Mines ecu and td04 setup

Hello , I just installed a mines ecu on my
Stock 4efte . The car has front mount intercooler ,full exhaust and downpipe , updated fuel pump , carina 2ct turbocharger and equal length manifold running 0.9 bar .
fueling checked with wideband is 10.5 . Has anyone run td04 with mines ecu ?? Could it fuel correctly ?

Yes, I've run one. Just keep an eye on the fueling and listen for det. Would also advise you start with stock boost level then you can dial in more if the AFR allows (likely).

ok , the car runs stock ignition advance 10btdc , I have never heard any det , even at 1 bar of boost with diesel turbo from carina , slightly bigger than ct9 , all the Rpm range the afr is at low 10s
100ron fuel , at 0.8 bar at the dyno the car made 170hp at engine

ar you listening for det with det cans or just by listening to the engine as you drive it? i would be careful just listening whilst driving as it can be hard to hear mild det when the engine is screaming at 7k rpm!

low 10s is far too rich. do you have an adjustable fpr you can turn down to compensate?

no det cans , no stock fpr and stock injectors !!! i think that stock fpr is safer.
these is ecu weren't made to work with stock fpr ? when cruising the afr is perfect 14.3-14.8

I don’t think that det may occur with stock timing 10 degrees btdc and 100ron fuel , I was thinking of a td04 setup to get rid of boosting at low rpm , and have a more agressive top end

Still sounds a bit rich on cruising.

10 degree base timing is fine, but you don't know what timing the ECU is using, so could be quite advanced when on boost.
I'm not sure if the pnp ECUs adjust timing independently of the stock timing tables?

With the power you are running, it doesn't sound like it is running that great. An adjustable fpr will let you turn the pressure down a bit and get you a little leaner. That rich mixture on boost is killing your power.

Yes but I think that this is the safe side , if the ecu is tuned to work with the stock fpr maybe this much rich is good , it’s quite hot here so maybe at winter the mixture will go leaner ??? I notice that at night that the temperatures goes down a bit , the mixture goes leaner about 10.7-10.8 with outside temp 24-25 Celsius the car feels a lot faster !!!

The ECU was probably mapped for a completely different setup to yours. Most people have no idea what it is mapped for so your best bet is to fit it, check it and try and adjust where you can to get it closer to what you need.

At what point do you get 10.5 afr? What rpm?

I'm not sure what your original question was as it doesn't sound like you want to adjust anything?

Revlimit at 7600-7700 , and not the classic one , i think it cuts ignition not fuel it cuts and does a very fast limiting sound , don’t know if this helps , also didn’t know that every ecu was mapped for a different setup , most people at forums say that the ecu fuels every setup at the rich side for safety.

Yea all the Toyota ECUs overfuel slightly for safety :) these types of ECUs use the factory ecu with a daughter board attached for the remap if you like to put it. They where developed with kits specific for them to get the most out if the car.
Nothing to say you can't mix and match tho, just keep an eye in the fuel/air etc
Adjustable fuel pressure regulator would be ideal too, I bought 1 for my wepr kit and tf035

I have yet to fit it, cars of road 3 years now lol
It will be ran with the fuel pressure regulator at 2.5bar and have the fueling checked. JAM fuel cut defender too and run it between .8- 1 bar :)

I have not worked with that ECU before but it obviously needs a tune or get rid of it.
BTW you dont hear knock on most Toyota engines. They overheat and blow head from too much timing.
100ron is good yes. But what is your elevation?

I haven’t any problem yet , I don’t believe that timing is too much , car seems same not much difference , afr is good , I have run 0.9 -1 bar and no problems so far !!!
