Thread: ZHP NA Project - More Power

    285 tq? Is that in ft-lbs or Nm?

    Good journey here. I believe a proper tune should net you much more than 5-10whp with your supporting mods. Have you considered an online tuner?

    I was considering these guys here in the States when that time comes:

    Gotta be 285 Nm. Standard 330i numbers were 300 Nm or 228lbft.

    Greetings guys,

    My latest mod that i did on my ZHP is MS45 conversion to MS43 Finally i decided that spending 350$ just for a tune wasn't worth it, providing that i might have needed to retune it in the future and every time it would cost me 350$.

    So the parts i needed for conversion:

    - 2002-2003 E46 325i/330i or E53 X5 3.0 main engine wiring harness
    - 2002-2005 E46 325i/330i or E53 X5 3.0 MS43 Siemens ECU, EWS, Key (all matched together and disassembled from a car)
    - 2001-2005 E46 325i/330i or E53 X5 3.0 intake air temperature sensor (the MS45 manifold is the same but a screw-on dummy plug is removed for this sensor)
    - 2001-2005 E46 325i/330i or E53 X5 3.0 HFM/mass air sensor
    - 2001-2005 pre-cat O2 sensors (I don't install post cat sensors as i am planning on disabling it with a tune)

    So i began by removing ms45 harness, MAF, EWS, ECU, O2 sensors. The one difference i came across was the alternator clip on the harness.
    MS45 engine harness has a bosch plug for alternator which has a round shape, on the other hand the MS43 engine harness has a round plug for valeo alternators. I didn't want to change the alternator so what i did was, i cut off the plug from ms45 harness and paired it with ms43 engine harness (cut the round plug). Here is the tricky part. The ms45 plug has one cable attaching to the plugs whereas the ms43 has two. What i did was i matched the colors "blue" wire, the rest i think it was green i let it hang isolated with tape. The rest was just easy, what i had removed i replaced with ms43 staff. MAF, EWS, ECU, O2 Sensors. One last thing, the harness of ms43 was from an automatic x5, so there were extra cables hanging, i could have cut off but i hid everything in the ecu compartment. Take into consideration that automatic harness doesn't have a separate plug to attach it to your manual transmition so that when you reverse the rear lights come on and the passenger mirror adjust, you have to rewire an aftermarket cable to the ecu. Which i haven't done yet, when i do it i will post how. For the moment the rear reverse lights and mirror adjusting when reversing doesn't work. Also when you install an automatic ms43 ecu, the car thinks it is still automatic and rpms jump during shifting, also the cruise doesn't work you have to reflush with manual tune. After i isntalled everything, the car started with no problems. I went and asked my friend to flash a tune. We installed a manual tune that had retuned VANOS maps, better throttle response, and ignition map + 7000 rpm redline.

    The cruise started working, the rpms started working as they should and it didn't jump when shifted. Only thing left is the reverse light and mirror reverse adjusting. Overall to sum up the pros and cons:

    Pros:

    - The disa started working, as you know ms45.1 new updated ecus have desabled it to prevent the notorious 4k rpm drop in power. Disa started working means that before 3750 rpm the disa is closed thus little air goes into the enigne bay and it is more efficient which results in better torque.
    - The rpm raise after hitting the gas pedal is beast mode compared to "granny" ms45 :D
    - The parts MAF, O2 Sensors, ECU are 2-3 times cheaper if needed in the future
    - I can retune MS43 as every local guy has the proper soft to edit, where ms45 was limited

    Cons:

    For the moment none

    If someony is interested in more details please post here and i will be glad to help.

    Great choice. We did this for my friends E85. Itís just a no brainer. Do you want my pedal map? Itís like a spring booster. If you hold a gear and hold your foot in the same position, your rate of acceleration slowly increases, just enough to notice.

    If youíve driven a E46 328, I made the first 1/3 of the pedal resemble the sensitivity of that car better. When I went from a 328 to 330 I felt the gas pedal was so damn lazy. Let me know. My tune is stock otherwise I can help you disable 02ís and whatnot if needed

    Thank you,

    I have already disabled o2 sensors and the have the pedal response remaped

    ---Update---

    I have connected the manual gearbox to the ECU with a manual cable. I used the MS45 cable and inserted one cable into the ECU harness where the brown cable is located on the blue relay. I inserted into the brown cable behind the harness. As for the ground as you can see from the picture i have wired on the big black ground cable. After i did everything i found out that the blue relay has a ground on it. I don't exactly remember the wire numbers on the relay i think it was #6 and #2 (negative). The rear lights work, also the passenger mirror works when reversing.

    Notice: If you want the passenger mirror change position automatically when reversing you will need to flash the manual tune otherwise it won't work even though you have connected the gearbox cable to the DME

    Long time no posts.
    I post the updates. I was to a local tuner shop, Gelashvili Performace. He tuned my car, it took approximatelly 3.5 hours on mustang dyno to tune it.
    Before the tune i had 231WHP and afterwards i made 240WHP. The important thing is that 231WHP was at 5600RPM and 240WHP is as far as 6900 RPM. For the moment the car is performing unstable, the ignition is self reducing when accelerating, i am planning on swapping BMW F10 Coils for my old 285 000 KM OEM Coils and i will throw the NGK Iridium 1.1MM Gap spark plugs and will tune again with George Gelashvili. I will post the details as soon as i do it.

    **************UPDATE*****************

    I bought the F10 535 Coils, Delphi and NGK BKR6EIX-11. The car feels much responsive.
    I will retune the vehicle around 12-19 August and will post details.
