Weird stuff happens when you go off the map. Depends on what load level you're at, sometimes wacky fuel trim stuff happens sometimes not. I wouldn't recommend it under any circumstance. The 950 ecu from B204FT has a main fuel map axis that goes to 7013? around 7000 rpm. This should be good enough for most applications.How do I raise the rev limit? Back between pages 100-110 lookforjoe asked the same thing. There's this:
6055 RPM Limiter (rpm fuelcut threshold)
39 is original value this gives appx 6350 off and 6200 back on
38 = 6490
37 = 6640 Do remember that some EZKs have a low RPM
36 = 6780 limit too...just above the 6350 of the LH
35 = 6920
34 = 7070
33 = 7230
32 = 7390
31 = 7550
Is it that easy? I notice that the fuel map ends at 6293 rpm, so what happens when you go off the map? Does it use the last columns values?
Mine to, also has anyone else played with the rev limit that comes in the xdf? I have changed all 4 tables to 3000rpm and the car will quite happily rev out well past 3000rpm. Also in the 208 xdf there is the knock sensitivity table, does this work?
Regarding the rev limiter that turned out to be just hearsay.
The rev limiter is probably just a constant somewhere like in the LH bins.
The rev limit stuff is wrong, as you can see. There's something else that actually controls it that no one has found yet. There is some EZK bin based off of I think a 207 that either doesn't have a rev limit or has something above 7000rpm. I don't know what EZK unit/bin it is, though... It's probably what the chip tuners use as a base for their high rpm stuff.
Your last statement is correct. Earlier XDFs listed the rev limiter as a table with a few supposed values. Changing 0x5EB should work BUT remember to edit all four copies of the EZK bin.Thanks!
Regarding the EZK rev limit, back on page 84:
So this does nothing?
05EB RPM Limiter Hard Cut (177, 148 )
Increasing this constant will increase rpm limit
stock value in bin :
208 = 0x66 (102) = 6500 rpm 7000 = 142
177 = 0x72 (114) = 6650 rpm 7500 = 181
140 = 0x5F (95) = 6410 rpm 8000 = 221
169 = 0x5F (95) = 6410 rpm 8430 = 255
When this is set to max value 0xFF (or 255 as integer) the rpm limit will be raised to appx 8400 rpm.
It will be hard cut of all sparks so best to have LH limiter 1-200 rpm lower
Perhaps they're talking about an earlier xdf that had something else mislabelled.
