Martijns 854 T-5R - Naar zijn laatste rustplaats

[t5joost]

Waarom heb je het 850 inlaat gebruikt en het inlaat van schutten?

[Johann]

Hij loopt

geweldig dat de t5r de weg weer op gaat! veel succes met het afmaken van de auto! ga dit zeker weer volgen

[Rense850T5]

Martijn heeft geen inlaat van schutten en deze is opgeboord en zit een 960 gasklep op.

Zojuist een nieuwe APK behaald. Kwam er prima doorheen, ook geen emissie problemen. Toch blij dat ik die 200 cell racecat erin heb laten zetten vorig jaar
Ben bij een echte rotterdamse garage geweest waar de eigenaar van 70 jaar de tent nog runt. APK werd met 4 man uitgevoerd, waren binnen 10 minuten klaar..heren waren precies op elkaar afgesteld.

@Joost: eerst zo aan de slag, spruitstuk van Sebas zal nog volgen! Jij hem er al op zitten?

Weer lekker bezig Martijn. Ziet er goed uit!

Nee nog niet blok staat nog voor de auto.
Oude blok zit er ook nog in. Nokkenas deksel er afgehaald, kleppen moeten nog gesteld worden op de nieuwe assen. En dan kan ik gaan opbouwen.

Update, even copy/paste vanaf VolvoSpeed:

   So, time for a big update! A lot of work has gone into the car in the past weeks. What has been done:


   - Installation of COP module

   -Installation of a 16 channel Logbox (created by Maarten)

   -First experiences with ME4.4 tuning via TunerPro on the Autobahn in Germany

   -First data analysis out of this

   -Mounting of several sensors for further data logging

   -Experiences with limits of RON95 and cam timing


   COP module to upgrade ignition

   When I bought my B5244T5 2006 engine, I purchased the wire harnass for the COP's with it. Mainly with help of Maarten the wire harnass was adapted and has been installed. What is amazing is that with the lastest techniques you dont need any extra add-on modules for COP steering.It took some further tweaking in the BIN, but soon the car was running on COP's






   Installation of a 16 channel Logbox (created by Maarten)

   So in order to be able to data log I purchased a 16 channel logbox from Maarten. With this, you can just add 16 channels to the .adx file of Tunerpro. 14 channels are +5v channels and 2 channels are for Thermocouples. I will connect the following sensors:

   - EGT sensor via K-Type thermocouple
   - Oil temp sensor via K-Type thermocouple
   - Intake Air Temperature / before turbo
   - Intake Air Temperature / after turbo, before intercooler
   - Intake Air Temperature / after turbo, after intercooler
   - Crankcase pressure sensor via MAP in the ventbox
   - Boost via MAP in the manifold
   - Exhaust back pressure via MAP just on the lip of the exhaust housing of the turbo where it meets the exh. manifold. I use a 0.6mm welding tip just before the sensor to smooth the signal.

   The logbox is very compact and fits nicely next to the ECU.











   Covered all new extra wires in nylon protection snakes



   And clean install in the end:




   First experiences with ME4.4 tuning via TunerPro on the Autobahn in Germany

   Then, I paid a visit to German850R who lives not so far from the Dutch boarder in Germany. We spent a full day on getting familiar with TunerPro. A lot of reading and some tips via other forum members over Whatsapp helped a lot. I decided to run on RON95 fuel, as this is easily available throughout whole Europe. Next up would be 98 in NL, and in some areas you can get 100 or 102 octane fuel. I knew using 95 would cost me some power, but I wanted to start off safe first.

   First, we calibrated the injectors so that the fuel trims would be as close to 0 as possible. This took us twice, as the first time the MAF table wasnt scaled up to my Volvo S90 MAF. After re-scaling the MAF and increasing the load to 16, we could start working a bit on the map. At these moments is very nice to work together with someone as one just drives and keeps his eyes on the road, whilst the other one changes the values in the maps in TP. As I am driving with the wideband mod, it didn't take very long to find the right fuelling table. Just needed to add some fuel in the mid range around 2500 rpm, as in higher gears the GTX starts to make boost then (0.5 bar) and I would like to be already at mid to low 13 AFR's around there. With the WOT AFR set at around 11.9 (requested) we saw around 11.7 to 12.0 AFR, which was fine for this moment of time.

   Adding some boost to the game, I started out easy with 0.6 bar the car felt more responsive. Added some timing mid-range and had a shar eye out for knock. After some pulls decided to up the boost towards 1.10 bar (17 psi). Car ran very nicely on this, and because it's the autobahn we played around with a BMW 435i with AC Schnitzer goodies on it (expect it have 340 bhp and 450nm). To review some logs we decided to pull over, get a drink and sandwich and check out what the car was doing.




   I wanted to try more boost, so set the EBC (yes, in future i will use the TCV and M44) to 1.3 bar (20 psi). Somehow the car stopped to build boost after a pull.. so we pulled over and it took a while until I noticed that the wastegate was jammed. Too bad, car was bloody hot and didnt want to touch that thing. The issue was later resolved by changing the position of the internal wastegate:





   Continuing at 1.1 bar I tried to get a bit more timing out of the map. We tried to let it run a bit richer at peak torque which I expected to be around 4700 rpm. This is the area where the engine would slightly pull timing on longer (=hotter air) runs. Not a lot, just 2.25 degrees (sum of all cylinders) so like 0,5 degree per cylinder. It became clear that a slight richer AFR (from 11.8 to 11.4) was not really allowing a lot of more timing. I ended up with the following map for that day. Ignition advance around 6.5 on peak torque and hitting 10.75 load with my Bosch 660 cc injectors.With this baseline the car runs very nice and smooth. Under light boost or even off boost it is very responsive.

   Yet the timing i can run is quite low, I think that there are some things influencing my timing.

   - Fuel quality (will get premium octance 98 next time)
   - Cam settings: I expect the B5244S N/A non vvt cam to have a longer duration and therefore more overlap.

   I will continue in the upcoming weeks. Here are some pics of my maps and a log:





   And by the way, later that week I did a pull at night (only 10 celcius, it was cold) and could add 2 extra degrees of timing already:

Wow, mooi om te lezen en te zien. Keep us posted

[razorx]

Lekker bezig!

[Martijn_B]

Kleine update, er zijn wat spulletjes binnen:

4" BMW MAF behuizing met nieuwe silicone slangen (zwart deze keer...ik wordt oud en wil van blauw af)
ENEM Y21 nokkenassen met hogere lift

Ook gaat de EBC er uit en ga ik over op gewone TCV aansturing. Zit nu nog een weekje in Zuid Amerika, maar vanaf volgende week aan de slag met de upgrades samen met Rense.

Goed bezig martijn! Top hoe je elke keer weer weet te verbeteren en het geduld hebt voor alle motor projecten so far. Heel interessant om te lezen, leer er veel van.

[Martijn_B]

Nieuwe ENEM nokkenassen met 9.8mm lift.




Nieuwe timing map op eur 98 en 1.1 bar

[Jurijn R]

Yo Martijn, mooi dat je nog wat post hier. Zie wel vaker wat op Volvospeed dacht ik 
Nou lees ik dat je 1.1 bar doet maar zie toch al pieken van 1.25, waar ie toch net wat zakt terug. Op 5640 rpm doet ie geen 1 bar meer... 
Vermogen komt er aardig vroeg in +- 3900 rpm ( voor een GT), misschien net wat later nog en dan een piek van 1.2-1.3 bar aanhouden tot eind van de toeren?
