RomRaider

Never mind what's below. It worked somehow and I'm currently doing a full read.


Yeah, no, lol... I did have to get a license key, which I did and put it in, and the tool seems to be launching normally (with the green light) but then it seems to be stuck at 0% forever. I waited more than 10min and it didn't change. The OBDII/usb cable is on the same port as INPA, which works fine. I tried moving it to disk C:, then to program. files x86, windows 7 compatibility instead of xp sp3, run as administrator, restart the laptop/ the ignition cycle several times, nothing...
The only thing I'm getting is what's on the pic attached...what a bummer, I was planning on getting things started today and at least pull my rom and start tuning it a bit...

One thing I did notice, is that after a given time, when I run out of patience and close the flasher and try to start the car, it wouldn't start unless I cycle. the ignition off and on again. Scary stuff

I’ve not run into this issue before. So your cable works fine with INPA?

Ok so I'm happy to report that I have successfully made my first full and partial reads!
I'm planning on taking the following small steps at first:

- Disable the DISA at 5940rpm
- Disable the SAP (I thought that already was the case with that flash but I found it showing as "Enable" under configration. The SES is disabled, hence the fact that I wasn't getting any error message I guess...)
- Move the rev limiter to 7000rpm. About that, do I need to move "soft" and "hard" together, or just one of them?
- Disable exhaust flap, to match the reality anyway (unplugged and permanently open)
- About catalyst heating, since I have no cats, shall I modify it accordingly? I don't know how the DME chooses between the regular "ignition retard" and "fuel enrichment" and the "catless tune" ones. I guess there is a switch of configuration related to that?

Any suggestions about "small steps", before I move on to the more "serious" stuff appreciated!

Yes it does work with INPA, but never mind my previous message, it works fine now!

Ok good lol. Just out of curiosity, can you post a pic of your cable when you get time, if you haven’t already done so elsewhere on this forum.

The limiter is only according to what you want. Some like it agressive, some other don't.
Yes you can modify cat heating if you dont have it physically anymore. On ms41 there are tables regarding time after cold start for ingition retard and enrichment. No clue about ms42 though.

Of course. Here's a link to where I got it from:

Fast and efficient service. Since the shipping itself costs more than the cable, I recommend getting all things OBDII related at once lol. I got the 16 to 20 pin adapater as well as a bluetooth adapter for torque pro, all for less than $20 (+shipping).

Thanks. Honestly when driving I don't even notice that there are "two limiters", except maybe by the fact that when you don't release the throttle immediately it might go a bit further before cutting fuel for good, but I'm only thinking about it now that I know there are 2 limiters lol. I find it aggressive enough as is, so I guess I'll just set the soft one at 6950 and the hard one approximately 80RPM later.

About the cat heating the tables are the same yes, but there are 2 sets: one "regular" and one " catless", except I don't know how to tell the DME that I have no cats
But provided I do, shall I just set all values to 0 (even for ignition retard) and call it a day?

That's correct for the limiter.

I would do that for both ignition and fuel yes.

Same cable I have, ended up buying two.

For the cat heating, since you dont have them installed just set them to zeros.

Thanks for your feedbacks. I will flash it next weekend with those mods. I guess that ignition retard table explains why my logs show the ignition being pulled on cold starts for about 30 sec, with a slightly rough idle.

And it makes sense when I think about it. Less IA means the mixture is not burnt away as fast from the combustion chambers, making the temps raise and helping the cats to warm up

Dumb question perhaps: about setting the rev limiter to 7000rpm, I noticed that the fuel tables go up to 6496rpm. I guess the DME somehow scales them up past that point (for instance, the hard/soft limiters are already higher than that), but I thought I'd ask confirmation just in case.

MS41 cant extrapolate only interpolate .
Rescale your tables.

It's an ms42. Does it make a difference?

Alright so I figured MS42 doesn't do "extrapolate" either since I couldn't find it in the "edit" section of the table (unless it does it when actually controlling injection parameters even if it doesn't show on RR) and tried to rescale the tables under excel.

Here is how I proceeded:

- copy and paste the "fuel base" table
- 7000rpm (target rpm) / 6496 (max rpm showing in the table) = 1.08
- multiply all the cells by 1.08 (which doesn't sound quite right because the lower/mid cells shouldn't be impacted by the fact that there are additional cells between 6496 and 7000 rpm but I tried to do it anyway to see the result)
- paste in RR: at this step, for some reason, RR refused to paste my selection. I must be doing something wrong because I couldn't use the "paste" function for other things as well

After that failed, I thought I would just update the last cell (6496rpm/625load) and hit "interpolate", which worked. I ended up with the table attached here (added the original one for comparison purposes). Except it still doesn't sound right for the same reason I mentioned above (all the cells below 6496rpm/625load shouldn't be affected??).

What do you guys think? Long story short, how can I rescale tables properly please?

EDIT: I even tried copying/editing/pasting the whole table, with engine speed and load headers , which seems to make more sense since at least now the rpm reflect the actual scale they'd have, but the "paste" function still doesn't work...
