the car is a drag car masquerading as a street car. everything is big. it previously made 1000whp with its last setup. could this car have such high VE? i tried to attach a log before i turned on the 4d fuel table but the file was to big. also any discrepancies seen with the egt was to the egt wires not being fastened properly to the module. any advice guys would be greatly appreciated. evo 7.zip

good day everyone, i'm looking for some advice on when to choose load = tps vs load = map. i've read in the help file that it could be used on a single throttle car with unstable vacuum. I'm doing a project here with a car that has very large and aggressive cams. its idle is around 1050rpm and it vaccum is around -29kpa (MGP). Around there the VE value is around 50. once i go for a drive and the car goes extremely lean the 0kpa (MGP) area. to try to remedy this i start adding VE in the cruise areas. but i end up reaching the maximum value of 150. i know this can't right because we haven't really gone into boost yet. probably just 5 psi at most. I'm probably going to do some mechanical checks on the fuel system to make sure all is good. what i'm asking is would i benefit from going load = tps and using a 4d fuel map for boost? attached is a cal file and a log. the cal file is very rough as this is only my 2nd link ecu tune and the car is a bit extreme. the log file is a little drive around with 150 in the fuel map.

hi All, strangest thing happened to me yesterday. I was going over my mapping because i found that my idle was a little high and i realised that i was my ignition idle control was not responding and the car was idling based on the values in the ignition map. its no real issue but i would like to solve it in case it becomes an issue later down the road. when i turn it off and turn it back on and zero the tables it does not respond to that zero value. it continues to happily idle at the value in the ignition map. has anyone experienced this?

good day, i have link g4+ xtreme powering an sr20vet build. i keep getting a strange/crazy fuel problem when i drive the car and come to a stop. it usually goes very lean. the closed loop lambda would add the maximum set 15% and it would still register lambda 1.2. on a normal some times it stalls and wouldn't start back. for me to get it to start i would end up maxing the VE in the idle are to 150 just to get it fired up. that still woundn't reign the afr in to lambda 1 it would still read lean (lambda 1.2). by this time i would have to hold the rpm up the pedal to keep the car from stalling. sometimes i would get alot of afr swings from lambda 1.2 to lambda .7 back and forth. thinking this is closed loop lambda creating a problem i would then disable it. I am using an AEM x series wideband gauge and using the 5V out and the ground out connected to and analogue input and sensor ground. what i did observe is that when the car is having its crazy issue afr reading on the gauge and on the link software does not match. finally after adding all the possible fuel i can add in the main fuel map, taking off closed loop lambda the car would respond after a while (between 5 -15 minutes) and start idling very rich. this would prompt me to reverse ALL the changes made the car would be back to its original map. has anyone experienced this before. i added the calibration that i am using and a log of both a normal situation and the crazy situation . with the crazy idle log i increased the ve between -100kpa to 0kpa and 0rpm to 2000rpm to 150 then i disabled the closed loop lambda after some time it regularized and i reversed the both changes G4+ Nissan SR20VET-25-5-20-ve.pclr normal operation.llg crazy idle.llg

thanks Adamw. just to be clear i could ground the sensor to the same pin as the shields? also, can the evo 7 Vehicle speed sensor be connected using the same logic? ie ground using a sensor ground even thou it is a 12V sensor

hi everyone, I'm about to embark on my first major standalone ecu project. I'm designing an engine harness for a evo 7 using a link g4+ fury ecu and will be tuning the ecu also. I have one little issue which i cant seem to wrap my head around. the OEM evo cam and crank sensor both have a 12V+ supply. what i'm trying to figure out is do i ground using the sensor ground pin or the power ground pin (if its the power ground pin to i splice close to the ecu or at the end closer to the star earth on the block)? i'm using twisted shielded cable for both sensors. the braid of the shielded should be connected to shield ground?

Hi Senordos, i fiddled a bit more and tried the windows 10 compatibility tester. its initial recommendations didn't really help so the tester probed some more. the second recommendations looked to help alot. i haven't tested it connected to a car but the ghosting of the previous tables are gone

good day everyone. i too am having the same issue. i upgraded to 5.6.6 and it didn't go away. i'm also using the integrated graphics card on my windows 10 laptop. it does work better (but not completely solved) when i put the scaling to 100% but it way to small to view on my 14 inch laptop. any suggestions?

thanks Adam! all this is new to me so sorry if i'm coming across as nagging. your support is A1 as usual and i am very grateful for it! thanks you again and enjoy your day!

thanks again Adam! you provide A1 support! could i get another version of the G4+ storm black sample config? below is what i'm getting when i enable it on my sample file G4+ Storm Black Sample.pclr

thanks Adam for the quick reply, i have one more question. so even thou i haven't purchased the ecu yet, i went ahead and downloaded the pclink software to get familiar with it. when i load up the sample G4+ storm black configuration i see the option to enable the 4D mode and set the table activation but i dont see the actual map itself after i turned the the 4D mode on? Am i following the correct procedure? Also if i load another sample configuration eg the "fury" or the "evo 4-8" and i enable the 4D mode i usually get a prompt and the table appears.

good day, I'm in the process of selecting an ecu to run my (soon to be built) SR20vet project. i am gravitating towards the G4+ storm black ecu. but i have a question? does storm ecu have the ability to do 4D/5D tuning? i'm thinking of using 4D/5D compensation for my water/meth kit that's on the vehicle. can the storm ecu do this?
