Anyone have a KWP2000 Plus that they would like to part with?  I had purchased a kit in 2010, and am missing the KWP2000Plus module itself (I have all the cables of course), I would love to purchase one from someone who doesn't need it anymore.

 

Thanks!

Just following up here so others know.  I ordered an MPPS v13.02 cable from Aliexpress and have used it 5 times now successfully.  Now I'm trying to find an XDF file so I can use TunerPro to copy the remap and shift points from the 365184.mod to my stock image.  Figure that way I can use my ScanGauge and have the better performance and shift characteristics.

I shaved roughly a pound off my clutch flywheel combination and that has made a noticeable difference with the feel of the acceleration even though I am running 2 1/2" larger tires. Which has changed the "happy" place in the RPM band up by 400 rpms.Now starting at 2400 not the 1950 it was at as a stock clutch weight and stock tires.  So add a better tune and maybe it would have normal-ish forward movement characteristics...lol.  Tuning is so far out of my wheelhouse it'll never happen but the idea may be fun...lol.   What has your tuning done to fuel economy?  Just curious, as I have lost some doing what I have done.  Mostly the 2" lift and taller tires I'm sure.

Let us know if you find a proper XDF for the 0.8L cdi.  It seems like I spent months (on and off) looking for an XDF, then trying to convert from OLS to XDF, but ultimately set it aside a while back.  It sure would have been nice to hit the ground running with TunerPro and NefMoto or the like after some previous success with a different car.

My fuel economy has improved a bit, it's been right around 4L/100km for the last couple months, with mixed highway, town and rural road about 50-60km's per day.  I do have wider 195/55R15 rears, but nothing like yours.  I think the 2" lift would be useful on what we call roads here in Nova Scotia .  From my experience, I'm certain a remap would improve yours!

 

I find the stock map works well enough at city speeds.  I've blocked my EGR exhaust feed, and vented my CCV to atmosphere (both helped a lot).  However, with the stock map, I have to shift to 5th on hills on the highway, and still struggles to hold 100km/h.  The best ones I've found so far are 365277.mod and 365184.mod in the cdi.zip pack of remaps that stjimmy uploaded in 2015.  I've been using 365277 since mid-March until a few days ago.  I think I saw someone else here describe it as spicy, and it certainly makes a big difference.  Those same places on the highway, I can easily hold 110km/h in 6th, and actually accelerate up those hills.  Much peppier around town, you can really feel when the boost starts around 2000-2200rpm.  It also has the bonus of auto mode shifts quite a bit better, and doesn't wait until 3000rpm to shift.  The bad: It's almost too peppy, which can make driving around town a bit jerky. It tends to idle a bit rougher then I like, and scangauge-like devices don't work with that remap. 

 

I loaded my stock map again on Saturday to test my new 'scangauge' like device so I can measure boost pressure, fuel economy and a GPS speedometer.  I had forgotten how terrible the car was on the stock map, I couldn't take it.  Monday, I loaded 365184.mod from that same map pack and it's almost perfect.  Better and smoother acceleration without the sudden boost that 365277 has.  I can still accelerate in 6th on the highway on the same hills, and the auto mode shifting is VERY good on that one, shifts almost exactly like I would.   Just back to my boost gauge not working again.  So, if you don't have a device connected to your OBD2 port, I would definitely recommend the 365184.mod!

 

To load them, I have an old Acer 11" netbook with a 64GB SSD that I had Windows XP on.  I only have my flash tools and remaps on it, and I don't connect it to the internet.  Only takes a couple minutes to write a new remap.  It's actually pretty easy after you've done it a few times.

I have found both engine and transmission here, but they are not free.  It seems that there's many places now selling things that used to be shared on various message boards.  Now, if they did create them from scratch then a cost is fine with me.  Anyway, they want 50 euros for engine, and 60 for transmission.  If I don't find anything else, I may send them a message and see if I can negotiate a bundle for a discount.

OldSkullTuning looks like a promising source as a time-saver, especially if they can provide both a comprehensive 450 cdi engine XDF and a comprehensive 450 transmission XDF.  But personally, I don't think anyone should charge for XDF definition files since that's an ongoing group effort for open-source tuning software (e.g., TunerPro), and XDFs are technically ineligible for copyright protection due to being a mere compilation of facts.  I see that I actually have several Smart engine XDF definition files in one of my old Smart folders from 2020, but none were accurate or complete enough to do what I'd wanted in TunerPro for the Bosch EDG15C ECU (0.8L cdi engine), and I'd never even found one for the 6-speed 450 transmission (still considering a manual swap anyway - I saw a 5-speed Toyota trans swap into a 450, but it used the Toy engine too and the fit wasn't pretty).  From memory, I think I got one of the XDF files from the DIY community on the Nefmoto site, another from a batch of dozens that I'd stumbled upon online, and the third one I'd converted from a working OLS def file using an alpha release conversion tool that I'd found on either NefMoto and/or GitHub, but the conversion was either incomplete or imperfect (don't know if it can be touched up or fixed).  I don't remember much else, other than that I was contemplating a full version of WinOLS to simply use the unconverted OLS def file instead of converting to XDF for TunerPro, but my desire to stay open-source kept me from trying that.  See attached (OLS zipped to meet upload file size limit).  Having some experience with TunerPro, my next step was going to be to learn enough about WinOLS to do a manual conversion from OLS to XDF myself, but I never found enough documentation to get the job done.

I did get my hands on this.  I think it's the same OLS file that you have above, but it's been converted complete with the latest version of WinOLS to XDF.  So it may be more complete, although unfortunately it's all in German.  I don't have experience in either app, but learning as I go.  Have a look and see if it's useful.
