Bad signs? (time for rebuild)

[Ricco_04]

Just imagen how much more air you will be getting through that port to the same amount of fuel?

That\'s what I always thought but a friend of mine just cant get his round how little we can do on stock ECU.  He has an MR2 Turbo runs standard ecu with much bigger intercooler, turbo back exhaust, bigger BB turbo\'s. induction kit and raised boost etc.  All this on the stock ECU.  

The only things I can think which makes a difference is injector duty or our silly 1spi fuel cut and to only 1 rotor leaving the other one helpless to det if you overboost.

Stock ECU has to adjust quite a few perameter\'s.  Imagine the different volumes of air from driving on a freezing day to driving on a 28 degree summer\'s day.  Then it also has to take in atmospheric pressure so again there is a difference from driving round the coast to much higher altitudes.

Personally I would always use a PFC (or whatever aftermarket ECU) and have it mapped cause its so much better and you can controll the parameters like fuel cut better.  He just got me thinking of the possabilities (which immediately gave me a headache )

I wouldn\'t know the difference with driving a ported rotary as this is my first RX, it drives smooth enough, idles fine etc

Pip told me it would benefit from an Apexi and he\'d recommend it, but it wasn\'t an immediate thing that \'had\' to be done straight away?

I\'ll be getting one as soon as it\'s run in anyway :Thumbs-up

I was just thinking how did you get it through an MOT with no cat and a Half bridge?

[Ian@TunerUK]

It was MOT\'d before I brought it, I do have a cat in the garage though for MOT day...

Ok, its just there is a debate about Bridged Fd\'s not being able to pass an MOT on Emitions and so it intrested me to know how you did it.

I think the previous owner knew the tester or something, guess I\'ll find out come March!

Update time on this!

By tonight I\'ll have completed over 900 miles for my run-in period so I\'m nearly there now, engine is settling down nicely with no problems. Yesterday I ordered my Apexi ECU so hopefully that\'ll be with me in due course ready for mapping properly :chat

Good to hear fella keep us updated! :Thumbsup!

[Nuk Su Kow]

How much was your apexi fella? where from etc?
 
I\'m paying £380 but Apexi are having problems and i\'m wondering wether it\'ll be easier to pull the payment and go somewhere else.....

[m4drx]

thats why i ended up buying my Hks (which is for sale in the for sale section) but if i buy an apexi im sure i will get one from here somewhere i think.

otherwise its HKS ALL THE WAY!

[Nuk Su Kow]

Will your ECU fit a 95 though??
 
if so how much would you be looking for it.....(sorry to original poster, no hijack intended)

[Ian@TunerUK]

I got mine from Nengun, there\'s a bit on their site regarding Apexera declaring bankrupcey, but products are still being made and there\'s plenty of support to be had from the American side etc

[Nuk Su Kow]

I heard the exact same thing.......mine is "supposedly" coming from Japan straight from Apexi but now the delivery date has been moved back till the end of february.....longer than the 2 weeks originally promised!! :reallymad

[The_Tiger]
