[rusEfi] VW BUG 1997 #23

[AndreyB]

Please publish your log file also (the file named like MAIN_rfi_report_2016-07-08_22_29.csv from out folder) and a screenshot of console with engine sniffer showing your signal. I want to look at the duration of the signals while cranking to confirm if the duration matches up with cranking RPM, that's about 240rpm usually which is 4 crank revolutions per second which is two camshaft revolutions so 500ms per camshaft cycle so if four vanes each vane would be about 60ms? Let's confirm that with an engine sniffer screen shot.

Hi

[AndreyB]

Can you please post currenttune.msq for 4 tooth configuration as well? Two things do not look right: there are no green lines for engine cycles, and the indexes are going from 0 to 15 and I would expect them to go from 0 to 7 since 2*4=8 and your engine cycle is 4 vanes.

Here is my configuration and how it looks with self_stimulation. Are you always trying new settings on the car or are you trying self_stimulation while disconnected from the car? that could be easier.

Hi
i have only dizy , i suppose to use 4 strk without cam sensor, for me with cam sensor is crank sensor plus cam sensor
ok now rps looks good , disy with 4 vane must use 4 stroke WITH cam sensor
next is try to finish (im a novice) the tune i have 14point7 wide band sensor , i need to build det cans for ignition tune
i in the process of learn, buy, build, for a big hp 400 is target with hi boost, water injection, coil near plug, 2 or 3 injectors per cylinder, return less fuel system, dash app for speed
next step what i need for Frankenstein pcb and steeper iac? , and for 36-1 crank trigger plus cam sensor? for sequential ignition injection( for cam sensor i can cut 3 vanes of disy?) , the bug right now have 3 injectors per cylinder 2 on itb 1 in intake, is much to wish a returnless fuel system ?
best regrds

http://rusefi.com/wiki/index.php?title=Hardware:Stepper_motor has info on stepper

for sequential injection you can start with just cutting one vane out of the dizzy and making it 4-1 setup. At this point we have no experience or data to confirm how many tooth are required for good control - for instance the Yellow Festiva was running great at the race with just 4+1 sensor, your 4-1 would be pretty close.

Let's focus on one change at a time Do you have registered TunerStudio to play with fuel auto tune?

[AldoQ]

Hi
yes i have the registered version of TS
now i have the stepper driver
now what tooth to cut in the dizy ? how many degrees BTD the missing tooth needs
regards

[AndreyB]

as long as you are sure you need it, jusy grind half of one vane off. On the weekend i should be available to help recording your custom signal and setting firmware.

Hi

RusEfi conected to raspberry pi3 with pi desktop and 7 inch touchscreen on my vw bug
i need to make some mount to the screen
i have a drive by wire t body, i in the proces to make the intake to use them

Sweet. I have a PI3, but I don't have an LCD. Can you share the LCD you used, and perhaps the image?

About the drive by wire, that's where you leave the battery charger plugged in such that you get extra HP by not using the alternator to charge the battery, right Keep us posted on your drive by wire efforts. If you need some hardware help, let me know. I might be able to help. As well is your ETB spring close and electric powered open, or other?

[AldoQ]

Hi
the touch scrn is from ebay , try
Raspberry-Pi-7-inch-HDMI-HD-1024-600-Touch-Screen-Module-Kit-With-Mounting


for ETB i have used one from ebay, and is the same as russian have , vw passat , and the motor driver, i need to figure how to instal tps pot or hall chip in the acel pedal
is posible to control 2 ETB at the same time?
regrds

[AndreyB]

rusEfi single ETB is very experimental, never tried on a real engine

[AldoQ]

is time to test, or not??
2 ETB will be very nice, boxer motor , like a pair weber , but modern
for the acel pedal 2 sensors for comparison each one to catch a faliure will be nice

[AndreyB]

Can we start with one TB?

[AldoQ]

sure
only one, mmm, i need to add turbo , a k03 for start



turbo, i have a holset vgt, the acuator control is dead, have a steper motor, is possible to add some electronics to control the turbo wit rusefi???

[kb1gtt]

Stepper has been done for IAC. So rusEFI can physically control a stepper. You can get a A4988 Stepper Motor Driver on e-bay for around $5. I'm not sure about the software. I think it would be a bit of a software development cycle.

Do you need ETB and turbo? Could you do one at a time? I understand the pistons on a turbo engine are shorter for a lower compression ratio, so natural aspirated is less desirable. You might need to do both turbo and ETB. If I recall correctly, the ETB is commonly wide open, or open much more than you would expect, then the turbo is controlled to regulate the intake air. For @ to do the software, he would need to know the algorithm for the turbo and ETB. Do you know what your ETB and turbo signals should be at certain loads and RPM's? So something like 1kRPM, TPS = closed, no load, turbo should be ?? pressure and ETB should be ??% open. Then same at say 2kRPM and 20% TPS, 5kRPM and 100% TPS, 6kRPM and 100% TPS, etc. What should the turbo be doing, and why? That would be required before @ has a chance of developing the software for it. Can you do a log off an OEM setup? Perhaps grab the data with VagCom's VCDS or similar?

[AldoQ]

this combo if for a street drag weekend warrior,
first the ETB, next tubo with pneumatic acutator, next steeper motor for boost control, running in etanol mostly,
i think , rpm vs boost, table for turbo
i dont have any logs or data for the ETB or turbo actuator

[AndreyB]

Time for some fresh images Any updates at all?

[AldoQ]

Hi
let me take the pictures
1 drag bug with turbo, 2 vw bug, one is a 1997 ACD engine with amr 500 blower, 2 is a 2002 with a amr too and i want to add a turbocharger to feed the blower, i frien of mine 1962 karman with turbo, all with rusefi
