I was wrong! See attached images!

Sorry to dig up an older thread but I'm having abit of trouble dialing this in on my bf fairlane. I've followed the above guide, started at 0.25 in auF0262 and worked up to 0.42 (if I remember correctly) and unfortunately I'm still having it hit the -15 clip then stay there until I peddle it. I'm reluctant to drop the clip to -25 but I've also realised I've gone past the 0 and 0.25 rows on auF2233. Surely I'm missing something.

Extremely late reply but I wanted to be sure the issue was resolved as I've been tricked before 😅 It was intact a faulty powersteering switch. Disconnected it and 75+ hours with 0 issues. Turns out that when I had it unplugged before the abs module wasn't the original as I was chasing the issue ect. So went back to abs module from the fairlane and all sorted!

Have had it unplugged, same issue. Also unplugged noise suppressor same issue. Fitted a replacement abs module today, same issue. Last thing to swap is tcm.

Yeah right. I'll have a look. Being that the steering angle sensor also freezes up with the speed. I'm leaning towards the abs unit.

I actually haven't looked to see if it's there. Psp as in power steering pressure switch? Interesting.. never heard of them causing an issue.. No pattern that I've noticed. It's by far the most unpredictable issue I have had to date.

you can see in attached datalog, the speed is working fine. however failry early on the speed freezes. ive also checked on forscan, all 4 individual wheel speed sensors continue to work. Currently thinking tcm failure or abs module failure. i have changed ; PCM, genuine ford coils, spark plugs. Ive checked all engine bay plugs and cleaned them, i have a spare tcm, not sure if i have an abs module. i have the turbo territory here im stripping but not sure the units are compatible. fairlane speedo dropping out.teclog

Funny you should mention this, I fitted new genuine coils today with a set of bkr7e (it'll se boost very soon) to no avail. I did datalog the issue and noticed even though the speedo drops out the obd2 vehicle speed is stuck at whatever speed the issue occurred. I'll post the data log tomorrow.

it seems the can bus runs through the steering angle sensor. so perhaps thats a faulty unit causing a communication issue. also, yaw sensor is stuck on 0. so ill replace both as a precaution. Its had 4 sets of coils, the new goss set from my territory and a set of ford coils (second hand, known working)

How common is a tcm failure? Trying to diagnose a bf fairlane ghia I recently purchased. Symptoms are : trac light comes up, scan code - steering angle circuit. Speedo drops out, shortly followed by zf sticking in whatever gear it's In. Followed by a shit ton of canbus com errors and invalid data for speed and rpm. Have Changed coils, new battery and checked alternator. Very intermittent issue. Trac light doesn't always come up and seems unrelated to zf issue. Car was well looked after before I purchased it, so I don't think it's a neglected service or anything. Will attach pic of codes. I should add that I've datalogged the individual wheel speed using forscan, they all continue to work after the issue has happened, but the actual speed output stops at whatever speed the issue happens at.

auF2559 - Torque Limit for individual gears ---- usually a issue in second gear are your torque tables stock?

Was just reading this back. This is a btr vehicle yeah?

Is it the pedal vs gear multiplier? (I don't remember actual name unfortunately)

ive tried this afew times with no success. just trying to do it for a laugh. mind if i inbox you about it?

I used it for the W2A pump on our development BA. Worked fine 🙂 will be using it to stage fuel pumps in the next few weeks.

Just adding to this. Seems to be only under 75deg. Haven't stopped it yet unfortunately

That's what I'm thinking!

The car will start fine, let's say twice (hot or cold). Then will not start again until cools down. Rough idle ect ect.

not yet as i only had very limited time today. will in the morning. problem is if its a failing pcm the ba v8 ones are pretty hard to come by i hear.

i completely forgot to post the file. DTCs are plentiful as its a conversion car. RPM signal is steady and perfect. all torque requestors are driver demand as far as i remember. attached is the file as the car arrived HACCKD5 MCsporan drift ute as found.tec 03-10-2022 02-09-41 PM Log cylinder cut.teclog

Hey guys, does anyone have the strategy (03 march boss 260 manual) matching the above teartag? i have a customer car here and the PCM seems to be failing and im unable to read it.

Hey guys, I have a single cam au on the dyno currently with a bf ecu running the show. Currently having issues with cylinder cut stepping in for no apparent reason. I'll post the tune and a data log shortly. Bit of information. Running the car in open loop as it's a drift car and doesn't need fuel economy haha. Have had a search but have no definitive answer.

i have the same unit, i use the dlp. if you need help shoot me an inbox

Was just about to update this! Absolutely right! I found the correct abs calibration and all has been good ever since. So to sum it up. You need the abs calibration to match your strategy/model for it to work happily!

Thank you, will post results incase someone else fights this issue.
