those macks with square connector are a bitch. they can't delete egr on it, and it is a pain in the ass to have a good delete. unlike the ones with round diagnostic pin (both 6 and 9 pin), i have entire fleet of those deleted and it is the best thing i ever done.

Dang I just saw this. I am not very often on forums sorry. I get here from time to time, and inform people about all issues I had and sovled them. Any how I had a problem with oil leaking into ECM and shorting it. So do the preventive checks. I didnt cut any filters to look for metal but you can do that, if you find metal - you are toast (engine rebuild is about to happen).
-
I gave up on struggle with emissions. Tried baking filters, doing preventive maintain of systems - nothing helped. Check these guys out they saved my business can't thank them enough https://truckecmtunes.com I am talking about trucks not about machines
-
They do know to be a pain in the butt to remove. Sometimes they got stuck real bad. I fixed my issues with deleting them. I recommend https://truckecmtunes.com

Mp8 sudden momentary loss of boost pressure
mp8_macky replied to Rockwell's topic in Engine and Transmission
I recommend that you check EGR valve that can also be an issue, if it is sticking. Do you check for codes? Try cleaning the boost pressure sensor (i doubt that it will help, but you can try). -
yes i did block off egr. it must be blocked on intake side too the tuner requested that

we had all of sort of issues like this until we deleted it. will repeat once again we used this guy https://truckecmtunes.com it saved our company!

The mentioned problems of cracking exhaust is because of excessive heating. The issues could be that they didn't drill the DPF DOC SCR filter, or the filter has collapsed - all this would result with an exhaust restrictions. You are supposed to put a 5inch hole in the center of filter, and my tuner recommends fitting a pipe in that hole(to fit tight) so the filter does not collapse. I've done more than 500.000 miles with my deleted MP8 - and never had a problem like that! The tuner I use is https://truckecmtunes.com

Mp8 goes from 415 to 485. 500bhp is on 2010 and up.

If you are deleting it, I recommend my guy https://truckecmtunes.com

Go to parameter programming, there select mid128 and you will find boxes for programming the injector codes. The thing is that you need to have PTT that has those things unlocked (level as high as dealers). My tuner saves the injector codes before programming, and make sure to put them back. I learned all this from him, and I done quite a few Volvo/Macks and never had issues.
-
On my Macks fan comes on 210. You can change when the fan kicks in parameter programming using ptt program.
-
I did quite a few of those, and never had a single issue. The guy that does them for me, states in his instructions that you should verify that engine fan is working after the delete. Also I remember that he told me that there is a parameter on which temp. fan kicks in, you can change that in ECM. Check out https://truckecmtunes.com

I am not sure if they do those macks, but they did magic with my MPs. Take a look at https://truckecmtunes.com
-
if you are replacing injector make sure to program new injector trim codes/files. you will need ptt program to do that. also, injector cups are common issue on those
-
Yes that is true, but still I had to do it and I don't regret it.

considering the fact that i almost got bankrupt, i just have to share the following with you, it saved me. no matter how much you invest in repairs - it won't run well. https://truckecmtunes.com/

VMAC Interface tool/software
mp8_macky replied to thomastractorsvc's topic in Engine and Transmission
i think you can use it on VMAC1 it has that option, but i didn't try -
maybe try using a program such as Norgeon JPRO - that is not bad at all. i had good luck with it. i do thing that you can reset the learned data in PTT under Engine section - and something called Aftertreatment data... (can't recall). best option is deleting it, this saved my ass big time https://truckecmtunes.com/

Anyone doing full deletes on MP8s yet??
mp8_macky replied to bulldogfarmer's topic in Engine and Transmission
Problem with the guys I use is the fact that they insist that you have diagnostic adapter and some repair experience, but I can tell you for sure that they are the best money can buy. Reason I am saying that is because I re did couple of bad delete tunings done somehwer else, and had nothing but good luck with them. Also they can do the OBD Macks and Volvos. Thumbs up for https://truckecmtunes.com/ -
