It's Been A While

[ae111sr]

It’s been a while since I posted anything about my supercharged Corolla so time for an update.

I bought an Innovate Wideband Lambda kit in Florida last year and have just finished the installation in the Corolla. I removed a centre vent and fitted the gauge to an ally plate. I want to get it hooked up to the MoTeC for “closed loop” fuelling control but can be used stand-alone until that happens.

A full set of Cusco Zero2 coilovers are on order - these are not held in stock so are a special order from Japan and should be here sometime in August. I’ve gone for the softest spring option and the fronts have comber adjustable pillow ball top mounts.

There is a set of 16” x 7 Rays Volk Racing TE37 wheels on order but because I want a non standard colour (Mercury Silver) they are a special order from Japan and won’t be here until October. They will have Toyo Proxes T1-R on them.

My wallet is empty.

its strange your wallet is empty....because our works is quite full

I guess babs will lose her vent now when you go out

its looking good John as always B)

Innovate Wideband Lambda kit

dont know anything about them, could you enlighten?

working on the GXi at the mo trying to get the bodywork up to scratch - want GZE in her, hopefully next year?

Copycat :P just joking that will set the car off nicely

What is it and what does it do?

Modern cars have an air/fuel sensor inserted into the exhaust just before the catalytic converter which measures the amount of oxygen in the exhaust gases after combustion. The signal is sent to the ECU where the program adjusts the amount of fuel injected. Most cars have what is called a narrow band "oxygen" sensor which can only read a narrow band of lambda values and the signal is used for adjusting the fuel when the engine is idling. Wideband sensors can read a much wider band of lambda values and the signal can be used to adjust fuelling at all revs. With a standalone system the signal can also be used to drive a gauge to display lambda values.

They are very like the Rotas that are already on there - that's why I like them.

i know about lambda sensors - most have one after too! so whats the advantages over a normal sensor? what's in the kit? hope you dont mind the questions but if you dont ask............

sounds good john, what you goinf to do with your old suspension setup (hint hint)

This might help clicky

Still waiting for the Cusco to arrive - then it has the be fitted and set up properly. I'll PM you about my suspension when the Cusco gear has been done. B)

Biggest problem with the Innovate was fitting the sensor in the exhaust. Toyota one is press fitted to a flange and then that's bolted to the pipe. The one supplied was a screw fit - though they do supply a threaded boss to weld on. My son removed the old sensor from the flange and welded the boss to that then screwed the sensor in and re-fitted the flange to the pipe.

From the readings I've seen the MoTeC has been mapped pretty well - on part throttle it's running lean for ecomnomy - floor it and it goes slightly rich - just as it should be. Power and economy - can't fault it :D

Looking forward to seeing your car - been following the progress - looking good. :D :D :D

I too have the Innovate... cracking piece of kit IMO... they say it should Ideally be sitting at 14.7 which is the correct amount of air (14.7lbs) to 1lb of fuel.

What is 'mixture' and why do I care?

For gasoline to burn it needs oxygen.

For the most complete combustion gasoline usually needs to be burned at a ratio of 14.7 parts of air to 1 part fuel. This air to fuel ratio (AFR) is called stoichiometric or Lambda = 1. This is just a ratio between air and fuel. For example all of the following are at the same AFR:

7.35 lbs of air to 0.5 lbs of fuel

14.7 lbs of air to 1 lbs of fuel

147 lbs of air to 10 lbs of fuel

Obviously the amount of air and fuel being burned is totally different between each example but the AFR for each is identical.

14.7:1 AFR is normally considered the best trade off between emissions, fuel economy and power production.

Running LEAN is when your AFR has more air to it. The AFR is greater then 14.7:1 (Lambda >1) for example 16:1 AFR is lean. Running lean increases emissions, increases heat, usually increases fuel economy, reduces power and increases the chances of knocking.

Running RICH is when your AFR has more fuel to it. The AFR is less then 14.7:1 (Lambda <1) for example 13:1 AFR is rich. Running rich increases emissions, usually decreases heat, decreases fuel economy, increases power (to a point), decreases the chance of knocking. Running rich for long periods of time can cause deposits to build up on the plugs and O2 sensors (fouling) and can clog your catalytic converter. Maximum power is usually obtained running around a 12.3:1 AFR. Going richer then that will cost a little power but you loose less power then being leaner then

The Innovate kit comes in handy for allowing you to keep an eye on how your car is performing.. well, up to a point anyway.. for instance I noticed that my car was very nearly stalling when at idle and I then noticed the AFR was sitting at 18.5 upwards... so a quick check led me to a hose that had popped off, fixed it back on and all is good and we have a 14.7 at idle once again... like I said.. handy piece of kit :)

Mostly John and me just like watching the cute little lights dancing round the gauge

[ae111sr]

Davey,

And you can change the colour of those cute lights too

[cfc1]

Mine goes purple quite often :D :P

i just dont want to ask :shutit:

[ae102]

that makes sense now - clever piece of kit, can see the advantages especially on a highly tuned car. something else on the wishlist! helpful for home diagnosing. them fittings on the older Corolla's are a nightmare, why they hell they didnt use the screw in type is anybodies guess - they like giving us these challenges?

[ae111sr]

I would say they would be most useful on a car with a programmable ECU - that way you have complete control over the air fuel ratio not like the standard ECU

pretty useless otherwise other than to see if things are running right, although there is a degree of self learning in modern ECU's but dont know how they'll adapt to take proper mods?

also helpful to see how good the mapper was?

got a few mods on the go at the minute for the 2ZZ, that bit of kit would certainly help see how things are running but the next step is, well a Motec.

Tarox didnt do the discs for mine but have ordered some very tasty Jap carbon ones and the carbon pads are being made custom - first E12 in Europe with a set! have to see if Fensport will give me a credit note for the TRD pads?

[dawesy]

the system is very expandable too.

i have the lc1 and the auxbox on the rolla.

the auxbox is set up to datalog lateral and accelerative G force, speed and MAP (inbuilt 3 bar map sensor).

you can also display any of the input channels simply by daisy chaining another display unit into the system.

top quality kit.

glad to see development of the rolla continues john

It's a never ending process - as you know

My Corolla - made in Japan - perfected in Wales

[ae111sr]

Look what I got on the weekend - nice box :)

Nice contents too :) :) two sets like these

and this is a work of art

Should be fitted to the supercharged Corolla by the end of the month. Shame to put them on the car - they will get dirty under the wheel arches

[AE_92]

very nice ae111sr the box looks really kool with the jap writing on it B)

why is it gonna take soo long to put on??

ps You better hang on its gonna be a bumpy ride

[ae111sr]

I'm not able to do much work on the Corolla as both my knees are shot. One has been replaced and I'm waiting for the other one to be done. Fitting and setup will be done by the guys at Track Developments who did the original chassis analysis for me.

[4afte]

sorry to hear about the knees old chap (would've saved you time) glad that it's turned up (mainly because you'll have to take off your old setup! )

which will be just in time as i'll have my rolla back by then hopefully (long story) i need to stop the rolla from squatting under all the torque!

[ae111sr]

I've managed to get it booked in for next week . Do you know how much weight is on the front wheels. My front suspension was designed for about 780 Kg on the axle. Much more or less than this would make the springs / damper unsuitable.

[dawesy]

is that per wheel or per end?

if per end you should still be OK as the GZE with gearbox is only about 20-30kg heavier than the 4A-GE
