Coding Injectors to Fix Rough Start - How to Adjust the Injector Compensation Rate on BMW

Calibrating injectors on a BMW sounds like a big deal and could get very, very expensive if taken to a dealer or even an independent shop. The reason you would want to adjust the injector compensation rate would be after replacing your injectors, replacing the ECU or DME or swapping the engine in my case. Each computer is coded for the injectors on that engine and must be recoded in order to work properly. Normally this job would require ISTA or an Autologic tool which costs in the thousands. Fortunately, there is a cheaper way to calibrate the injectors using the tool above for only $50-60 which is much cheaper than even an hour of shop time. The car I'm performing this service on is a BMW Z4.

I have been chasing a lean code for 3 weeks after engine replacement . This was the entire problem 👍👍👍 exelaint video !!

215 means they are original injectors, they've probably never been changed, so don't get rid of your original ones which are probably updated or replacement ones. the oem ones were prone to leaking, and giving misfires on startup or emitting tons of black smoke on deceleration. I wonder if the new values are based on the flow rates, I just did injectors on an N55 and they were all different.

Thanks this info I didn’t even know I would have to do this it will be very handy once my injectors get here 👌🏾👌🏾

Why does it say hot function is not supported on m vehicle ? I have a bmw 2011 328xi and I need to reprogram the fuel injectors .

[martinvalenzuela]

I pulled my injectors out to change o rings but didn’t label which injector goes back. How can I find the value of each cylinder? I only have the injectors label number.

[RayHoldridge]

Question, I took out the fuel injectors and cleaned them in my 2010 328xi SULEV BMW. But as I was taking the fuel injectors out of the fuel rail, I mixed them up in a pile, not sure what injector was in slot 1, 2, 3, 4, 5 or 6. Does that matter! If so, what do I do about that. Are the fuel injectors marked where each one goes! Or can I just keep them in the car and use this OBD2 scanner and app to calibrate them. Because it's running like crap, hesitation, low idle and high idle and stalls like it's not getting enough fuel. Misfiring a lot and saying injector circuit is open in 3 and 5.Thank you!

Hello. I like so much your video but still dont understand how turn off terminal R. Did many times coding but its not works.Please explain turn off terminal 15 and off. Thank you

One of the best videos i have seen - and simple - right to it - question with the AP2000 app can you run the engine while doing diagnostics or even when programing the injectors. Also how do you tell what version of indexed injector you have - lets say i have an indexed injector of a value of 7 could you put a higher number index injector - sorry i am learning -

[x.trailcwb]

Thanks for the video! Very well made and clear to me. I'm thinking to buy this ap200.

Can this also be used for reprogramming an engine after replacing it with same engine different vin ? Also can I program a
Transmission module ?

[JoseSandoval-icxe]

Hi I own a Kia optima im having same issue just a really rough idle when its been sitting for a while I do remember buying new injectors and shop installing them but I don't know or asked if they reprogrammed them. Could this be reason why my cold start is much rougher and seems to stay there longer??

[traww]

Doesn’t work for me, it just puts the old number back on the log . I’ve tried to change it like 13030277 times still doesn’t work

[antonigaudi]

Hii, do you know where to have a course to learn how to operate fully the obd diagnostic such as autel & otofix to fix a car? Thanks

[walideamine]

Thank you and I want to ask you does it include the all cars for first time please

[adamvet]

I just bought this tool for sprinter injectors coding, but it doesn't show injectors on service menu ? you can only see ( oil reset/ EPB/TEMPS/DEF/Immo Keys / and SAS That all of it on menu .. any idea !! ( I purchased Benz package though that will solve the problem but still missing and thats the latest update as well am using android by the way )

Thanks for your video, I changed the injectors in my audi a3 with the same code number injectors refurbished, do I need to code them to...please

[JeffSmith-dvzb]

Great video. I just had an engine swap done (2012 X5 35i E70 (N55)) w/o injector adjustment.
I found the adjustment numbers written on my 6 injectors. If I put in these numbers into the DME (as per your video) and performance gets worse for some reason, can I switch the numbers back in the DME and engine goes back to operating as it does now?

Detail: May seem like a strange question, but the injectors in the engine now have 23, 000 miles (since 2011), so I wonder if the adjustment numbers have the same meaning. Or if you change the injector numbers in the DME, it resets other calibration of the engine?
Car starts and runs reasonably ok now. But idle seems a little more shaky and some puttering sound compared to before the swap.

[bilna]

Hi, do you know if is it possible to code injectors after replacing them with this device?

[dretookoo]

@simplecarguy i tried it with the same app and plugin and it did not program my new injectors.
