Was playing around with Combi computer and i got it to crash a new way. Starting soon to write Volvo a request that my 24 year old Combi has buggy software and i want bug fixes as i can trigger now temp reading to stuck in max and now i can make Combi crash like windows and make it reboot.

Secondly with Fenix 5.2 i was only once able trigger/command manually via OBDII port to start High speed cooling fan test. Its hard to trigger with button. Need make Arduino or some interface... i guess Attiny85 is enough for that to automate all processes on Fenix 5.2.

: Cam off, everything looks good.

I had the Volvo gods smiling down on me today when I pulled the exhaust cam to remove the broken bolt and to my surprise I twisted the broken end out with my fingers. Now to hit the salvage yards for some bolts because it's Sunday and tomorrow I'm off.

Couldn't some 12.9 grade standard bolts fit for the job too? Maybe earlier one put those original bolts a bit too tight so they now broke. Happily though not with engine running.

There are 5 850s in my local yards and I don't want to play with non factory bolts.

Can you imagine if volvo corporate actually responded to a bug fix request? I could see a software engineer thats been sitting on a bugfix version for 20 years.

I was going to surmise that was going to be the case. I didn't thing it was stuck when you broke it, you just happened to twist that small bolt with enough torque in the the *right* way to shear it. Good thing you didn't have to spend time futzing with that.

Took advantage of some free time to swap out the front struts on my T5. One of the Bilsteins had developed a rattle over small bumps in the road. Installed new Sachs and that took care of the problem.

The main project was converting my wife's GLT to COP.

The engine in the car is a P2 LPT motor (B5244T3) that we swapped in a couple years back. We were keeping it simple at the time, so I "back-dated" it to run the distributor ignition and just didn't use the exVVT solenoid.

Since we already had a DIY flashable M4.4 ECU in the car, it was easy enough for me to mod a fresh ECU (per the instructions from VAST) and wire everything up and flash a new tune. All of the needed mounting locations for the coils, etc were already there, as the engine was originally COP. Dropping in some new Bosch coils and my custom-built harnesses and fired it up. Came to life in the first crank.

Nice! So you have the VVT disconnected... did you do anything with the cam gear, or just set it all normally like you would with any other VVT motor? My cousin is considering dropping a B5244T5 in his ‘99, but this engine is dual VVT and his car has only exhaust. He’s all worried about figuring out the VVT, but I don’t think it needs to be messed with.
I also heard about potential power issues or lack of torque with the VVT disconnected. Have you dealt with this at all? I have a hard time believing it does very much, considering the the VVT is mostly for emissions anyway.

That picture with the engine running and the VVT disconnected was the first test to make sure the COP conversion worked. I went back and finished the VVT wiring and hooked it all up.

We've been running this engine on a distributor and no VVT control for almost 3 years now (almost 30K miles). All I did was set the exhaust VVT pulley properly when I replaced the timing belt during the engine swap, and left it alone. Also flashed the first "tune" at that time. Never really messed with it much since and haven't had any issues. (The trans was becoming more problematic, which is why that was finally replaced a couple weeks ago).

Exhaust VVT is primarily for emissions and a wee bit of economy, but limited performance gain, but I wanted to get it working, and it was easy enough with the proper bin from VAST (Working off of the rear O2 sensor circuit), and modding the ECU was easy.

As long as your cousin sets up the VVT pulleys properly during a timing belt installation, and everything is timed properly, he shouldn't have any issues with just leaving the intake solenoid unplugged. I'm not familiar with the ME7 stuff at all, however.

I *think* someone may make block off plates, but I'm not 100% certain. I may makes some up for a couple future builds I have that may, or may not, utilize the VVT. (I have an '04 R motor in my garage to mess with).
