Would it be possible to make a simple "A-B-C" downloader app for windows or (mobile preferably, i'm sure it would have some hardware constraints) to help out some who setup ECU's ,tuners or shops. To retrieve only logs out of the client/customers ecu's for clients who have no knowledge of PClink software? just for those day of racing where theres a problem and no laptop around. A IOS/Android app would be amazing with some form of hardware interface

This might be a wild one..(also super crude understanding of can bus) Possible to add a can sniffing feature to PC link (Live stream) to identify address, frames, checksums and all. Ex. Bench powering a G4X>Feeding bus signal from OE Car to G4x Bus> logging or streaming in PClink. To decode and replicate on car new ecu is installed on? I guess it would turn the ECU into a tool at that point instead of buying a Arduino or can sniffer and supporting software. It would be all natively supported

Well done !

Both worked perfectly EPAS woke up instantly , looking at the frame it looks a little more complex than just sending engine speed. Appreciate the help Adam!

It's on CAN 1

much thanks Adam, Cal file attached. Corolla-EPAS_V1.pclx

Update: Finally wired it in and 500kbps is the bit rate. but still no wake up from EPAS from original stream and frame setup, i have found a little more info but... how would i translate this on the CAN setup streams and frames? -if there is a checksum would this just be something that cant be produced on the G4X ? - Could i possibly run the same canbus ID for RPM from a GT86 if any info is available since its a more supported platform. Some findings "below is an example of the rpm message {2C4 8 0E 1B 00 19 00 00 92 A2}2C4 is the message ID and this one happens to mean RPM.8 is the message size, it will send 8 additional pieces of info.0E is the first piece of info. In decimal it means 14 ---Protip-the stock calculator app in windows can be changed to "programmer" which allows you to input HEX numbers and it auto translates into decimal.1B is the 2nd, and it translates into 27Now those two bites alone don't help or add up to anything, but if you put the HEX together (0E1B) it translates into 3,611-which is the actual rpm!I don't know what the "19" or "92" mean yet, but the A2 should be the checksum at the end.To calculate the checksum, it helps to know that the message ID is actually two bits, IDH = 2C and IDL = 04. So to calculate it, add(in HEX calculator) 2C+04+08+0E+1B+19+92 = 1A2" Wish i had a car to scan live

So STP and ELS(Electric load switch) are just DI's. Factory ELS is a idle up not sure but i also think STP is one also, If you have closed loop idle on and tuned right in open loop you don't really need either. but if you want to use them you can. if you are running E-throttle, you would need STP for cruise control cancel.

Sweet. Thanks Adam! would have to send the unit in for AUX 9&10 still? or did they change that for the G4X plug in board and the text stayed the same in the manuals ?

Hi, im currently repurposing a TST205X to a 2zz-ge and was wondering if the Pin 27 (G-). is actual ground or sensor ground?. i know Toyota typically isolates and shares the trigger grounds together. Just wanted some clarity on that. Case use is for the crank (Trigger 1) and cam (Trigger. 2) grounds. Edit: Also if i am using VVT for Aux 1 can i still use the E-Throttle external controller in another pin?

Ok ill give it a try with that recommended stream and tinker Thanks Adam!

OK, i know the bit rate is 500kbit/s Once it's all powered if the stream isn't right would the fault show in the runtime ?

Working on calibration setup and still in a learning curve for CAN. So retrofitted to the car is a Toyota Yaris EPAS. Currently the EPAS ECU need VSS from 0-5V and RPM signal thru CAN to start assist when engine is turned on. I currently have the VSS wired to it but now i need to get the Engine speed stream going VIA CAN. Ive looked at the CAN ID but not sure how to program it. http://opengarages.org/index.php/Toyota_CAN_ID CAN ID (Decimal) CAN ID (Hex) Data Length Description Rate (seconds) Notes 708 2C4 8 Engine Speed 0.02 Bytes 1 and 2 Snippet from another forum who used a CANdo Device "The end result looked something like this 2C4 8 06 8A 00 19 00 00 92 09 Repeat rate 20 ms(milliseconds) " Any help or slight walk thru is appreciated !!

im gonna give that a try! Thanks Adam ..... person question do you ever sleep !! LOL

I added 30% to the VE on table 2 (not in the calibration attached but as a test) and it seem to correct it but maxed out VE map. i think its incorrect injector data but not sure.

Sorry about that. So if you look at the fuel table 2 its almost maxing out on the high end, if i were to add 30% it would be maxed out. i compared the injector PW from 91 log and e85 log and it went from 1.2ms to 1.6ms around 2740rpm -2.5 psi map pressure. thats where i got the 10% from I'm looking over the data and seems right, unless i entered something wrong somewhere. I attached the AEM Template. Is it possible to show rotary switch position also ? https://www.dropbox.com/s/0q14x38npgygjqw/aemcd7 link G4plus r32 gtr oil pressure works fixing speed .aemcd7?dl=0

Running a RB26 with ID2000, 91 map is tuned but when multi-fuel was turned on for ethanol. Car ran lean and VE table is maxed out if 30% could be added. only seen about 10% fuel added, so a little confused if there is maybe a over looked step or computer not responding. Side Note : Also want to stream Ethanol content to AEM CD-5 R32 ryan twin pump e85.pclr e85 log.llg

Thanks! ill give that a try

Is there a way to allow the knock threshold to be raised when switching over to a high cam. The 2zz-ge is pretty noise heavy when switching over. sometimes it registers as knock, would i have to mess with window start ? would be nice if there was a High-cam windowing when activated.

Would it be possible to maybe have a CANBUS bluetooth or wifi streamer peripheral, for maybe a link branded app to data log on course. I know the Kiwi is there,Also fetching data logs after each session. but would like to data log the more important things or even all streams at the 1Mb/s rate. in a nutshell a more affordable AIM solo 2 DL but on a phone app with higher data rates.

That was one of my concerns. in the past on a log it showed a 30PSI MGP on a track session but the charger cant go past 10psi. Thanks Adam !

Im having a intermitted problem i've been trying to trace. Where the car leans out at cruising speed or stalls out on decel, also during regular driving acceleration i will have a loss of throttle response as if TPS failed but log's show voltage is fine. i see closed loop adding fuel but hits a max clamp, I've even set it to the limit of 40% and still wants to stall from going lean. but if i do a aggressive pull to WOT everything is fine. As of now the problem exist only on E85 i have yet to check 91 fuel. and recently just started, tune has been running for 3-4 months solid and 5-6 very hot track days So i have checked mechanically Map sensor, battery, alternator, main engine relay, TPS, Can Lambda (no errors on run times), lift pump surge tank pump socks/screen,Injectors(visually Clean but have not put them on cleaner), supercharger bypass. all vacuum lines Fuel pressure checks out . fine as well In the log if you map engine speed with TPS you can see a input of 76% but nothing moves (Logs and Cal file attached) [email protected] LEAN CRUISE_DIES.llg

OK i figured that was another option, This is how it is currently.

I know this is mostly a daily driver request and not a main focus. A A/c Idle target RPM would be nice to have when closed loop is turned on. as of now open loop works fine but letting the ecu do the work would be a super nice add on.
