Have you ever been confused which remap will fit best to your reuirements? Do not limit yoursef and get all options in single ECU!

I am working on new unique LETO ROM for our vehicles which allow you personalize ECU settings to fit your needs.
Here is preview of features included in new release.

New release of LETO Tune includes multiple user selectable modes for different Power Levels and Launch Control settings.
Modes have different settings not just for injection quantity but for boost and turbo VNT control too.
You can switch between modes easily by depressing clutch pedal and pressing cruise control lever UP (for Power Modes) or DOWN (for Launch Control Settings).
When you depress clutch pedal and press lever in desired direction for first time, ECU will blink index of actual selected mode on gauges (CRUISE LED). Next time you press lever in same direction, while you are still holding the clutch pedal, ECU will increase MODE + 1. Once you reach MODE 5 and press lever again ECU will roll to MODE 1. So you can rotate and combine 5 MODES in each direction - UP / DOWN.

Multiple Power MAPs switching (Cruise lever UP):
- MODE 1: Max Performance ~220HP / 525Nm @ 2bar Boost
- MODE 2: Same as MODE 1 + HARD CUT Limiter set at 5150RPM
- MODE 3: Mid Performance ~210HP / 500Nm @ 1.85bar Boost
- MODE 4: OEM Style mode with corrected performance curve
- MODE 5: Low emission mode with limited power

Multiple Launch Control Settings(Cruise lever DOWN):
- MODE 1: Launch Control Disabled
- MODE 2: Launch Control set to 1900RPM
- MODE 3: Same as MODE 1 + HARD CUT Limiter
- MODE 4: Launch Control set to 2500RPM
- MODE 5: Same as MODE 4 + HARD CUT Limiter

Added Engine protection:
- Launch control is denied until engine temp reach desired value
- Power is reduced until engine reach operational temperature
- Power is reduced when engine overheat and temp exceed desired value

We are still working on improvements and planning to add another features soon 🙂

this is going back a long time but FR Wilk among others helped me learn the tuning and coding of E30 bosch motronic. the websites are long gone these days but you can find some of the old sites via web archive. i helped him out with the AFM maps pages.

RIP FR Wilk

i need a guinea pig. any volunteers with an e30 318is (m42b18) with 175 ECU. need some feedback on a chip for this engine. £30 via paypal (posted within the UK/EU) and your feedback on how it performs compared to standard before officially starting to offer chips for this car/ECU.

first come first serve. i can spare 1-2 chips at that price for testing and feedback.

Bored with DPF and EGR fault codes and only 175-177bhp and 300lbft of torque on your is220d? have no fear LETO is here. how about 231-232bhp and 380+lbft of torque on a totally standard car with the exception of having the internals of your DPF removed. we are working on hard cut rev limiters, launch control and flat foot shift. ask your local remap company if they can do that.

Come to LETO for the best, serving all of the UK and EU.
