EDC15C2 First Gear Limiter

by **wellad** » Tue Sep 24, 2013 9:45 am

Hey guys, just wondering has anybody experience with the first and second gear limiters on a 2.0 HDI 110 with the EDC15C2? I've found the location of the limiters and the rpm/speed ratios on a 90 map, but they're more elusive on the 110.

I haven't gone for a first gear pull with the diag connected, but if I did this and found the limited IQ in first gear would it be OK to search for this in WinOLS?

Thanks :D

Maybe I misunderstood you. But there are no restrictions on transfer. only general restriction IQ.

There does seem to be IQ restrictions based on the ECU's interpreted gear from speed/rpm, at least on PSA models. pro_steve (who I gather knows his stuff on HDI engines) does some fettling with a 2.0 90 map in this thread, which I have been able to replicate on a Xsara HDI 90 we have. However on my own C5 HDI 110, the addresses do not correspond. The first gear limiter can easily be felt on my car so they are present, I've remapped to 70 mg IQ at peak and third gear pulls harder than first :thumbdown:

So give the firmware and addresses and see for yourself.
The fact is that at the Peugeot 307 90 saw several maps of similar IQ, I thought this is for emergency operation.
