Getting Better by the Day

More updates from Toby today.

Boost was slightly increased to 1.1 bar and the Slowtra registered 271 hp at the wheels and 298 hp at the crank/engine. Torque is equally impressive @ 34.19 kg/m or 335.4 Nm. For those of you who can remember the Slowtra's power output at the stock engine when I last dynoed it was 106 hp and 150 Nm torque. This means the spankin new not fully break-in engine is now making close to 300% more hp and > 200% more torque. ... And there's more power to be had. Should I still call my car "The Slowtra"?

Got this from Toby earlier today. 245 hp and 298 Nm of torque at only 0.86 bar of boost.

This is just with standard RON 97 fuel, a run in map, engine rev limited to only 6000rpm and with no water injection. Oh and power is measured at the wheels. This means 245 hp translates to 269.5 hp at the crank/engine assuming a transmission loss of 10% is factored in the calculation. Imagine what 1.2 to 1.5 bar of boost will result in. I believe 300 hp will be a walk in the park once the engine is fully run in and thoroughly power mapped by Toby with water injection. Vroooooooooooooooom!

It's Alive!!!

Next steps include tuning a proper idle and run-in map. That's all I can say at this point :) Stay tuned...

Brain Transplant

The main flying lead harness for the Slowtra's new brain/ECU is finally ready. This connects the new ECU to the car's wiring harness. This method is easier without having to rewire the entire car.

As mentioned previously the ECU I am using is the latest Autronic SM4 version 1.09. The SM4 fits nicely into the stock ecu box/cover.

The SM4 comes with its own build in 3.4 bar MAP (Manifold Air Pressure) sensor so the stock performance limiting mass airflow sensor is no longer required. Going higher than low boost would have maxed out the crappy stock MAF sensor anyway. Specifications for the SM4 can be found in the excellent MRM Racing (Autronic's Swedish Distributor) website. Still waiting for Autronic to update their own not so excellent website.  Needless to say the SM4 is a fully programmable ECU that does not require the stock ECU unlike piggyback fuel and ignition controllers like the Greddy E-Damage.. sorry E-Manage. Comparable equivalent ECUs include the Haltech Platinum Sport 1000 and Motec M400. Can't go wrong with either and the ability of the tuner or person doing the install and ECU mapping is more important likewise aftersales technical support. Some notable features that lead me to decide on the SM4 include:
  • Excellent resolution i.e. fuel and ignition tables have 32 rpm and 16 load site axis. Both load and rpm sites are freely selectable.
  • Transient settings for precise fuel delivery through rpm and load range.
  • Individual cylinder trim for fuel and ignition.
  • Ability to self (auto) tune.
  • Multiple boost control strategies including both internal and external wastegate snails. No need to buy a separate boost controller. Ability to alter boost according to selected gear.
  • Launch Control (two step rev limiter based on vehicle speed).
  • Flatshift (change gears without clutch at WOT using standard gearbox).
  • Traction control with different settings for dry and wet weather.
  • Antilag (keep turbocharger on boost during gear changes) with turbo cool down function - Don't require this for a road car but if one day I turn the Slowtra into an all out kereta perang..
  • Ability to data log.
  • Compatible with my AIM MXL Strada dash .
  • Master Tuner Toby experienced with installing and mapping this ECU.
The Slowtra is very very close to being started with its new brain. A problem with the trigger pattern resulting in only 1 cylinder firing has hopefully been rectified and the start should commence anytime now.

More Goodies!

This just arrived after more than 3 months. Can someone tell me what it is?

Here's a hint :)

Gearbox Goodies

Some ancillary parts I ordered for the 70A gearbox many many moons ago which finally arrived only after the gearbox had been fully assembled and mated to the engine on the Slowtra. Sigh :( All parts are from Japan and on back order hence the long lead time of more than two months.

Side cover and gasket

Rear cover. I also ordered the O-ring for the rear cover but it remains on back-order.

Brand spankin new reverse idler gear shaft, snap ring and O-ring seal.

Close up of the reverse idler gear shaft.

You can see the condition of the ones that came with my gearbox. Still perfectly usable but I wasn't too happy with the aesthetics especially the rusty reverse idler gear shaft. You know me la. Now need to convince Toby to install.
