2014 Ford Fiesta ST 1.6 Ecoboost suffered LSPI at Cylinder #1

83000km Cylinder #1

LSPIs can happen from Lugging your engine. Which it sounds like you're doing. Lugging is when you floor it at a low RPM, it overworks your engine. You should always be at least at 2500rpms or higher before you floor it in any gear. It's especially bad for turbo'd cars.

no it does not only with a shit tune with a standard car never the electronic throttle does not allow 100 percent open below 3500 rpm a shit tune does

[@mikegaming3826]

@@JM-vu1bk well this is about a fiesta not a toyo or alything the electronic throttle doesnt allow 100% till 4k rpm?😂😂get it from me, im a tuner

[@mikegaming3826]

@@JM-vu1bk no but a shit tune allows 100% throttle at 1500rpm thats the main cause of lspi it can accure always but thats really the main one my tunes allow 85% throttle at 3.5 and 100% throttle at 4k than lspi can accure so much less than a tuner that allows it from 1.5k why you think dord allows it on a stock engine at 3.5k? To make sure lspi doesnt accure always…

@@JM-vu1bk lspi cant be elimminated in most cases but mapping the car so the power comes on lower in the rmp range is not gonna help at all😂

[@elianderson3956]

Bruh what gear are you flooring it in? I can clearly hear you bogging the engine😭

[@wilsonwong8560]

5th gear at around 2000rpm

[@elianderson3956]

@@wilsonwong8560 yah that’s ur problem don’t floor it in 5-6 unless ur already flying and don’t floor it unless ur above at least 2500 rpms

[@wilsonwong8560]

U know now

[@evanshaw4371]

@@elianderson3956 shit even 2,500 I’ll still get negative ignition corrections like -6. Around 2,800rpms in any gear is when you should floor it.

[@elianderson3956]

@@evanshaw4371 they do dyno testing and data logs at 2500 Rpms in 3rd and if ur getting that big of negative corr on wot at 2500 then you have a problem!!! If ur running a ots tune drop it ASAP and I’d recommend looking into that bc that’s way to high

[@IZ8MWG]

Modern gasoline engines are absolutely piece of clunkers! Too high specific power (over 100HP per liter) on small turbocharged and direct gasoline injection with exhaust gas recirculation and 0W20 water-like oil that fills combustion chamber full of absolutely shit carbon buildup that increase compression ratio and create also hotspots igniting gasoline for compression like in a diesel.

[@chrisedgington9633]

Only Amsoil and 93 octane shell for my 17 turbo cruze

[@wilson1149]

Downshift manually before you floor it.

[@MateQ2k13]

how much you paid for repair this engine?

[@mixalisomonoia1989]

what modifications????

[@aquactrl1484]

Using a higher quality of oil like amsoil prevents lspi.

[@ceebee2881]

Did you re-map the ECU? or used any tuner?

[@fluffymat1]

Do release this is the mappers fault for letting the car going full throttle at low rpm, a good mapper won’t let the happen they would give 60/70 at 2500 rpm.

[@wilsonwong8560]

Mapping may affect but many of stock ecoboost engines suffered LSPI. look at Eocboost in Taiwan, Disaster !

[@fordyford]

This is not "the mappers fault". Flooring it in 5th gear from 2000rpm is unfortunately the drivers fault. I think he has since realised the issue.

[@honestrunescaper]

This isn’t serious. I think you are overreacting

[@elianderson3956]

🤣🤣ur joking right?

[@outdat3d-04zx10r-ha]

My guy his engine is pooring white smoke and knocking like no ST I've ever heard and I've owned 4 and driven hundreds lol...just don't go full boost at low rpm and this doesn't happen

[@LJI96x]

@@outdat3d-04zx10r-ha I don’t even know how he’s managed this, the 1.6 EBs were and still are properly bullet proof so he must’ve got really unlucky with lugging the engine? Usually the 2.0 Focus ST lumps are plagued by LSPi

[@outdat3d-04zx10r-ha]

@@LJI96x yea I have the 2.0 ST and it has 110k miles and runs like the day you would pick one up on the lot...I try to stay heavy on maintenance and will not go above 7psi lower than 3k rpm...there is so many people that just floor these cars in 6th gear at 50 mph and its wayyy to much lol...I just wish more people would care about their possessions and do the research on how to maintain and drive it correctly

[@outdat3d-04zx10r-ha]

@@LJI96x it's also possible it wasn't lspi I guess...maybe the turbo went out or something with coolant... definitely weird on this motor ....had to be abused/faulty part/or poorly maintained
