Chipwerke throwing CEL and P0068 - MAP/MAF Correlation Sporadic

[kirk5370]

Anyone else getting this code tripping when using their Chipwerke S?

Ontario, running 91/94 mix, 2012 6MT with Chipwerke set at C-1.

Thanks,

That would be a more common one to get since it deals with the MAP sensors. Clear it and see if it ever comes back. You may want to run B1 on the mix but see if it never comes back. I've never had a CEL (except when I tested it once at the highest setting) but I had a softcode for that once. Cleared it.

If you clear it and it comes back, try going to stock and if it comes back again you know you have a different issue like vacuum leak, map or TP sensor issue, etc.

Yeah, I got the same thing once on during normal cruising on the highway (CW Pro 3-1). Though, the car still drove like normal.

Well it's still a relatively new thing for the B8 owners, I have a bunch of friends with BMW 335i's and they're running JB4 (common BMW piggyback) and have had no issues whatsoever. Quick search will show that the CW S is actually laying down better 1/4 mile times than APR Stage 1. Still one of those cases where the bugs need to be worked out as in any new software.

I read most of that long thread a while back. Seems like the piggyback works pretty good with 93 octane and lower elevations-(at least short term, as no one has run this set up for like 5 years yet on our exact cars to see if there are any long term negative results) -if I lived in a place that had those parameters, I might have tried it. If you read people's results careful though, you see more issues with 91 octane, especially when going to areas of higher elevation from time to time--things a typical California car would have to deal with. I went EPL stage 1 instead and have not had even the slightest issue. The other thing for me was these are like $18,000 engines, and all three respected long time Audi tech's I know (who know a lot more about these engines and their operating systems than most posters here) said they would never piggyback tune an engine of this caliber, and were pretty animate about it being a risky endeavor.

I think the drawbacks are you stated, which is possible jerkiness for some people or having to clear an underboost code once a year. This probably applies to DSG folks under some driving conditions or certain settings.


As far as safety, I'll say I am extremely pleased with the logs I have seen. I've had mine for 10K miles now. The A6 guys have had theirs since 2013 so 20K miles plus and as far as I know out of the several hundred of them being used on our cars no one has had any type of mechanical failure at all. I'd agree to always know what your getting into with piggy backs in general as far as logging them as some vehicle ECUs dont have the intelligence ours do but the Simos on our cars runs them really really well. I saw a log of a JB1 on an S3 and it was running lean and had high EGTs (it was all cranked up) but on our cars you can go to max Chipwerke settings and even add a pulley and our fuel trims won't let us run lean. For those folks who were running really bad winter 91 octane the car continued to pull timing and bleed boost indicating all safeties were working perfectly. So as far as safety on the S4, it seems to be a non issue at all.
