      @StratifiedAuto I have one of your flash tunes on my car, just installed it today. I was getting decent corrections between 0 and -2.00 (-2.00 being the highest) for most of my test run, then on the last pull, I shifted to 5th at around 75mph, 4500 rpm, and immediately cylinder 4 hit -3.65 This was alarming to me, and I remembered my teachings on the forums to NEVER boost in higher gears. I reset the AP values and did a few more pulls and the high correction did not return, only seeing corrections at a high of -1.65. So its definitely uncommon.


      Also, my AFR sits around 11.10-11.30 in WOT pulls when reading live data, but I must be hitting lower for split seconds because on the min/max values I saw a 10.58 after the pull was over and i was at cruising speed in 6th. (that was not live, that was after the pull, past recorded lowest value). My OAR is at -1 and my Fuel Pressure is around +/- 2k psi. Boost pressure maxes out at 22.7 psi.


      How would you say my car is doing judging by these numbers? I want my engine to last a long time, the car is my daily and I dont want to see her die...shes my baby lol.

      Hi, I recommend contacting us as a reply to your tune email rather than through youtube. Some knock is normal and all vehicles will experience it and your does not sound excessive.

      I think the ecoboost is an awful choice in the Ranger, it's not going to be a long term reliable engine.

      +Scott M you can't get the vehicle as an auto. Even if you could I'm sure it would be programmed to kick down like every other auto in existence. You don't go WOT in an auto equipped vehicle in auto mode and it just lugs along in top gear.

      Hello, hope you can see this comment, i would like to share with you a case of engine failure in a Jaguar XE, which has the same 2.0 ecoboost engine: The owner stopped at a gas station to put some gas, however they mistakenly put diesel on it. This gas station is right before a huge climb, it probably ran full throttle for around 10minutes before bogging down and shutting off. After towing it to the shop, we drained the gas, fill it up with fresh gas, replaced the spark plugs, and it fired, it was very smokey and rough but eventually it ran better. However it would idle in 3 cyl, a misfire code on cyl #3 was set. We did a compression test on that cyl and its dead, 50psi max. Also lots of blowby, even when doing the compression test. Car is a 2016 with 30000kms, so it will go to the dealership. We are looking for the causes of this engine failure, do you think gasoline mixed with diesel can result in pinging and eventual failure?

      Is there any new revisions in the 2.3 liter ecoboost engine because I cracked my cylinder block in #3 cylinder but was replaced with a remanufactured ford engine under warranty in March 2018 from an engine built off the assembly line dated August 31, 2017. My was built 04/16

      The block cracking is another issue unrelated to the head. Basically there's not enough meat in the centre rear of the block, as a result integrity suffers. The 2.3L Mazda MZR DISI turbo block never had this issue, neither did the 2.0 Ecoboost - Why Ford went open deck when designing this engine is anyone's guess.

      no...just the head gasket recall...which is probably why your engine #1 blew

      Hi Alex. What's your take on the HG replacement for the RS? Have there been any failures since the HG replacement?

      Jayco In reply to pr0jectSkyneT

      pr0jectSkyneT at least three cars in the UK are now on their third head gasket (their second non-Mustang one) due to further coolant/oil leaks. All three only had gaskets replaced, so subsequent failures may be down to Ford not checking for warped heads. I still feel the open deck design is a contributing factor though.

      So would you say an increased oil change interval on the 2.0 would help prevent pre-detonation from fuel contamination in the oil? Thanks.

      Certainly fresh and non fuel diluted oil will help in both lubrication and keeping that oil in the crankcase.

      Is this were the 1 step colder plugs help to reduce problems like the ones you showed here?

    • Ryan96se
      Ryan96se In reply to Sarm 1084

      +StratifiedAuto One thing I've noticed is the 2 step colder plugs do seem to hold proper gap for a little while longer than the 1 step colder plugs. I am on my 2nd set of plugs on my FFRP tune. The last set made it around 45K miles before misfiring started. I can always tell when the plug gap starts getting around .032 as the engine starts misfiring under load. Could probably just gap them again but I always replace them with new ones. I have found that setting the gap to .028 on the FFRP tune seems to do well for many miles before excessive gap causes issues again. Got the tune at 8K miles and now have 59K. I worry about carbon on the valves more than piston failure however, I know not to perform hard acceleration at low RPMs. This engine starts to produce torque at such a low RPM range most inexperienced drivers will simply press on the go peddle when they really should gear down to avoid LSPI. That inexperience and/or maybe a shady quality of fuel with advanced timing and higher boost of a tune and you make the possibility more likely.

      They do guard against pre-ignition and Ford prescribed 2 step colder with their FRPP tune (although they do get fouled and are a little too cold in my opinion).

      Funny how after 10 years Ford/Mazda is still having this same issues. I like to say there’s 2 types of Mazdaspeed, Focus ST and Focus RS owners out there, those who have lost a piston and those who will lose a piston lol

      ByteOn Computer Services In reply to ImakeSnowflakesMelt

      The issue is solely a result of LSPI and LSPI affects all GDI engines. If you think Ford/Mazda are having trouble, you don't want to see the issues VAG are having.

      My Mazda 3 MPS has just reached 240,000klms without a single issue, I've never had the engine apart. The reason is I avoid lugging the engine at 2200RPM and I use top quality fully synthetic SN grade oil that I change every 5000klms due to oil dilution. I also have a quality catch can fitted and EGR delete.
