Since you already created the pin translation sheet and adapter fittings list, it was just following the instruction and film haha. I’m sure you would have done it better.
Thanks for posting this - had a pretty intense experience with this at the runoffs test day and lucky to have walked away. Does anyone have documentation on the specifics of why the abs unit freaks out and goes rock hard pedal (not ice pedal from overly taxing the system)? Putting together a rules change proposal and want to emphasize that this is a fundamental flaw in the system and not a “I just suck at braking” situation.
My opinion on this is that most ABS equipped on mass production vehicles intended for street use are fundamentally not programmed to compensate sudden & larger speed delta between each wheels during race/threshold situations. Thus it probably won't know how to compensate and does not know when to "back off" when the abnormal values are seen by the wheel speed sensors. The module calculates this as a catastrophic road condition which throws you into ice mode - "rock hard pedal & light pulsations & no braking". Non-track focused OEM ABS is a gamble in threshold situation, even when the car is bone stock (hit or miss dependent on ambient temperature, tire conditions, road surfaces, even rotor/pad conditions). It gets worse as the car becomes more race focused with weight reduction and stiffer spring rates as the contact patches during braking become more sporadic under threshold or yaw/kinked braking situation. This is especially evident when you brake over a bump.
@@gunnkimracing thanks for that! Do you think how bad these are depends on manufacturer? I have a couple BMW’s with no issues at all (Spec E46 and M240iR) with nothing like this. I’ve had ice pedal and weird abs behavior but it was either that I clearly got in over my head or were on junk tires. Is the unit Nissan is using or the programming from them that bad or just straight up addressing these scenarios? The IMSA 370Z’s all had standalone units but I’m sure most other competitors then likely did as well.
Yes it varies depending on the manufacturers. from what I have seen, I believe non-M BMW is fairly reliable, but M3 and M5 variants come with more motorsport oriented programmed MK60 ABS variants. MK60 from M3 swap is very popular because of this @@gaguilarsti
33:26 video shows a part# on the pump, but not sure if this means anything for the actual programmable ABS unit. Maybe the MK60 ABS facebook forum will help guide you.
I had a 16 camaro and had this issue like crazy. I know exactly what you're talking about. So much confusion and nobody understands the issue. Sounds like you get. I'm building a 2020 bmw m340i as my new race car and hoping I don't have the ice mode issue. Glok r8 pads and 265 Falken rt660 with only 20% stiff suspension. Thinking it'll be fine. Do you know if the new m340i has a similar abs system as to what you're installing? Would probably be same as new supra
I'm not sure on the newer bmws, espcially the M340i. I would say the best person to ask is Douglas Wardell at Racing Harness Technology., These MK60 ABS modules in particular used mainly for racecar ABS swaps are mostly sourced from E46 M3 chassis, and some older M5 variants. I would think the newer cars have updated the ABS to be more robust, but can't be quite sure. Nissan clearly did not consider motorsport in mind when they put these ABS system.
Motorsport flashed MK60, Yes you need program service. You cannot just use any MK60. It has to be a specific model that can be programmed . If you source MK60 from a E46 M3 or M3 CSL, you could technically run them as-is as they are still very capable from my understanding.
Solid video man! I was thinking about making a video when I installed mine but was on a time crunch haha.

Great video 👏 well documented

@@gunnkimracing thanks a ton, really appreciate the thoughtful responses.
Great video man, any idea where i can find part numbers for the mk60e1 the internal pressure switch is a big plus

@@gunnkimracing awesome thank you for the contact. Great info in the video and reply.
Who did
you use to reprogram your unit and do you have the part number on the mk60e1 you used?
I believe Andrew Liddell in UK
Does this install require any programming to the MK60 unit?

Where can I buy this racing abs? I'm having the braking issue!
