Upgrade today to remove Google ads and support TLF.

the additional MAP-instrument or *boost gauge* thing shows 3 PSI positive pressure while the Key is in Holgers Hand, and it shows 3 PSI with ignition 'on'. Only thing that differs is that the illumination gets on.. . So as you have installed it I thought as *Doc Mike* you would have tested it!? There is an negative pressure section on the dial, bud it goes not on negative pressure, even if I compare it with the OBD-reading ?? Holger told me that it react slightly on the motorways, bud with that style of working characteristic it is just some *poser style, or pub gathering posing* so pretty much useless in my eyes ! On atmospheric pressure conditions it should read *0* , and go into negative pressure while the throttle is closed on idle. As 1bar overboost is around 15PSI on the dial i would expect 10PSI or so on normal Autobahn sprint runs/gearchanges.. .

Due to the fact, that I have AGAIN the Check Engine Light, I guess I have to buy a OBD II reader myself - I just can

strange thing is that the *rebuild engine* does have such faulty , or fallen off parts :whistle:

By the way, Holger -no, the *freescan*-ALDL type code reader in the LEF-shop is for the 4 pot cars. 'We' (you) would need an ELM-type interface that reads OBD I/II (ISO 9142 in our case) data-protocol. Peter's software is available for free, bud does not work with my *Vehicle-Explorer* TriCan Interface. You need one of the ordinary (mostly illegal copied) Chinese one from the E-bay market. Or Peter will gave you an advice on which product to choose best for his software-tool. Next time (I still have to solve my fuel-gage, and to work on the car of my sister -so i will be here on Satturday...) we can try to change your IAT-sensor with mine. Just to be sure it is not really that hot in your engine :harhar:

In the LEW e-shop they have besides the 4 cylinder scanners also a V8 diagnostic tool, incl. cable, software and interface, for 67 GBP. The diagnostic tool from obd-2.de costs 99 EUR, incl. cables (serial), software and interface.

@ all: Any other suggestions for OBD2-freeware, and interfaces? How about the stuff from Diamex?

Guys and Gals,

As this thread has progressed onto much more involved technical areas of the 350, I'm sure you will understand why it has been moved to the Tech area of the Forum.

It does make for interesting reading, though. biggrin.gif

you can have various software-systems on *obd-2.de /obd-2.com* [on PDA or notebook or handheld application], and also use the free software-creation from *PeterEngland* (member over here). http://www.lotusespritforum.com/forums/index.php?/topic/23500-free-v8-obdii-scan-tool/

Important point/question on all this is: will you get just software or the interfaces with software !? That is the point to mention. For Peter's system you will still need an interface, this for example should be based on an ELM system chip (read his post in the ECM section !)

Kylie does have some more experiences with a *Gendan* handheld from what i know, and some over here use other notebook software (as the vehicle-explorer in my case..)

To assist with finding a local IAT the following information in the service manual may be useful: The sensor has a resistance of 100,000 ohms at minus

40oC and 185 ohms at 1OOoC. The ECU supplies a 5v reference signal.

Mike, thank you for the inscription/labeling of the IAT sensor, and Peter, thank you for the additional info!

Just for info, those who want free scan tool software what runs on the Microsoft PocketPC platform (PDAs and Mobile Phones) try this MicroOBD.

This is the software that I used as the basis for my scan tool.

Regards,

Peter.

Holger,

Any news - did you find/fix the problem yet?

Cheers,

... And I had to realize, that the mount of one screw on the left is cranked, and the screw, that I changed on the right is also the only one that fits, because the mount on this side is also weak. To solve this problem, I would have to take off the whole cam cover and replace the mounts... :thumbdown:

Oh - that is not good..... they are not mounts as such, but using the camshaft caps also for holding the cam covers in place. The front two caps are also used threading in the cam timing tools.... The threads are very easy to strip if overtightened.

If the threads really are gone, then you will need to drill, tap and helicoil them, as the cam caps are a line-bored set specific to each head.

You can have my spare IAT sensor for 20

Mike, as for your last Pm: This is what I'm speaking about -M6 standard should be good !

If Holger has the time, he can bring the new screw to me this evening -or tomorrow. With that i can say what *pitch* it is for the standard cover bold. M 6 x 0,75 looks to be the normal pitch, but I'm not sure what was used on this special application.

Thanks :thumbdown:

If you can confirm the thread size then I can order up the correct inserts while away and have them waiting for me when I return.

Mike, the other hing that i mean is: Item25 -A918E0262F *Locking Plate, turbocharger fixing*

http://www.lotusgarage.com/shop/index.php?l=product_detail&p=6406

those are not there, and that's why he lost at least one of the nuts by now. The nuts are not normal M10 (as far as i can remind..)

:ball: *teacher-mode on* Those plates are good to have, as you can imagine that an nut with normal tightening will loose most of its grip in the treat over time. Especially under those temperature changes. Thats why you would not use plastic-insert lock-nuts :lol: and even the metal type lock-nuts will weaken over time. Or with other words: the pre-crimped nuts will not have their own 'stiffness' for ever. An additional lockplate that fits on the shoulder of the nut and the side of the turbo-casting is an improved way of fixing. Think that's why the engineering department was gone this way too... . The other way is what everybody knows: wire that goes into head head and holds it in position, so that the screw does not turn around.. . *teacher-mode off*

And for the nut: as far as i can remind, the 'pitch' on the big M10 turbo nuts is not the ordinary one.. !'?

That's why I think it is not so easy to get some who fit.

and the funny thing is: the locking-plates are the only stainless parts (apart from the heatshields..) on the engine/exhaust system.

Today I replaced the head lamps (only the H4 thing), and the solution of BerlinWheels works great - they fixed the lamp with four clamps, each of them with one srew. I also took off the IAT sensor to check for a x-ref, but at Bosch, they where unable to determine the right sensor.

Mike, to save yourself the sensor, I
