![]() Numerous phone calls and emails are to no avail. In fact it's been 1 year since Dan Hull A&S Racing was Paid In Full (Dan COD's everything, now I know why) and I still haven't received all the pieces to this POS Kit. I wasn't able to use 1 piece of this POS Apex Kit Dan Hull A&S Racing in Michigan sold me and another vendor here on the forum. I bought (2) A&S Racing Apex Turbo & Mounting Kits for over $11,000.00 (NO engines)!!! Whether you've just hopped on your Yamaha for the first time or been riding it for years and want to upgrade, a Worx Tune is always a great idea As one of the easiest upgrades to make, the upgrade process is super straightforward All you have to do is remove your ECU, send/drop it in to us. I won't break my motor or tranny mounts like ALL the other swap kits have done. I had my APEX-XP mounts engineered and designed the Yamaha way.ĭo it once and do it right the first time. According to them, they are not offering a reflash on the 2020 R1 at this time. They said that currently the 2020 R1 ECU is locked and their ecu flash vendor has not been able to unlock it yet. I utilized the millions of dollars, years of testing and the R & D that Yamaha spent on engineering & designing the engine and transmission mounts. Talked with Superbike Unlimited on the phone today. All these so called engine swap companies kits have designed there kits to hard mount the engine and transmissions in the XP. ![]() The engine per Yamaha wasn't designed to hard mount to the transmission in any way, shape or form. You damn sure don't reinvent the wheel when you install a APEX in your XP. Yamaha mounts the engine and the transmission separately for a reason. When you buy a sled (I bought a Brand New Sled) look and see what millions of dollars in Yamaha engineering has designed to mount the engine and transmission in the sled. I don't know about a Z 1, I'm installing a Apex. If you don't want a hacked up mess then it's going to cost you big bucks to install the APEX correctly. I agree with brian126, check the oil level just to be sure, but you probably just confused the ECU.Amen Gary. What probably happened is when you hit the kill switch, you dropped the engine below idle, and since you fired it back up before the engine stopped, the ECU flagged the sudden drop in oil pressure and threw the OP-LO warning. A low engine speed will drop the oil pressure significantly. ![]() The motorcycle engine that powers the Apex doesn't like low RPMS's. Makes sense they'd do the same thing on the Apex. The Phazers won't start unless the ECU sees enough oil pressure, which is why they crank for a while sometimes. Yamaha uses some electronic wizardry on their 4-strokes with oil pressure. Sounds like the OP-LO code flashing upon startup is normal. Fully compensated for the closed loop routine below 5k rpm. 'T' mode mapping remains stock but we made slight adjustments to the AFR (Air/Fuel Ratio) in 5th and 6th gear producing a value of 13:1 as opposed to 12.7:1 (factory) Better advance maps over both cylinders 1 and 2. I have noticed at each start up of all three of our 2011 Apex's that the OP-LO comes on but if you wait about 10 seconds it goes off and all is fine." Greater fuel efficiency in 'S' mode maps. If it sees low oil pressure for "X" amount of seconds it can also shut the motor off. Or it will activate an RPM limiter that will keep the sled from going above about 3000 rpm or so. This flash version targets customers who pay attention to fuel octane quality and who are willing to use premium pump gas all the time. It will either slow the rpm of the sled down slowly until it reaches an idle (if you are cruising at a higher rpm). "It means that the engine oil pressure is low. Did a quick search on Totally Yamaha and found this from Srxspec (which is Ulmer Racing):
