Software revisions for the 1994-95 ECU
| Date | Chip number | Changes |
|---|---|---|
| 2/15/2003 | 318M0215 | 1.8L only, prime shot delay in 1/100 of a second. Z835 controls the time. New air temp algorithm Z865 - manifold heating factor. Z860 - not used at this time, but reserved for cold start below 10*C OEM timing numbers for rows 1,2,3 for better emissions. RPM smoothing for data logs. |
| 2/25/2003 | 218M0225 | Smoothing of air temp compensation |
| 3/22/2003 | 218M0322 | Upper limit of 140 on MASTER FUEL 1.8L modified PRC control, PRC on at all RPM when MAP<90. 1.6L Fan energize temp. Control on pin 1L. |
| 3/26/2003 | 218M0325 | Effect of Z845, boost rise rate doubled |
| 6/9/2003 | 218M0609 | All software now shares the same file format as the Obiwan. |
| 7/9/2003 | 218M0709 | New NA defaults |
| 7/12/2003 | 218M0718 | Full time WBO2 datalogging. |
| 7/30/2003 | 218M0730 | OVERRUN replaces IDLE MAP New NA defaults |
| 8/25/2003 | 218M0820 | CEL knock indicator can now be shut off by adding 16 to Z800. |
| 12/7/2003 | 218M1207 | The transmission neutral switch is ignored if the engine is not running. |
| 12/16/2003 | 218M1216 | Fixes a bug that can cause the idle to hang above 1500RPM for no apparent reason. |
| 1/2/2004 | 218M1302 | |
| 6/12/2004 | 218M1812 | |
| 6/27/2004 | 218M1827 | L4 bug that causes injw to be about 100 points too large when coolant temp is below 50, but it can be avoided by disabling L4 (adding 4 to z800) The L4 disable flag (add 4 to z800) has been added to these chips and users should turn it on during the initial phases of L3 fine tuning. The minimum map zone for L3 autotuning (z860) was never actually implemented for the 1.6b and 1.8a chips, so it is now. |
| 9/2/2004 | 218A2102 | Small bug fixes. |
| 2/22/2005 | 218M2622 | Minor L4 bug fix, and reload labels for SC defaults added. (no actual defaults yet) |
| 3/27/2005 | 216M2727 | Complete revision to all defaults |
| 4/20/2005 | 216M2820 | Further default revision |
| 4-26/2005 | 216M2826 | Default fix. Z820 and Z835 were transposed. |
