Fuel Throttle Enrich (VE) Type 4

[Matt]

Sorry I've been stuck on another issue over the last week (trying to locate the TP/RPM parameters for closed loop still, for non-FP ECUs) so this has been trying up my time

[Matt]

I've been having a good look through all ECU models with the VE map code and making comparisons.

The ECU code will always copy RPM scale and then the TP/TPS scale to Y and X pointer before accessing the interpolation map. Some of these were correct (NEO) but others were inverted in the address file

It explains why changing the scales were not making sense

Ones needing changing were:
B14 SR20DE (yours), P10/B13 SR20DE (1994-95), Z32/J30 VG30DE (1994-95),Q45 VH45DE (1994-95), U13/S14 KA24DE, N15 GA16DE

There will be an update soon with new address files. I've just got to test the changes against VE map.

Okay updated software has been put up 1.2.95 with VE tested on this ECU and also K11 with the injection time responding right on the trace cursor

This is awesome Matt your the man, i'll def play with this and report back with some logs and findings, this should help out a lot!

Yeah all the RPM scales are x50 where previously I had the affected ones x25 which was not correct, so those are fixed up. NEO ECUs still have 2 x ATPS indexing, but these other ECUs are just straight ATPS indexing
