Uses open source HondaFlash program for diagnostics and to read/write tunes and Tuner Pro to edit your map (may require purchase of additional ECU definition files). Supports tuning on CRF250R, CRF450R, CBR600RR, CBR1000RR, and lot of other Honda models and diagnostics and most EFI bikes utilizing a 4 PIN DLC connector. We highly recommend the HondaECU software from MCU Innovations (which can be found here: ) This kit Supports HondaFlasher and MCU Innovations. (Already have a cable/interface? Purchase just the adapter cable here!) FuelTech specializes in high performance engine management systems and parts for race cars, watercraft, motorcycles, trucks, off road, and more. Therefore, the most pro-active steps will be taken beforehand to ensure the minimum amount of negative outcome-it's really easy to do that now and avoid problems as compared to when there's already an issue that may have caused and compounded other issues (so the additional investment is small).Diagnostics and Tuning adapter - Honda HDS/DLC to OBD adapterįinally - an open source tuning and diagnostics option for your Honda motorcycle! This listing is for a FULL kit - includes the Honda adapter cable and our FTDI based EuroFlash motorcycle interface. If the same bike takes a road-trip to the center of the country or the hot South, there is cause for mild concern. The opinion of men smarter than I is at Milwaukee altitude (low, dense air) and temperatures (not super-hot) there shouldn't be any problems. The ECU is set for dual pipes (no scavenging effect) and very low idle. ![]() Switching to high-octane fuel will slow the burn and hopefully a "pop and die" will turn into a controlled burn, buoying the IAC setting and the bike not stalling out.Ī set of challenging conditions of concern is hot summer air coupled with slow city driving and idling on black asphalt that is being cooked by the sun, sitting at an extended stop lights with other vehicles also using the O2. ![]() You can get the Woolich Honda ECU kit for 384 and flash your own ECU with USB and a laptop. This is the minimum fuel usage setting, and at very low idle under challenging conditions the engine may miss/stall. Any other reputable tuners that I missed. The reason for using low-octane fuel during the relearn process is so the IAC is mapped to what will keep the engine running smoothly. It's finally warm enough up here for the engine to reliably traverse the full temperature range from "cold" to "hot" (as indicated by the cooling fan turning on and lowering the engine temperature, effectively creating a "maximum") at idle for the Idle Air Circuit (IAC ) re-learn (reset/auto-tune) procedure after the tuned ECU replaces the stock ECU. To help make sure things go properly the forum instructions for each modification are printed, plus there are forum members smarter than me on speed-dial, so should be fine.Īfter the install I'll run the standard octane for tuning purposes, then switch to rich after everything is smooth to prevent engine stalling at the very low idle setting (as planned out with Ken and Don's expert help). I'll be putting in Marilyn's brain from Ken BusKill this weekend along with PAIR block-off plates, so we'll see how that all goes. If it wasn't for the odd pulse, even with a wide-open exhaust there'd probably be less pop. Rogue7 suggested it was because the exhaust flowing through the stock pipes was suddenly hitting the very open and large Cobra 3" cans, causing a differential pressure pulse and therefore more decel popping, and with richer fuel comes more pop. Octane slows the burn and prevents micro-detonation in the cylinders, also tends to keep the cylinder head and valves cooler (all good things). I noticed with Cobra slip-ons and "stock everything else" the higher octane pops more on engine braking under load (using the engine to slow the Fury). The specs he has are dynotuned, so you can just let him use those, or customize it how u like.Ĭhat up as he is the Grand reflash master. its the best 5 day downtime you will ever have for ROI!! a 30-60 minute reinstall ( coz you want to ‘re-learn’ the ecu afger you putit back in. Its a 15-30 minute removal of ECU, overnight to Guhl with specs and they will call to confirm specs/credit card info, and do it within 24-48 hrs and overnight it back. ![]() fair compromise is 750/800, and throttle response is UNBELIEVABLE!! The flash will also push the rev limiter way out, so if you need to pull out into traffic fast, you probably cant twist it far enough after reflashing to get it to cut off. basically you are advancing timing, which stretches the gear, adjusting the temp setting so fan comes on 20* earlier (extends engine life), you can lower the factory 933 idle, some go down to 600. the ECU flash can be done by Don Guhl, and will include lifetime adjustments.
