1g-gte Piggy Back Options

[Karma_Supra]

that and the fact that its not much more $$$ for a standalone as opposed to a piggy back ecu
hit up jamie - forcefed performance, he has some good prices for microtech

Prices for the Emanage ultimate can be cheaper (than what I've seen in this thread) if you're prepared to wait for postage and buy them from Japan.
eg Using Nengun, when I priced up the 3 items (E-Manage Ultimate, wiring loom & software) it came to $746.42 + $70.38 shipping = $816.80 to your door.

I am in the same situation as Z2TT (same car too!)

Is there much difference in the actual tuning of said ECUs, and do any tuners prefer a certain ecu? (i.e. laptop connection vs hand held controller)

Also, who is a good tuner in the southern area of adelaide? I have heard good things about Boostworx, especially in regard to Toyotas

Ok, I took a look at some microtech products.

There is :

LT8S - $1149
LT10S - $1254
LT12S - $1569.

Would the LT8's or LT10s be a good choice?


How is the timing controlled with the stock ECU setup, is the distributer controlled by the ECU? to advance/retard timing could you just turn the distributer cap like on older cars or would you have to reprogram the ECU?

If there is any difference, how is the timing controlled with a microtech compared to a stock ECU? Just a bit confused on this thats why im asking.

Thanks

regarding tuning out south way
graham west workshops are really good too

Boris,

Turning the Distributor will alter your base timing, Because I run 1.25 Bar of boost My base timing had to be reduced from stock by 2 degrees to stop it pinging and hitting the knock retard. This means the car is less response all the time, rather than just pulling timing out at high RPM.

Using a fuel only controller such as a SAFC gives you limited fuel trim ability but doesn't allow you to address any of the timing concerns.

Using a piggy back like an EManage or the Xede give you that much desired timing control. Typically you can add timing over the standard amount at low to mid RPM when you use a good 98 Octane fuel and hence you can acheive much better responce and low to midrange power.

The rule of thumb is that a Piggy back ECU is limited to a change of around 20% over Standard. Its not gospel, just a good way to evaluate if what you want to acheive suits a Piggy back or requires you to go to a full Stand alone ECU. IE if your power desires require injectors more than 20% bigger than Stock your probably starting to stretch the limits with a Piggy back ECU. The Gen 3 Injectors are 312cc, and I believe mine are peaked at the 193kw it makes now. My new injectors are 372cc so almost right on 20% bigger. My turbo's will prevent me making much more peak power than I do now but the revised fuel and timing control will greatly improve the way it responds.

A piggy back ECU is of course much quicker to instal and also much quicker to tune than an aftermarket ECU as there is less to set up. Your stock ECU still does your Idle and all the basics. Hence why the Piggy back ECU package works out a good deal cheaper than an aftermarket install. For example - To Supply, wire up and Dyno tune an Xede would be around $1650 if SAS were to do it. (After I get finished with all the R&D work with my car anyway and depending where your ECU is mounted)

If you think you want more power than the low 200 - 220 kw mark from your car then I strongly suggest the aftermarket stand alone ECU. The added bonus of an after market ECU is you will get FULL control of the engine, this means the better the system you choose, the better the result and it will take a decent system to provide the level of finese or fine tuning of the factory program. Peak power is not really a concern - everything else is.

Some of those Microtech prices seem a tad high tho. I'll try give them a call tomorrow and get a price on the 1G microtech and Ignition package (They do one specifically for the 1G) if you like. If it was $1500 you would never bother as an Autronic SMC in Non Autotune is close to that to Toymods Members. (Toymodders get Trade at SAS)

Now before you make your final decision on what to get management wise you have a much bigger issue - You NEED to pick your dyno tuner. There is no point considering a package or product your tuner can't tune and not all workshops have the experience or abilty you will need.

I hope that Helps.

Anyone had any experience with Autronic?
