Both maps have more oil everywhere compared to stock. Map 1 is the fully tuned map delivering maximum performance. Map 2 has less ignition advance and more fuel than Map 1 and is softer everywhere. Map 2 is the 'safe' map we suggest using for prolonged high speed riding, deep sand, or if you want to temporarily reduce power in very technical terrain.\u003c\/li\u003e\r\n \t\u003cli\u003ea new NGK spark plug, better suited to the improved power the engine makes with this kit\u003c\/li\u003e\r\n \t\u003cli\u003e50mm bolt and spring necessary to do the 'idle screw mod'. Not always necessary to install but we supply it just in case.\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\nThis package makes an astonishing difference to the TPI and offers the following gains over a stock bike:\r\n\u003cul\u003e\r\n \t\u003cli\u003emuch more torque at low\/mid revs, where you need it most, with a nice increase in power higher up in the rev range as well.\u003c\/li\u003e\r\n \t\u003cli\u003edrastically improved 0-1\/2 throttle performance\u003c\/li\u003e\r\n \t\u003cli\u003emore oil than the stock maps for improved reliability... the stock 20\/21 maps give significantly less oil than the previous year models.\u003c\/li\u003e\r\n \t\u003cli\u003e2 ignition maps: hard and soft. The stock map switch works like normal to select between the customised maps.\u003c\/li\u003e\r\n \t\u003cli\u003emuch smoother, crisper power deliver at part throttle.\u003c\/li\u003e\r\n \t\u003cli\u003emuch less 'pipe bang'... this is the annoying \"dang, dang, dang\" noise the engine makes on deceleration. Its generally harmless but very annoying and makes some stock TPI bikes unpleasant to ride at times.\u003c\/li\u003e\r\n \t\u003cli\u003esafer air\/fuel ratios at high rpm and large throttle openings so the engine is safer during prolonged high speed running\u003c\/li\u003e\r\n \t\u003cli\u003ebetter throttle response\u003c\/li\u003e\r\n \t\u003cli\u003eyou can ride in a higher gear with lower revs in many situations and use the extra low end torque to get you places with less wheel spin and much less clutch work\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\nThere is no change to reliability with this setup... the ignition maps, air fuel ratios and combustion chamber designs are similar to those we have run very successfully for years on modified carb models... after all the TPI engine is basically identical to the previous carb engine, except for the fuel injection system... as a result we know exactly what it can or cant handle in terms of performance mods.\r\n\r\nIn order to change the stock ECU data we have spent hundreds of hours developing our own process for accessing, changing and reloading the ECU data. TSP was the first to develop a tuned package for the TPI bikes and we have years of experience testing and tuning fuel injected 2 strokes prior to the release of the TPIs in 2018.\r\n\r\nAll ECU features work normally, including oil injection, fan and warning lights. There are no issues with hard starting and no need to tune via apps or software... just install and ride!\r\n\r\nWe provide an idle setting bolt that can be installed if you feel the need to change the idle speed or air screw setting after fitting the kit, however the vast majority of bikes will run fine without it.\r\n\r\nThis kit has been developed to work with the stock exhaust and almost makes aftermarket exhaust systems obsolete for the TPI... the head and ECU give a WAY bigger gain in performance than any aftermarket exhaust can offer, and theres no trade off by taking power from one area to improve power in another, as usually happens with pipes.\r\n\r\nWe supply fitting instruction plus recommended settings for the air screw and powervavle preload.\r\n\r\nThis is the ONLY complete solution currently for sale on the market that addresses all the necessary TPI issues... head, ignition and fuel. It is also the MOST COST EFFECTIVE solution by far. All other solutions are either more expensive or only tackle part of the problem. In order to address all the necessary issues using other parts you would need a programmable ECU, an aftermarket head, a new plug and an idle screw... buying all these separately adds up to roughly twice the cost of our package!\r\n\r\n \r\n\r\nThe 250 TPI kit is available in the following combustion chamber designs:\r\n\u003cul\u003e\r\n \t\u003cli\u003eMEDIUM COMP - this head and ECU tune suits the majority of trail riders and racers who want better bottom and mid power and a small gain up top as well. Much tighter squish clearance than stock. The power delivery is much stronger and more tractable than stock and suits a wide range of riding conditions. Suited to 95 or 98 RON fuel. This setup maintains a great spread of power and still revs out freely up top.\u003c\/li\u003e\r\n \t\u003cli\u003eHIGH COMP - Requires 98 RON fuel (91-92 in the USA). Squish clearance is much tighter than stock. Gives maximum bottom\/mid power but less overrev than the medium comp head. More aggressive power delivery down low and tractors up hill climbs with ease. Makes your 250 feel like a 300 down low but the bike overall still feels light and more flickable like a 250 does. This is the setup we run on our 2020 250TPI and its the most versatile bike we've ever owned! At high elevation above 1500m will run similar to the Medium Comp design at sea level.\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n \r\n\r\nhttps:\/\/www.youtube.com\/watch'v=nLsTroHT1ws\u0026amp;t=342s\r\n\r\n\u003cstrong\u003eHOW TO ORDER:\u003c\/strong\u003e\r\n\u003cul\u003e\r\n \t\u003cli\u003ePurchase the TPI Power Kit by placing an online order, select your desired combustion chamber and payment method\u003c\/li\u003e\r\n \t\u003cli\u003eSend us your stock ECU with a copy of the order confirmation you receive via email\u003c\/li\u003e\r\n \t\u003cli\u003eOnce we receive your ECU we will reflash it and return it with the head, plug and idle bolt.\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n \r\n\r\n\u003cstrong\u003eEuropean orders:\u003c\/strong\u003e\r\n\r\nYou can place your order as above.\r\n\r\nWhen you are ready to ship your ECU to us email us at info@twostrokeperformance.co.uk and we will send you the customs info required and the best carrier to use.","brand":"Rutherford Racing","offers":[{"title":"High Compression","offer_id":42374365806667,"sku":"8181","price":479.19,"currency_code":"GBP","in_stock":true},{"title":"Medium Compression","offer_id":42374365839435,"sku":"8182","price":479.19,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/5171\/7707\/files\/IMG_9696_3d5314ce-13d4-4573-96fb-8c4c0e045762.jpg?v=1785514232","url":"https:\/\/rutherfordracing.co.uk\/products\/tpi-power-kit-suits-2020-ktm-250tpi-and-husky-te250i","provider":"Rutherford Racing","version":"1.0","type":"link"}
