2018 Challenger 5.7 R/T original tune file needed

[Benjamin Lopez]

Anybody can help with sharing the stock file for 2018 challenger RT 5.7? very appreciated.

We have various problems in the car, starting by -30% LTFTs in all rpms, it knocks (at 3000-4000rpms partial throat), it enriches too often COT enrichment, it shakes sometimes when shifting (torque fluctuations), we get P0172 and P0175 codes ........ the PCM was manipulated by previous owner: its closed with silicon...... We went to Chrysler to reload OEM file into the PCM, we also checked and replaced AIT, MAP, O2 sensors, we made smoke manifold leak test, cleaned injectors, checked spark plugs etc, cams are following the file tables, ... and not solved, so we now suspect its PCM and even if it is not we want to replace by unlocked one and turn it to VE to see if it is tunable.

I found 2017 and 2019 5.7 OEM files around and ours is 2018 and is almost same as 2017 but totally different to 2019, I would appreciate if anyone can send a 2018 file so I can confirm Chrysler did load our right car file. I would expect 2018 is more similar to 2019 than it is to 2017 as it shares PCM PN with 2019 (not with 2017) and both 2019 and 2018 have exhaust valves but 2017 doesn?t... but it is opposite our file is almost identical to 2017 and very different to 2019 and thats why I want to compare to a 2018.

Thanks in advance.

Thanks Sir, appreciated. Yes it matches our file 100% so now I could confirm we are on the right PCM file. I see the one you sent me missing a lot of transmission tables compared to ours here but I suspect that may be because at the time it was downloaded from the car they had an older version of the PCM Editor... but all what your file has, ours is identical.
