Hello, Once again I am asking from more experienced users. Car is 996.2 MY 2002 C2 Tiptronic In Durametric there is on actual values: State: Adaptation 2 (rough running) and State: Adaptation 3 (rough running) Can someone give some more information on these values and the acceptable ranges etc. Did searching with google and from forums, but did not find anything on these. I have a rebuilt motor, that I am running in, so I monitor several values and would like to understand these also. BR, Jussi

Thanks. Code worked like charm. Donation done for a good cause. BR, Jussi

Hello, Trying to keep the 996.2 Bose system with Becker radio and the 2nd hand replacement unit came without codes. CR 22 BE 4367 Y5030237 BR, Jussi

Hello All, EDIT: Seems I found nice installation instructions to similar car. Need to have a closer look in it. RCA outputs are driven in to the amp with adapter cable made by moving the line signal cables from 20-pin ISO. I have the same Bose M680 setup in my 996.2 2002 C2 coupe, but I have the CR-2200 ( Becker) Japanese region radio and need to replace the head unit to get the European stations, but would like to keep the rest as original, if possible. I was expecting to see the line level outputs used from the Becker head unit (yellow 6-pin connector section of the 20-pin mini ISO), but was surprised, that only the CD-control section was wired and the speaker output lines seem to be connected to the Bose amplifier. From the picture Loren has loaded, I believe the signal input to the amp is to the connectors B3, B5 etc. Unfortunately this picture does not show the head unit side connections. What is the signal line level I should use to drive the Bose amplifier? I do not have info of the CR-2200 output levels and do not have any info of the Bose amplifier input impedance etc. I found some info of same age Becker head units, that the output level could be 4x15W. Then if the amp input impedance would be 4ohm, the 2V RCA output should work. If the input impedance is 2ohm or 1ohm, maybe the RCA of 3V or Hi-Level (5V) outputs are needed. Any feedback would be helpful. And if there is schematic of the Head unit end of the M680, I would be interested on that also. With google search I found a 996TT Bose schematic, but it is totally different and uses the yellow plug signals from HU. BR, Jussi

Hello 996 collegues, My M96.03 has bore scoring and as the cylinders will be updated, some capacity increase is will also be done. In the 3.8, 3.9 and 4.0 L upgrades from 3.6L have you used the stock injectors or gone for bigger ones and which ones in that case. I think Ecu tune will be needed anyhow. Maybe the first starts can be done with the stock setup and let Ecu to adjust with lambda etc, but for the max power the Ecu optimization is needed. Thus as the max power will increase some, maybe the injectors need to step up a bit. Any idea if the 3.8L injectors will fit the 3.6L engine. The 3.6L seems to be 12ohm, EV-6-E and 3.8 is EV-14. Both seem to be High impedance. I have seen some bigger injectors as 15 to 16ohm. Can the Ecu handle the 16ohm injectos also? BR, Piethein

Hello, My M96.03 2002 3.6L needed to have the heads removed so I am to clean all valvetrain parts as good as possible before assembly. The exhaust hydraulic lifters are the standard INA type and can be easily disassembled for ultrasonic cleaning. My question is for the VC+ intake hydraulic lifters, which are of the concentric type. Can this lifter be disassembled for ultrasonic cleaning, as I do not dare to submerge it to the cleaning fluid in case the cleaning agent can not be rinsed out of the cavities. I have read, that in some cases the lifter has come out in parts, but have not seen any pictures of this lifter disassembled or any info of the disassembly. If there is any info of the possible disassembly / reassembly, any help would be appreciated. BR, Jussi

Thank you. Just got the car, so the instant I saw that code from you, I knew what the hand written number in the option sticker was for... Doh!!! BR, Jussi

2002 996.2 CR-2200 Type 4466 Serial 15000354 Hope, the serial is correct. Others seem to have a letter in front. Thanks!

My bad. Thanks for clearing the link. Modified my post. BR, Jussi

Hello Olli, One manual states 4ms PWM (250Hz) 0-12V. I have seen a valve lift and intake cam advance table only for the turbo. BR, Jussi

Thanks Ahsai, Did not see any spring action mentined in the literature, but we go with that. Any idea if the control valve signal? Is it PWM ? BR, Jussi

Hello All, In some time I have to take the NA 3.6 cam cover open and remove cams, so I have been looking for and reading the 3.6 cam timing instructions. I have done the older VC F1 timing earlier, but the VC actuator is different here and so is the timing procedure. What I have not found info of is the VC + actuator allocation to neutral / park. I found similar allocation info from 3.6 turbo manual, but not from normally aspirated one. My understanding is, that the VC+ valve (3/4 valve) will close all ports when power is shut down, thus it would keep its position, untill the valve is commanded to retard or advance. Thus would it be needed to park / turn the actuator to neutral (0 advance?), before initial tightening to the cam and timing the cam system? Basically the cam allocation. I have tried search, but maybe my tag words are wrong or I have missed something. Car in question is: 2002 996.2 Coupe 3.6L BR, Jussi
