James 2 Report post Posted April 16, 2017 Purchased used GT86 and found out next day that previous owner had had vehicle remapped using Fensport Ecutek software. It was set on Map 2 and I have since switched it to Map 4 (non-super unleaded option). 1) I assume that having used half tank of standard unleaded petrol whilst in Map 2 setting will not have caused damage/ created issues?! 2) I have no wish to bear cost of super unleaded (sorry). Am I better of just keeping in Map 4, or go back to standard "factory setting" Map (and if the latter, how is this achieved?) 3) I presume previous owner will have voided 5 year Toyota warranty by remapping?

Lauren 2259 Report post Posted April 16, 2017 Hi James, 1) I think you'll be fine, though it is worth noting that even if you didn't have a remap it is recommended to run on 98 RON fuel, so super unleaded and the best fuel is Shell V-Power Nitro. 2) You can get the maps removed and simply go back to a stock tune. Obviously this will cost you. It will run okay on regular unleaded (I admit, I've never tried it myself), but obviously with a slight loss in performance. 3) It's not crystal clear, but if you had a problem with the engine it could void the warranty but wouldn't affect anything else. I guess you could remove the Ecutek software and keep your warranty that way. It is unlikely that they would be able to tell. Share this post Link to post Share on other sites
Gringosteve 213 Report post Posted April 16, 2017 I would really not recommend running on standard fuel even on the standard car. It tends to run lumpy Sent from my iPhone using Tapatalk Share this post Link to post Share on other sites
CHOSENMAN007 81 Report post Posted April 16, 2017 All dealers would recommend 98 octane or above in most cases. And I'm pretty sure they sell them fueled as such. Share this post Link to post Share on other sites
jevvy 40 Report post Posted April 16, 2017 Close to me is 97 and 99 Ron fuel the shell is in town 20 mins away so I only go when nearby what's better in the absence of shell Share this post Link to post Share on other sites
James 2 Report post Posted April 16, 2017 Thanks. With cars I have owned in the past I've only ever used the standard unleaded, on the basis that the super-unleaded was more costly. It never occurred to me to buy the more expensive stuff. If you are supposed to used super unleaded even without the remap, there is probably little point in going back to stock settings (concerns about the warranty aside). 1 jevvy reacted to this Share this post Link to post Share on other sites

Supposedly you get better mpg from the best fuel for your car anyway that makes up for the cost increase and this is true for many cars so I've been told. I'd choose to agree with it to justify the better fuel anyway haha Share this post Link to post Share on other sites
Kodename47 446 Report post Posted April 16, 2017 1) You'll be fine 2) You could flash back to stock, just need someone with an EcuTek cable. Shouldn't cost you. Probably no advantage to however, depends on how the mode 4 is setup, it may just be stock mapping anyway. Email Fensport? 3) You should be fine under warranty.

Paul 442 Report post Posted April 17, 2017 Inside of the fuel cap indicates that the car is to be run on 97-98RON fuel only. The car is fairly economical on that fuel though, so overall you shouldn't have to bear an increased cost. Share this post Link to post Share on other sites
Church 209 Report post Posted April 17, 2017 While, as manual states, car can run on 95 without any effect on longevity, due more knocking ECU tune with fuel trims will reduce power a bit and economy also may suffer. So imho better using 98 fuel. It costs more, but is used less, money-wise - almost same. Share this post Link to post Share on other sites

So imho better using 98 fuel. It costs more, but is used less, money-wise - almost same. Adrian at Fensport explained using less than super unleaded in one of the higher map settings wouldn't harm the engine, just that due to Knocking the ecu will re learn it self and decrease the horsepower to compensate. He explained that the car can learn itself back up to the higher performance when using higher octane fuel, but takes longer to gain hp than when loosing it. All said that's why MAP 4 is there so other maps don't get effected Sent from my iPhone using Tapatalk Share this post Link to post Share on other sites

Gringosteve 213 Report post Posted April 17, 2017 I use Shell out of preference, however I often go past a Tesco so sometimes substitute with their 99RON stuff. Worst case is my nearest station, BP with 98 RON Ultimate. Used 95 RON only once when I was in the middle of nowhere with no fuel and no options. It ran, but lumpy and a bit flat Sent from my iPhone using Tapatalk Share this post Link to post Share on other sites
surrey86 352 Report post Posted April 17, 2017 BP Ultimate is 97 unless they've changed recently. I tend to avoid it as it used to be a dirty word on scoobynet when I had an Impreza. Given the amount of import Impreza's that had blown up using it there was a lot of suspicion it was often somewhat less than 97 octane. 1 Gringosteve reacted to this Share this post Link to post Share on other sites

Your options are basically Shell VPower and Tesco Momentum, as I don't think anyone else sells 98+. Most places sell 97 octane super unleaded. FWIW I mostly use Tesco and it's fine.

The best fuel you can buy on the street is Shell V-Power Nitro. It's all I run my car on. I don't use Tesco, it would be a distant second choice over Shell.

Actually when I called fensport to inquire the installation and map the guy seemed to think it was a bit special of me to have 4 different aftermarket parts and said it will likely have some fitment issues but they would be able to solve it most likely, I did originally plan to put it in myself as it's not like it's moving parts or anything but if I shear a bolt I'm foooked so I decided against it Share this post Link to post Share on other sites
