  4. Can’t connect to Ecu

    in G4+

    Posted

    Hi all, like the title says I cannot connect to my ecu. Its not a new laptop I’m not new to the Ecu, I have connected many times prior to this and now all of the sudden doesn’t want to. I’ve tried uninstalling and reinstalling and so far no luck. Checked the usb cable and nothing. I haven’t tried a new cable but i don’t think is the cable since it shows on the device manager tab. It’s more like the program is not recognizing the Ecu because the laptop is or at least that’s why I think

    Hi guys just wondering I know it reads a bit higher than a normal 5 bar but when I looked into my friend’s tune he had a link 5 bar option selected for an aem 5.2 bar map sensor. Is this ok? Or does he needs to set up a cal table?

    Your over-run fuel cut is turning on and off.  Set that much higher like 2000-2300RPM or turn it off all together.  

    And increase your idle base position by about 20 so that closed loop is not having to correct so much.

     20 steps? in the whole table?

    Your idle valve position looks fine in your log.  The red/orange colours on run times are user configurable warnings, if you havent set them up to something suitable then you can ignore them.  

    I dont really see much of a problem in your log when AC turns on it seems fairly stable?  Where in the log is this "AC problem"?

    Also, your injector PW is still commanding 0.3ms so you havent set the 0.45 minimum PW that I told you to do a couple of days ago.

    Why are you running such large injectors and high pressure for a petrol based fuel?  2500cc is enough fuel for about 1800HP @ 85%DC?  Seems a bit optimistic if you want it to idle nice and AC to work as well...

     

     

    The PW was my mistake I’ll fix that. The reason for the injectors and the high pressure is because yes right now the car is running 93oct but for racing it will be Ignite 114 which is ethanol on steroids the blending is with race fuel not regular gas and it demands a lot of fuel.  I still need to wire the ethanol sensor so I haven’t tuned yet for that gas but it will be. Now that injector dynamics released the new 2600cc injectors I might get those and lower the fuel pressure to 43.5psi base, but as of right now I might not even make it pass 40psi with that fuel. I’m looking at maybe 900-1000hp if the injectors allow me. Here’s a link for the ignite http://www.igniteracingfuel.com/114.html 

     Now for the ac when I’m coming to a stop the idle starts bouncing from 1000 to 2100ish up and down and I have to turn the ac off so it stops oscillating. Let me take a look and tell you the exact time it happens

    So now the problem is with the AC on. I've done the proper procedure using link help file. But as Adam told me I think the iacv is operating outside of its range. When I see the runtime values the idle step turns orange or red so I'm assuming that means out of range. So when the AC is on it's chasing the target idle. Keep in mind I'm no tuner at all and I just took the HP Academy classes so I know very little. I'm gonna attach my last log and map. current map.pclr

    here is the log since I can't upload it because of the size

    Your injector actual pulsewidth is only 1.2ms in that area, most injectors will be very non-linear with such a short PW.  You cant expect an engine with 2500cc injectors on petrol to cruise lean like a stock car.  You will likely need to increase the min effective PW setting to about 0.45ms and target a richer lambda during idle and cruise conditions (or lower fuel pressure) to prevent the injector operating in this region.

    Are they actually ID2000's or some other brand?  Many other suppliers that sell the 2000CC CNG injector dont dynamically match them at multiple pulse widths like ID do so it could be even worse that shown below with some other brands.

    Notice the pink lines I have drawn on this graph.  This shows the injector flows 40% less fuel at 1.12ms PW (15uL) than it does at 1.25ms (25uL) so it only takes a 0.1ms change in PW to turn all to custard.

    Yeah Adam they are ID2000cc and I used the table for linkecu that they provide in their website this info https://s3.amazonaws.com/cdn.freshdesk.com/data/helpdesk/attachments/production/4038524102/original/ID2000 - Link G4 Thunder Characterization Tables - 4 Bar.xls?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=AKIAJ2JSYZ7O3I4JO6DA%2F20191119%2Fus-east-1%2Fs3%2Faws4_request&X-Amz-Date=20191119T114836Z&X-Amz-Expires=300&X-Amz-Signature=a8d5de60a68717def2b3c0221acf5a471759e541b5e7e5fb0fc59b38fd534562&X-Amz-SignedHeaders=Host&response-content-type=application%2Fvnd.ms-excel

     

    so target a like a .95 lambda? And up the min PS  +.45? Ok no problem I’ll try that. Thanks Adam

    your fans kicked on right before the voltage dip.  

    My car makes a similar hiccup if the fans kick at low rpm causing a voltage drop.

    Not sure why you have 2 DI's set as AC request.  But they are opposing so its always trying to run the AC?  Compressor clutch is always engaged, or at least thats what the log shows.  Might have something to do with why its also running so cold and the fans are cycling.

    The ac request is like that per instructions as far I’m concerned though. If not the AC won’t work.

    Regarding the ignition table, the cells from 0 kpa and lower, are way off... I would copy the base map table and fine tune from there. (0 kpa to -20 kpa @ 4000 rpm to 5000rpm look decent)

    No yeah I’m just trying to tune the idle first. I’m going to order a set of Nerdtuning knock detection headset. And tune from there

    I gave you those values to use

     

    Ahhh ok thanks I’ll try them today and let you know.

    Its not much of a log but it doesnt look to far off working now.

    A couple of suggestions:

    In the idle control settings, chjange the AP/TP lockout to 1%.  

    Fix the ignition table and the idle ignition table.  Remski's idle ign table above is what I would expect to typically see.  

    For the ignition table I would expect to see numbers around 10deg in the area I have marked pink, and 30-40deg in the area I have marked green (with some blend in between these areas and the surounding cells).

    I’ll do that Adamw, the reason those values are all messed up is I tried to idle the car with the idle control off and with 10 degrees of timing the car would idle at almost 2k don’t know why though

    Here you go Adam, log with overrun off and close loop lambda off.

    Assuming your base "idle igntion" is 10deg...

    Your Idle ignition table seems wrong. 

    It uses actual degrees and does not substract from main ignition table.

    that doesn't seem like my idle ign table.
