↔️Peak Boost Pressure 19psi / 230g/s flow
↔️Linear throttle response
↔️DBW Logic
↔️Knock alert
↔️No boost drop on gear shifts
↔️EGT manage

Whereas the SH9 was gifted with a 5spd 5EAT gearbox the TCU coding is a bit different from the one on the legacy GT & to keep the ECU/TCU happy, aligning the signals makes things easy for the transmission.

For years we have been developing some IPs that we use to customize the maps to suit our approach on some key tuning strategies that ensure full optimization of the DBW.

Stopped at that after getting knock alerts informing me that we have reached the strength capabilities of the fuel.....

Has potential to push for more perhaps next phase is to strengthen the rods/pistons and add in the m**h system. Should be more than enough to max the turbo at this altitude.

Thanks Jeffer for reaching out to us for our services.

WRX with some Stage 1+ mods. Had to suspend the session after analyzing some key sensors & mechanicals not working as they should.

This will make some nice street jam. Stay Tuned!

Heavy hitters on the loose folks. What a weekend full of adrenaline.

The shopping cart battled to the semis and settled for P4 today's draggy. Forget about the captions floating around. Make a small mistake on the dig and you will be taken out.

Full weight with stashed packages in the boot best draggy time 12.59 1/4m.
Well done & our congratulations are in order Sammy Njoroge

Forester XT from Star Cluster Garage.

An asthmatic FA20 almost on the verge of converting itself to a "blackie".
Its damn slow. For those who can't relate, Blackie is a bike; Was soo popular with photograhers & Charcoal carriers...😎. I hardly come across them nowdays.....

Safe/Limp Mod swiftly kicked in....

The FA20s really really demand premium legit fuel for it to run efficiently with performance even at oem level. Once these units land here the kind of culture shock these engines experience for lack of a better word is unimagineable.

Safe/Limp Mod galore!

There many ways to address these gaps & we got the medicine for them.

✅️ Bugs fixes
✅️ Engine environment aclimatization
✅️ Extracting a few juices from the motor with our fuel isn't bad.
✅️ Aliving the CVT Transmission
✅️ ....& many more

Taking less myths & advises will save you alot of agony...😎

One of the key things that did put Mitsubishi Rally on the edge was their advance 4WD technology.

Am still developing a sweet spot that will be ballpack for both the driver & the car with more focus on entry & exit on corners.
...and in a nutshell

✅️Deceleration slip strategy
✅️Ramp up acceleration
✅️High speed straight line etc etc .........

All in all abig thanks to the entire team for a well coordinated effort & the support I got that made my work easy.

My congratulations are in order to the racing team.

We have some cleanups to polish.....cracked manifold bleeding lots of boost, some vacuum pipes issues etc etc......

Traction comparison then vs now after making some slight changes just for todays event.

Traction management is one of the critical things rally cars rely on when it comes to disctating vehicle handling, hydraulic control under different preloads, turn-in Response, under/oversteer & tractions across various surfaces.

Today we made clean passes & collected valuable data for analysis.

Issa Amwari is definitely coming back stronger.
