gumbiegumbie Posted February 11, 2019 Share Posted February 11, 2019 Got someone willing to help me with programming if I can come up with a vin# to a truck that was a ccrs 427. Mine is a 2001 model and he said the closer the year model the less difficult it would be. I now have a 355/380 and I already have the bigger turbo and my understanding is my current injectors will be fine up to 427 so if I can get the ecu/vcu files squared away I should be good. Thanks in advance for any and all help. Quote Link to comment Share on other sites More sharing options...
Mackpro Posted February 11, 2019 Share Posted February 11, 2019 CH613 vin : 1m1aa18y63w155025. It has a somewhat special engine software/data file in it. We also put CCRS 460P injectors in it . Runs extremely well. 1 1 Quote Link to comment Share on other sites More sharing options...
gumbiegumbie Posted February 11, 2019 Author Share Posted February 11, 2019 Thanks Macpro. Was the somewhat special software in it from the factory? If he pulls that VIN number I won't get the changes you've made only what came in at factory right? What did y'all change up to make it different? I've got the non wastegated 460 Turbo and I was going to try the file without changing injectors and if it doesn't perform to expectations then maybe going ahead with the injectors.

Mackpro Posted February 11, 2019 Share Posted February 11, 2019 It was a factory download. This was back in 2010 when Mack could/would actually do a little tweaking of the files. I saved the actual emails for future use . If you use that vin you will get that actual data file Quote Link to comment Share on other sites More sharing options...
gumbiegumbie Posted February 11, 2019 Author Share Posted February 11, 2019 If I do end up having to go the injector route as well, what do you think about the Rochester stage 2 or 2.5 or something to that effect or just go to the Mack store and buy 460p injectors. Not sure which way would be closer to what would work best and the more you read the more you hear it both ways Quote Link to comment Share on other sites More sharing options...
Mackpro Posted February 12, 2019 Share Posted February 12, 2019 (edited) Looking at the Mack reman booklet . It’s seems there are only 2 injector part numbers for the CCRS engine . Below 460 HP which are 700cc injectors and then the 460 injectors which are 850cc. Sounds to me the 460 injectors are dumping quite abut more fuel. Unsure of anything Rochester but I did speak to them years ago and they knew their stuff. Edited February 12, 2019 by Mackpro Quote Link to comment Share on other sites More sharing options...
gumbiegumbie Posted February 12, 2019 Author Share Posted February 12, 2019 I don't know if it works out exactly like this but Rochester stage two are supposed to be 20% more and 850 is roughly 20% more than 700. I wouldn't want to go above a stage 2 for what I'm doing. I have figured out that go-big-or-go-home usually just sends you home broke down. I guess I would just see who had the best price because the 460 injectors and the stage 2 from rockchester seem to be about the same thing. Thanks again for all the information!
