Tuned Replacement BMW ECU

We are happy to announce our new partnership with Wellso Tuning! Deejay from Wellso Tuning will be doing all custom tunes for us, making the most of his extensive tuning experience. We are also adding new tuning options like Launch Control and pops and bangs! All ECU base tunes include a performance tune along with EWS Delete, MPH limiter and limp mode RPM limit deletes. We also lower the target coolant temp; these engines come with high coolant temp targets, but if you are tracking your car or running hard it gets hard for the cooling system to keep up. This tune is a complete solution to getting the most out of your BMW. 
 
Getting a custom tuned ECU is now simple. Just order and we will ship you an ECU that is ready to drop in and go. Instructions can be viewed HERE If you would like to send in your core and save $50, please see this listing HERE.
 
Buy From the BEST; we have been involved in tuning these cars for years and the speed of our Time-Attack E46 proves this point! Full tech support included, we are here to help your right foot make you smile! We have a ton of experience with this platform and have made over 700hp using the aluminum M54 block. Deejay is one of the best tuners we know, is very technical with his approach and specializes in BMW tuning. He takes the time to remove each ECU from its case, inspect it and then load a tune onto it that is specifically made for you depending on which options you want. Truly a custom tune, no off-the-shelf BS. This is much more than most tunes which just change the throttle map. We change VANOS, timing, eThermostat,  PVS and more maps for maximum performance. 91 or 93 octane fuel is required for best performance, otherwise knock sensors will remove timing. 
 
These ECU's have the EWS deleted so it can also repair vehicles with a bad ECU or EWS system without the need to visit a shop for expensive programming, or be used in an engine swap project. Just plug it in and go. There is no downside to this for cars without this issue. 
 
Now, lets go over the options:
 
ECU/Engine Version: This is easy to check by removing the ECU and looking at the label. Instructions for this found in the link above. 
MS42:  comes in all E46 323 and 328 models. The 323 has a 2.5 and the 328 has a 2.8. 
MS43 comes in the following models, with the 325 being the 2.5 and the 330 the 3.0.
All E46 Xi models, regardless of year
E46 325 and 330 vehicles built before mid-2003. If your MAF sensor has 3 wires, you are MS43 
All E39 525 and 530 models
All 2003-2006 X3 E83 models
All 1999-2006 X5 E53 models with a 3 Liter engine
MS45.1 comes in all facelift E46 models and other updated MS43 vehicles. We can tune these also, but we cannot provide a drop in unit, you must ship your ECU in. You can order this service HERE
 
Intake Manifold: Select which you'll be using, we tweak the VANOS and other maps to get the most out of cars using our M50 manifold swap which can be found HERE. This will also allow you to use the normal E36 air temp sensor that comes with the m50 manifold instead of retrofitting the original plastic M52TU/M54 temp sensor. 
 
Rev Limit: Get that motor singing! This is a great option especially if you're using headers and/or a M50 manifold. We do not recommend raising the rev limit above 6750 on vehicles without an oil pump solution. We offer several oil pump solutions in our online store. 
 
Increased Idle RPM: This is a great option if you have a single mass flywheel that makes the transmission chatter. Slightly raising the idle RPM makes this go away. 
 
Headers/SAP: If you are running headers, or plan on installing them later, select yes here. We will delete the monitoring of the downstream O2 sensors which monitor catalytic converter efficiency (removed with headers). We also open up the maps a bit to make up for the engine breathing a bit better. You can also remove the bulky secondary air pump with this option. With these options you won't get the check engine light when installing headers for some great power gains. Off-Road use only. 
 
Launch Control/Burble Tune: This is just awesome. A must for any performance build. Video HERE
 
Launch Control- When the clutch is fully pressed and the gas pedal is floored quickly and held there the Launch Control will hold the RPM at 4k until you drop the clutch! This works on manual cars. Can be loaded on an auto car with no ill effects, it just won't work. 
 
Burble Tune- This makes your car sound like a real track monster. Available in three levels of aggressiveness of exhaust pops and crackles on deceleration and shifts. Level 1 is a modest burble, level2 gets a bit more rowdy and level 3 is a whole lotta bangs!
