l28et fuel and ecu
Well my l28et is nearing completion here's what I'm running
T3/t4 turbo External wastegate Walbro 255 fuel pump 3inch down pipe Fidanza aluminum flywheel /exedy stage 2 4puck clutch 240sx 60mm tb , I am also wondering about the afm delete/gutting -my goal is 300hp I am now wanting to upgrade the ecu and fuel Injectors , I am alittle foggy on the aftermarket ecus I've heard a lot of megasquirt but I belive there is diffrent types of megasquirt ecu and I was wondering wich would be the best for my set up Also how much hp can I run off the stock injectors safely? I was looking at 7gmte 440cc low impedence injectors , do you think that would do the job? I would like to know what you guys are running to give me a better idea |

Other common options are RX7 460cc injectors, Mercedes 450?cc injectors, Ford SVO 370cc injectors, and Supra 310?cc injectors. Do some searches... injector options for the L28ET has been discussed mucho. :) |
Personally I'd just spend the $50-$60 a piece on a performance injector - who wants to trouble shoot a fuel issue when you're trying to tune your car. You'll need to go with a fuel rail as they are typically all o-ring style.
There isn't a huge price difference between a MS2 and MS3 setup but you'll spend double the difference to upgrade later so I'd say get the MS3 then you've got the expandability and more precise fuel map, etc, etc. I've build quite a few kits for guys - I like the through hole stuff better than surface mount for vibration and stress. The pre built ones are surface mount and lots of guys use them without any problems. Think about 3" exhaust all the way back and porting out the intake manifold as well as an "A" grind cam from a NA head... |
THANKS this helped a lot and i was looking on hybridz Fuel Injector Upgrades/Swap - Fuel Delivery - HybridZ and thats were i got the supra injectors

The AFM is the load sensor. All EFI systems need some type of load sensor. AFM, MAF, MAP, are the 3 main types of load sensors. The Z31T ECU upgrade swaps out the AFM "flap door" sensor for the MAF "hot wire" sensor. I believe MegaSquirt (MS) uses a MAP sensor (manifold absolute pressure).

Read entire page: MegaSquirt: Wiring and Sensors
To answer your question: MAP Sensor The most fundamental measurement MegaSquirt® EFI controller uses to determine the amount of fuel to inject is the manifold absolute pressure. The MegaSquirt® EFI controller uses the MPX4250AP as a MAP sensor, and it is supplied with ALL the units from the current group buy. It will correctly measure from a near vacuum to ~21 psi of boost. It is suitable for all naturally aspirated and most turbocharged engines. If you are going to run more than about 20 lbs of boost, you may need a MAP rated at a higher pressure. Check the 3-bar MAP sensor page for more information. http://atlanticz.ca/zclub/techtips/cam/index.htm |
