ECM application The system I got for my CJ-7 has a 16144288 ECM. The guy told me this was used for some V8's but the only place that says they were used for V8's is on Jonas Bylands site. When I look up parts for those models they all list a different ECM. I know the chip runs things but I was drawn to the GM EFI for the limp home feature. It is installed on a 5.9 litre and I am concerned how it will run in limp home mode. Your thoughts please. |

The Mask, ie code that it runs is the A0, MY 91-92. If I'm not mistaken, it was for manual trannies only. |

Am I correct then that the limp home program will not be the right one for my 360? What are my options? |
The only thing I know about the 4288 is that is what I select to view my 16136965(caprice V-8) on WinALDL. Given that it's a C3 and hardware wise they are all about the same...I would swap to something more user friendly. I currently swap the 6965 with my 7747 using the same harness. I have the IAT still wired in so i can also pop a 1228746 in. I don't run the 6965 because the software support isn't that avail (other than tunercat). So until I buy that I just stick to my 7747. But I would not think running a 360 on a 4.3 bin would be a good idea. I know the limphome chips are different in the 7747 from 4,3 to v-8. I do run the 7747 on 4cyl's (which the factory never did) using the V-8 limphome chip. Works so far!!! HTH |
The guy that sold me my systen has agreed to solder the limp home chip from a 7747 into my ECM. I have had no problems but the limp home feature is one of the great things about this setup. Thanks for the input. |
I assume you are doing all the tuning yourself? You are looking at modifying a bin file that was designed for the 4.3 and using it on your 5.9. You could probably take most of the parameters and copy them over from a 5.7 bin but in the end you will have a 1 of a kind ecm that if it fails, you can't go to the store and get another. I would think that the $20 it cost for a V8 1227747 would be worth it to have something easy to replace! Just get an ECM from a 350 motor and plug it in. Get your system operational then start working on tweaking it. my .02 |
The kit was bought from Customefis and included the tuning. The reason he stated for using the 1614428 ECM was that it was a better ECM with features that most others do not have. He has modified the calibration to work with my 360. When I mentioned my concerns about the limp home chip, he finally agreed to do as stated above. He is also going to modify a spare ECM for me at a reduced price. I am also trying to get more familar with things so I can fine tune it further myself. I am sure I will need some help with that as I go along. Once again thanks for the input and any further input will be greatly appreciated. One more thought - is the 1227747 a direct replacement? Will it plug into the same harness? |
