fuel cut overrun is turned off and the fuel and ignition tables are both different in the high vacuum/no load areas. i set up the CAN Keypad in LINK Software and enabled CAN DI but i can't seem to get anything to show up in runtime values or anywhere really when pressing the switch on the keypad. The LINK finds the keypad in the CAN Devices tab though.

I have a question that i have not found an answer to on the forums after some quick searching. I have a LINK MonsoonX on my 1uz drift car. I have a pop/flame tune and also a regular tune for cruising around town. I would like to be able to switch between the 2 with my CAN Keypad, is that possible somehow? my main question is probably the CAN programming. I have a digital dash working through CAN and realdash, but i have not set up the keypad to communicate with the ECU, it only communicates with my PMU16 PDM.
Edit: once it's communicating, i have no clue how to do digital switches, any help with that would be awesome as well.

yep we made those adjustments and it works just fine!
-
RIGHT! that's the same thing i forgot on my own ECU as well. we're gonna give it a try and see what happens, thank you!

So we just got my friend's 4g63 eclipse running and idling with a PNP G4x and LINK CAN LAMBDA, but the Lambda controller doesn't seem to be doing anything. we tried stoich mode and auto mode and neither do anything. We have CL Lambda Fuel Corr % open and it says 0.
The CAN LAMBDA is working, it's reading the values correctly but it just won't do any correciton, no errors or anything either. i uploaded the base file we go the car going on.
-
ok thank you very much, i didn't know if i was supposed to use the minimum PW. you're the best Adam!
-
Which number do we subtract what from?
-
also is "battery offset" the dead time table for these injectors on that data sheet?
-
here's the link for the datasheet, https://cdn.shopify.com/s/files/1/0414/1681/8852/files/18U-XX-0088-X_Injector_Characterization_Summary.pdf?v=1618947478
so basically we need way more fuel to get it running? because currently it will not start with a PW lower than 1 which is still making it run rich. crank enrichment needs to be higher? it's using a CAN LINK LAMBDA so i doubt that's reading wrong.
-
just wanted to update, i leaned out the high vacuum high RPM cells even more so now it just pops and bangs and shoots flames all the time. got tired of trying to give it the correct amount of throttle to get it to pop. but holy cow the pops are loud now, i flinch almost everytime now lol.
-
My friend has a 4g63 with a LINK PNP ECU, and we keep getting this error. he's using 1000cc DW injectors with a minimum PW of 1.4 according to the data sheet. however the car idles really rich with that minimum PW set and we're getting that error. are these injectors just too big for 93 fuel?
we lowered the minimum PW to 0.8 and the car wouldn't start even by raising cold crank enrichment a bunch. it currently starts at minimum PW set to 1.0 but the fuel calculation error is still there and the car is idling at 10.8AFR. lowering VE numbers obviously changes nothing since it's at minimum already.

So i finally figured it out, i can now destroy exhaust valves whenever i please. I have a stock 1uz in my SC400 with the IAC removed and just idling with the throttle stop screw around 950rpm, anything below that and it won't idle during cold starts. For the last week i've been trying to get some flames to come out the exhaust, which it used to do on the stock ECU. I'm running a monsoonx btw. After messing around with the fuel values i finally got consistent flames that i can control and they don't just happen all the time. Obviously fuel cut on Decel is OFF.
My timing from 3500-6500rpm is -5
VE table from 3500-6500rpm is 75 which gives me a lambda of around 0.8-0.85. anything more rich than that and nothing happens.
now here's the best part, it only does it when i give it 3% throttle on Decel. if i close the throttle entirely nothing happens at all, which is great i think so it's not constantly just a flame thrower out the back. now i wanna figure out how to get my ECUmaster CAN keyboard to turn Fuel Cut on Decel on and off, cz holy crap i'm just dumping gas out.
i know this won't work for everyone, but if you're dumb like me here's some base values to start messing around with.

I have been asking for help on the same subject, I am have done what has been said, but I also do not get it right
Yea I've given up, nothing seems to do anything. Tried going lean and still nothing as well.
-
I tried 120 and -20 timing and still nothing is happening. Is my closed loop lambda preventing it somehow? I doubt it though because it's reading 0.7 lambda on decel.

Go for a drive with your laptop connected. Turn on snake trails and watch your fuel table during a high speed lift off, take a note of the cells in the table that the snake trail moves through. Most likely it will be the very top right cornier like I have highlighted below. Put much larger numbers in these cells. You will probably get more effect if you also remove about 20deg of timing from the ignition table in the same area. Be prepared for a big hit in fuel economy after this change.
When you say high numbers, how high we talking? I have it set to 102 on my 1uz and -20 deg timing and I'm still getting nothing lol

Realdash updated the app and the analyzer works on android now!
-
Got a response on realdash forum from the dev. said he got it working on megasquirt but there's lots of dropped data. i ordered the seeedstudio analyzer so i guess i'll just wait.

You have to do it manually. For example if you have a LTFT value of 6% in the 3000RPM, 100kpa cell, then go to the same cell in the fuel table and type in "+6%".
Easiest if you set up a page with the fuel table and long term trim table side by side.
oof, you guys should add a button or function to do that automatically lol.
-
once the map has been filled out by the ECU what's the easiest way to apply the values to a VE Fuel table?

I have only personally used the seeedstudio one. Why don’t you try asking on the realdash forum, probably a much larger audience with experience there.
i have asked there, no one has replied lol. i'm gonna order the seeedstudio, it's just backordered, only reason i ordered the other one.

i have now tried 3 different android devices with 2 different OTG hubs/adapters and i'm still not getting anything. i guess i'll go ahead and order the first analyzer that realdash recommends i think it's seedstudio or something?
-
has anyone gotten this specific analyzer to work on android? i see USB Serial, i import the XML file but still nothing showing up. tried 2 different android devices (Oneplus 6T, LG G5). i ordered another OTG cable that people here have said worked for them so when that arrives i'll have something else to try.
i tried an app that is able to read raw can data from the device and i'm seeing stuff come through so basically it's just realdash not working.

all i get on android is Timeout Connecting, no data. however i found an apk that lets me see raw data from the analyzer and it is working. So something just isn't right with realdash here.

i found a driver and got it working on windows, now just gotta get it to work on android
Switching Maps with CANBUS?
in G4x

it's not being controlled by anything, it's just a keypad that outputs CAN data, like every car on the planet, there is no controller, it's a network as far as i understand.
