Car will crank but will not start after the new pcm. After installing the new PCM that came from 2003 Mustang 4.6 (PCM "MPC-14F") to 2001 Mustang 4.6 (PCM "MLC-463A"). We did the PCM configuration and PATS reprogramming, the car will crank but fuel pump not priming and will not start at all...

An update for the P0602 error code that will not allow me to tune the car properly. After doing the electrical wiring, modules, and PCM diagnostic we found the PCM failed and it said possibility causes by damaged PCM. I changed the PCM and the issue gone with no trouble codes. Thanks god. Now...

Got it. Thank you very much for the support.

Hi Decipha, So from what you explain the following should be the correct data right? Fuel Injector Breakpoint: 0.00001001 Fuel Injector Hi Slope:0.0068997 which is (24.839/3600) Fuel Injector Low Slope:0.0068997 which is (24.839/3600) Fuel Injector Minimum Pulse Width: 0.00070 Fuel Inj offset...

It's not there i already checked before i post this thread. No GM injectors value files in SCT Software. I even went through HPTuner sowftware from a friend laptop and enter the file for corvette C5 as they are using those injector size to get the data but couldn't find what i listed from the...

My cousin car.

as of now he have those and later on he will order Ford Racing Injectors. So any help of having those data for now.

As you can see from this pic the titanium inster and i guess the threaded from inside like the second pic which only half threaded. My question, can an insert like this for our spark plugs cause a major issue such as leak because not fully threaded from inside? Sent from my HUAWEI matte 20 pro

After I replaced the IAC and EGR valves I took a datalog and car will die once I run it. I have to hold the pedal gas to keep it running no matter what I do with the tune until it get wormed and then it will be running fine. The car smell too rich and Air Fuel ratio fluctuating like crazy...

We have installed a set of 24lb GM #0280155931 injectors on 04 Mustang GT full bolt ons (LT headers with x-pipe and mufflers, Edelbrock Jr victor Intake manifold, 6061 custom elbow with 75mm BBK Throttle body, underdrive pulleys, 90mm Lightening MAF, 3.55 gear ratio, Aluminum driveshaft) and HP...

01blckcobra, you're right that something doesn't sound right. I repeated the leak down test today for bank 2 head again for Cylinders 5,6,7 & 8 and all of them were reading on the Green spot in the gouge and only reading 13-15 % of leakage which is acceptable but something I did not get it...

More update: After the leak down test, i found a major leak in cylinder #6 and 8 from, the Spark Plugs insterts that the shop installed. Is it possible to be fixed and have no leaks or i just replace the heads? Sent from my HUAWEI matte 20 pro

Here you go an update I did a smoke test from back of the Intake Manifold vacuum line and i found 2 leaks: 1- IAC Valve "massive leak" 2- EGR Valve "little leak" Can both of those valves creat a lean condition? Sent from my HUAWEI matte 20 pro

Sure I will return the tune back without disabling the P0602 and make a smoke test for vacuum leaks and see from there. After that i will make a leak down test and look for leaks. I forget to mention that during the re-build we installed a new spark plug inserts with red Loctite for Cyl# 6 & 8...

Here you go an update: i tried setting displacement and MAF transfer back to what it was setting before the rebuild. Then i gave the maf 8% more and see how it does. Unfortunately no changes at all. The AF will read rich for 3 mins and jump to lean 17-20 and the STFT1 between 0.97-1.04 and...

Hello everybody, I have a tuning issue at idle after engine re-build either it will go either rich or lean. It will not be stable at all. see below mods with the situation issue. Mustang 2v modifications: D.S.S Racing Block oversize 0.040 with 5.0 Stroker kit, Patriot Stage 2 heads, blower...

Thanks for your usual support. PM already sent to you. Sent from my HUAWEI matte 20 pro

For your info, in the tune we dialed the ECU SWPN which is 13 digits. Should we use the ECU Strategy which is 7 digits? for older models usually we used the Strategy code or the code from PCM. Is the new model the same?

Yes Desipha we're using SCT tune and the code we used from the SCT predator (GR3A-14C204-ADC) so, do you think this code causing the issue? Because the tune dialed proporly. Do you think we have to use the code from the PCM which is EPT2? Sent from my HUAWEI matte 20 pro

Yes we have it back to stock and the issue not there. Sent from my HUAWEI matte 20 pro

We flash it back to stock and the issue wasn't there. I think the tune cauaing the issue but not sure which table cause it other than Cold Start spark table. Sent from my HUAWEI matte 20 pro

The car is bone stock with catalytic converter deleted. Afrer the custom tune we faced an idle issue at cold start only. The car will go to 1400 RPM once you start it and then it will rev up and down from 800 rpm to 1200 rpm like it has Cams on it. Any idea what will cause this issue to occur...

I thought i wrote my thread at Engine Tuning. My bad i will delete it and post it there. Thanks Sent from my HUAWEI matte 20 pro
