Have to agree, I’m going to try and get mine as standard looking as I can, may be a tad tricky with the top mount turbo but I’ll give it a go
Coming together really nicely, good looking engine the 225 just the right amount of mechanical bits on show and the cover looks great, will you be fitting the charge pipe decal? Always thought it’s a great piece of graphic design.
i painted the charge pipe black a few years ago when i de-baffled it. i know what you mean about the charge pipe with the decal...but finding a nice one would be the issue.
Looks good in black, purposeful. You can get replacement decals here, probably need to invert the colour of the hand to stand out against the black but I found him very accommodating for custom work. https://oem-carstickers.com/product/bam-caution-sticker/
I've not spent much time on the car over the last few weeks but had some time this week to continue with the wiring. I've made some changes internally to route the wiring. Mainly avoiding the lighting loom coming out behind the brake booster assembely and go internally within the car to the other side, before coming out above the fan air intake and behind the wing. to do this i've made some additional holes in the scuttle, above any water line and avoiding any drains. The image below is on the o/s where i can now route the tach adapter and window wiper loom into the car. Something that i have noticed since the car has come back from the body shop is this. I cant prove it was them but it was like that before it went... guess i'll have to find a replacement somehow.
Theres a mk2 in somerton scrapyard if any use, it's a 5 door, I got load of bits there on my travels.
that strip is actually glued on from the factory, so as long as its just come away rather than split you should be able to glue it back
Bit confused today. The car starts first turn of the key. Runs. Revs. Idles fine. Turn it off and then it won't restart...unplug a couple of injectors and it will start up and you can then plug the injectors back in and it runs normally again. I feel like it is over fueling so probably needs another map or just put the old injectors back in and see how it goes
been googling it a bit and theres lots of threads saying that if there is no coolant in the system, the temp sensor causes issues. I'll fill the system tonight and see if that has an impact. im just confused as its happy as larry to start first time, just hates you turning it off and trying to re-start it
unplug the MAF and starts every time. i did get a load of fault codes logged but forgot to save them haha! muppett. Cleared now so will try again tomorrow as the battery is on charge now.
spent a couple hours out in the garage doing some problem solving and some scanning. i have been having some issues with the car starting fine, but then not wanting to start once it is shut down...i.e. if you were to stall it. i checked all the pipes for leaks, i sprayed a dab of WD40 on the injector seats and saw that this was sucked in slowly, so i will likely have to address this but no other obvious leaks were found. I cleaned the MAF sensor with some alcohol and got some dirt off of it. With the MAf plugged in i get these codes: Charcoal, ABS and Airbag.. no biggie but something i will pick up with Tuning Technics at some point as i asked them to be deactivated when it was mapped.

I also logged group 5 and 22 The logs are showing an average 2.03 g/s at the MAF at an average 857rpm. at 3000rpm i'm getting about 10 g/s without load...just revving. i don't think i can attach speadsheets but heres some of the data: /min ms ms g/s 880 0.7 1.47 2.08 840 0.75 1.54 2.08 880 0.7 1.41 2.01 880 0.7 1.47 2.01 880 0.7 1.41 2.08 840 0.75 1.47 2.08 840 0.7 1.34 1.94 840 0.75 1.47 2.08 880 0.7 1.41 2.08 840 0.75 1.47 2.01 880 0.7 1.54 2.01 840 0.7 1.54 2.01 880 0.75 1.41 2.08 840 0.75 1.47 2.01 840 0.75 1.47 2.01 840 0.75 1.47 2.08 880 0.7 1.47 2.01 880 0.7 1.41 2.08 880 0.7 1.41 2.01 840 0.7 1.47 2.01 840 0.75 1.41 2.01 840 0.75 1.47 2.08 840 0.7 1.41 2.01 1480 0.8 1.41 3.89 1520 0.85 1.6 4.17 1760 0.85 1.73 4.86 2000 0.85 1.79 5.62 2240 0.85 1.73 6.25 2360 0.85 1.73 6.46 2480 0.9 1.86 7.22 2560 0.95 1.86 7.92 2760 0.95 1.92 8.75 2960 0.95 1.92 9.17 3040 0.9 1.86 9.09 2200 0.55 1.09 4.09 1240 0.6 1.66 2.43 800 0.65 1.28 1.67 840 0.7 1.28 1.87 880 0.7 1.34 2.01 840 0.75 1.47 2.01 840 0.7 1.41 1.94 800 0.7 1.41 1.94 840 0.75 1.47 2.08 840 0.75 1.47 2.01 840 0.75 1.41 2.08 880 0.75 1.41 2.08 880 0.75 1.47 2.15 840 0.7 1.47 2.01 880 0.7 1.41 2.01 840 0.7 1.34 1.94 800 0.7 1.41 1.94 840 0.75 1.34 2.01 840 0.75 1.41 2.08 880 0.75 1.47 2.22 840 0.7 1.34 2.01 840 0.75 1.34 2.08 840 0.8 1.47 2.22 880 0.75 1.47 2.15 880 0.8 1.41 2.22 880 0.75 1.41 2.15 880 0.75 1.34 2.15 880 0.75 1.41 2.15 880 0.75 1.41 2.15 880 0.7 1.34 2.01 840 0.7 1.28 1.94 800 0.75 1.47 2.08 880 0.7 1.34 2.01 840 0.75 1.34 2.01 840 0.85 2.3 2.36 3120 1.8 3.39 17.98 4040 0.85 1.73 11.25 3960 0.95 1.73 12.22 2800 0.5 0.96 4.65 1520 0.7 1.79 3.47 1040 0.55 1.02 1.94 800 0.7 1.28 1.87 800 0.8 1.41 2.01 the car seems to behave now. i'm still a bit confused as to what the issue was
