Since we’ve become an ECUTek tuner we now have the ability to play with the GTR. \u00a0Enter the following 2014 GTR.<\/p>\n

\"side\"<\/a><\/p>\n

 <\/p>\n

The 3rd Gen R35 GTR, each year is better and better with improved refinements top to bottom.<\/p>\n

The goal for this GTR this time around was to get it tuned properly for 91 octane as the GTR is meant for a minimum of 93 octane from the factory. \u00a0Knock is high on our wonderful 91 octane fuel so things needed to change in the tune. \u00a0Besides tuning for 91 octane we also went to work by upgrading this GTR to run ethanol fuel. \u00a0We upgraded to 1300cc fuel injectors and also replaced the secondary fuel pump to a Walbro 485 pump. \u00a0We were interested in seeing what a bone stock GTR with a tune for both 91 octane fuel and ethanol would do.<\/p>\n

\"engine\"<\/a><\/p>\n

Ready for the injector swap.<\/p>\n

\"top_feed_injectors\"<\/a><\/p>\n

Our 1300cc fuel injectors.<\/p>\n

\"fuelpumpassem\"<\/a><\/p>\n

Factory fuel pump assembly that houses the twin pumps.<\/p>\n

\"fuelassemapart\"<\/a><\/p>\n

Stock pumps sitting together, we installed a single Walbro 485 to replace the secondary pump. \u00a0Since one Walbro can support 600whp on ethanol we felt leaving the primary pump stock more than adequate for stock turbo power levels.<\/p>\n

\"stock\"<\/a><\/p>\n

Baseline on the stock tune and stock fuel injectors.<\/p>\n

\"tuned91\"<\/a><\/p>\n

Tuned on 91 octane tweaking boost, AFRs, and timing to make it happy and not knock (on the new 1300cc fuel injectors)<\/p>\n

\"tuned_e85\"<\/a><\/p>\n

Tune on ethanol for impressive gains. \u00a0All on a bone stock GTR (other than injectors, pump, and tune).<\/p>\n

\"all3\"<\/a><\/p>\n

All 3 runs plotted together to show the differences. \u00a0Next up, exhaust mods!<\/p>\n","protected":false},"excerpt":{"rendered":"
