Re: DIY 5.0.
little update on my car
i bought 8 42 injecters $240 http://i10.ebayimg.com/02/i/02/c5/8d/bb_1_b.JPG and a like new but used 76mm C&L mass air flow air meter sensor. This meter is calibrated for 42 pound injectors using C&L's sampling tube. The meter is very clean, and $79 https://i4.ebayimg.com/03/i/04/75/f1/88_1_b.JPG also · Brand New Walbro 255 LPH Part # GSS340 Kit: 400-812 Internal Fuel Pump (within the tank) brings all you need to upgrade fuel pump, 2 Hose Clamps, Electrical connector hardness, curved hose, and washers. 255 LPH and High Pressure Fuel Pump $85 https://i7.ebayimg.com/02/i/04/10/5c/1e_1_b.JPG also last a Holley Adjustable Fuel Injection Regulator psi 35-65 $40 https://static.summitracing.com/glob...-512-500-1.jpg and a thunder bird ex scroll but thats it |

I don't like the ignition timing with 42# and recal MAF, but whatever - it works. I'd smurf a moates.net adapter in my J3 port and start fiddling, but that's me... www.toohighpsi.com anyone? tweecer can solve that. but for WOT only the timing will be alright. unless you lockthe timing with the spout out, then part throttle it'll never go over what you lock it at. but also cruising it wont advance either and it'll run hoter and use more gas :) |

Re: DIY 5.0.
You determine engine load based on MAF flow - when MAF output is jacked around to make larger injectors run like stock AFR-wise, then the ECU is typically looking at lower-flow lower-load portions of it's mappings where the ECU normally looks during cruise - high ignition advance heaven.

you can buy blowthrough MAFs made for forced induction. there is probably a mil people using them i am probably wrong but as far as i understand it at WOT the timing is just off the dist and it'll advance 16 degrees from where its set at the balancer... witht he spout in 10 + 16 = 26 total timing 5 + 16 = 21 ext... i heard the part throttle timing when he spout is in... would be fully advanced 36+ and would cause problems if youlike to boost part throttle like i do edit: you were talkin about recali MAFS. i never knew of that problem with the recals :0 |
