Need help GTR BPT and BOOST
I know the injectors on the BPT GTR are low empedance but what CCs are they. How much boost are they good for. I finally bumped into a GTR ECU and will not be looking at an EMS anymore thank god. I am planning to go with corksports MAP ECU in the future and APEX'I AVC-R for now.

well first off They are 450cc injectors. The GTR ecu is good up to around 18psi. That is as far as the maps on it go. And as far as MAP ECU, I would suggest Greddy Emanage Ultimate. Around the same price, but controlls Spark too, and it has an awesome autotune feature where in conjungtion with a WBo2 sensor you set a target A/F ratio and it auto sets itself. It is awesome.

I think it can be wired into the stock sensor wires at the ECU. However a MAP sensor is more accurate and less resrictive.
The stock injectors will be fine for what the turbo can push (Mazda thought ahead for you on that one )

LOL just updating just remembered where i heard about the low impedance. I got that from derrik at corksport I have to swap out for rx7 450cc high impedance injectors

either that or you could get resistor packs for the GTR injectors. the gtr came with them stock, but you could use any resistor pack made to run low imp injectors on a high imp system.
what are you running for a turbo? remember that the GTR ecu is good to 18 psi on a vj23... which would be the equivalent of WAY more psi on a smaller turbo like a vj20. i dont even know if you could even max out a gtr ecu with a vj20, even if you welded your wastegate shut!

Actually I am going to 5 finger a resistor box from the local junk yard out of a mid 90's Accord, they came stock in those.

Anyways, if you search you can find the writeups on how to wire in a normal MAP sensor into the emanage so you do not have to buy the official one. But I really think that is going to be my next big purchase for my car (I bought the LSD today )

Re: Need help GTR BPT and BOOST
I seriously hope your NOT buying a Map-ecu from corksport as they just lowered there prices on them to 550 when originally they were charging 650 and the funny thing is you can order the Map-ecu direct from the manufacture for only 399. and shipping isnt 150 dollarsMechaManZero wrote:I know the injectors on the BPT GTR are low empedance but what CCs are they.

nope bugs, i was looking for an mx-3 but couldnt find one anywhere. settled for another escort GT. i'm here because i need to buy some parts, and i need to make 30 posts in order to post in the for sale forum! lol. also, its always good to read everyones views and share ideas about BPT setups, since i am building mine soon. i'll be sticking around here i'm sure
