HI,
I have just noticed an issue with GM_VE generated equations. Has anyone else seen this?
Problem description.
ECU VE air values toggle between 0 & 511.99 after pasting tuned equation coeffs from EQ_VE using Ctrl V.
Process followed
1) copy equation data from base tune. Ctrl C
2) gen a new VE table from copied eq's
3) apply corrections to ve table from scan data.
4) generate new eq's from modded VE table
5) paste eq's into VCM editor using CTRL V.
So Far so good the eq data matches in both eg-ve and vcm editor.
If the ECU is started in or std Maf and sd enabled it throws some MAP and flow dtc's then fails to MAF only mode.
In SD only the engine stalls after starting.
A scan of the GM VE air with sd lookups disabled it runs O.K but a scan GM Ve Air pid reports either 0 or 511.99 flows.
6) Open editor and EQ-VE programs.
7) Copy eq's back from editor into EQ_ve.
8) Gen new table from loaded eq's
9) calculated table is filled with duff values which exceed 1,000,000 !!!
If the saved BEQ file from step is reloaded the file a new VE table corresponds to eq's and has good values in it.
Pasting BEQ data via spreadsheet using transpose paste special puts data in however the EQ_VE cannot subsequently read the modded eq's!!.
Curiously there is no obvious difference between the equations copied back in step 7 and the reloaded versionfrom the BEQ file saved in step 4.
Version Info
ECU e38 - OS id 12612381
