CasperGTI Posted May 7, 2011 Report Share Posted May 7, 2011 The engine doesn't have a MAF does it? Atleast in the Lupo it doesn't.The lupo uses MAP, with temperature/pressure compensation. Ive not herd of this being used before, So good luck if you can get it to work. It seems like quite a bit of kit used on a lot of jap cars.John Quote Link to comment Share on other sites More sharing options...
Heyaxe Posted May 7, 2011 Author Report Share Posted May 7, 2011 Well the SAFC has a air flow in and and flow out can can be wired into the air flow wire on the ecu loom. I don't suppose you have the wiring diagram for the ecu do you? I am mainly after knowing which wires i need to tap into for:Power to the unitRPM SignalThrottle SignalBrown ground wireBlack ground wireAnd air flow wire Quote Link to comment Share on other sites More sharing options...
CasperGTI Posted May 7, 2011 Report Share Posted May 7, 2011 There is no airflow wire.... Like i said the lupo AUB engine don't use MAF, im pretty sure the BBZ doesn't either. Quote Link to comment Share on other sites More sharing options...
Hipwell Posted May 8, 2011 Report Share Posted May 8, 2011 ive read somewhere that you can use one from a Pug as they use the same brand of ECU, but they are mapped for faster engines? If it was on the internet, it must be true. Quote Link to comment Share on other sites More sharing options...
Heyaxe Posted May 9, 2011 Author Report Share Posted May 9, 2011 If it was on the internet, it must be true.Yeah thanks for your very useful input i'll consider that for future reference. Quote Link to comment Share on other sites More sharing options...
Tigzâ„¢ Posted May 9, 2011 Report Share Posted May 9, 2011 Yeah thanks for your very useful input i'll consider that for future reference.I looked into it, you could do it. Just not very well - really really poorly. Quote Link to comment Share on other sites More sharing options...
Heyaxe Posted May 12, 2011 Author Report Share Posted May 12, 2011 Hi again,For those who have done the conversion (Caspter, Tigz esp.):> Are you using the standard injectors (and what size are the standard injectors?), or will the standard injectors make the mix to lean?> I have the 100bhp model, what sort of estimates in terms of torque and horse power would i see from using Jenvys 40mm and possibly larger injectors?> What should i look out for when possibly looking at a cable throttle? I will not be using a standalone ecu but rather a map piggyback device. (My engine does not use MAF).Thanks for your time,Peter.P.S. I will hopefully get the manifold end of this month if i have enough! Quote Link to comment Share on other sites More sharing options...
CasperGTI Posted May 13, 2011 Report Share Posted May 13, 2011 I would get a set of GTi injectors, they will be more than enough for your application. I use 480cc ones but you wont need anything as big.With regards to power/torque... Its all down to how its mapped, if done well id think a 30bhp increase would be a good number to start. As for the torque, that will mainly be done to your setup looking at the butterfly to valve centre length, Trumpet length and overall length.A set of 42mm TB's with GTi injectors, more than adequate for this engine.I don't know how you will get round the cable throttle issue, as i don't know if you can tell your ecu even with a piggyback device that the electronic pedal is not being used. This was one issue i couldn't sort out when trying to stay on the oem ecu, hence why im using standalone. You will be able to fit it and use the TPS on the throttle bodies, but i don't know if it will work. John Quote Link to comment Share on other sites More sharing options...