i'm going to put together a Power BI Dashboard to present the logging, but i found this list of the groups and what they do..adding here for info: Group 001: Engine speed: RPM Coolant Temperature: Temp in *C Lambda controller: % of correct to the a/f mixture according to O2 reading. %>0 = adding fuel to achieve requested A/F, %<0 removing fuel Group 002: Engine speed: rpm Engine Load: Injection timing: Time the injectors are open to inject in milliseconds Intake Air Mass: grams of air per seconds your MAF is reading Group 003: Engine speed: RPM Intake Air Mass: grams of air per seconds your MAF is reading Throttle Drive angle sensor 1: Position of throttle plate in % Ignition Timing angle: Your current timing Group 004: Engine speed: RPM Voltage supply: Current voltage Coolant Temperature: temp in *C Intake air temperature: Temperature of air getting into your engine Group 005: Engine Speed: RPM Engine load: in % Vehicle Speed: speed at which you are going. (Your cluster might be off, but this is the right speed) Load status: The mode you are in Group 006: Engine Speed: RPM Engine load: in % Intake air temperature: Temperature of air getting into your engine Altitude Correction Factor: Factor to correct mixture with your altitude. (As you get higher, air is getting thinner and less oxygen. The ecu use this factor to correct maps according to altitude) Group 010: Engine Speed: RPM Engine load: in % Throttle Drive angle sensor 1: Position of throttle plate in % Ignition Timing angle: Your current timing Group 011: Engine speed: RPM Coolant Temperature: Temp in *C Temperature: Outside temperature in your engine bay. Ign. Timing: Timing Group 014: Engine speed: RPM Engine load: in % Misfire Counter (total): Total of misfire since you started your car Misfire recognition: Enable or Disable Group 015-016: Misfire count per cylinder Group 022: Engine speed: RPM Engine load: in % Cylinder 1 ignition angle delay: Timing retard for cylinder 1 Cylinder 2 ignition angle delay: Timing retard for cylinder 2 Group 023: Engine speed: RPM Engine load: in % Cylinder 3 ignition angle delay: Timing retard for cylinder 3 Cylinder 4 ignition angle delay: Timing retard for cylinder 4 Group 031: Lambda factor: current Lambda value. (Multiply by 14.7 the value to get to a/f ratio) Lambda factor: current SPECIFIED Lambda value. (Multiply by 14.7 the value to get to a/f ratio) The specified value is the value the ECU is requesting to your engine. Group 032: Lambda (idle) self adaptation: Adapted fuel trim for idle Lambda (Partial) self adaptation: Adapted fuel trim Group 113: Engine speed: RPM Engine load: in % Throttle Drive angle sensor 1: Position of throttle plate in % Atmospheric pressure: Actual atmospheric pressure in mbar Group 114: Engine load (specified) Engine load (spec corrected) Engine load (actual value) Wastegate (N75) Duty Cycle: The duty of your n75 controlling boost Group 115: Engine speed: RPM Engine load: in % Boost pressure (specified): Boost pressure requested by ECU Boost pressure (actual): Actual boost pressure To get PSI, you need to convert mbar. To do so, actual reading * 0.0145 = PSI. But don’t forget to subtract actual atmospheric pressure collected in group 113 Group 118: Engine speed: RPM Intake air temperature: Temperature of air getting into your engine Wastegate (N75) Duty Cycle: The duty of your n75 controlling boost Boost pressure (actual): Actual boost pressure additionally, to get an idea of BHP : to convert MAF readings into approximate BHP figures divide the g/s value by 0.8, or multiply is by 1.25, both give the same result note: looks like you cant go past group 25 on VCDS Lite so i'll use 002, 003 and 004 for now
this felt like a better way to present some of the data, i can also use PowerBI's analytics function to ask questions of the data when i get get some larger volumes. Taking it for a long drive will provide some more realistic g/s and BHP values. peaks and drops can be queried and PowerBI will be smart enought to identify elements like BHP drop due to increased air intake temps or injectors not firing as quick.. something that the novice car guys like myself might not know. Sadly it won't do live logging as the spreadsheet needs to be built and saved by VCDS but if you were able to log it to a database it could update in real time.
Interesting, I’m going to do some logging when I eventually get mine running so I can get a base map on it. Will be keeping an eye on this for sure
Liking the Power BI dashboards, I do a lot with PowerBI at work so its refreshing to see it being used on here!!
I'm certified on Qlik and Tableau but skilling up to get the Power Bi cert, this seems like a good opportunity to have a play with it and keep it interesting
