streetrover Posted October 3, 2013 Share Posted October 3, 2013 Hello! I've wedged a 4.0 litre engine out of a 1996 Range Rover into my project 914 Porsche. I'm running a megasquirt ECU and need to know the flow rate of my injectors to calculate the Required Fuel setting. I found the chart shown below but it doesn't include my model of injector. Does anyone know similar specs for my part # injector (D18306A)? Thanks, Bob Quote Link to comment Share on other sites More sharing options...
Hybrid_From_Hell Posted October 3, 2013 Share Posted October 3, 2013 I think you are far far far too much worrying and over analyising ..... Think of required fuel as how big a bucket you have and fuel filling it ........ .......and the VE table as the hole in the base to the engine... 4.0 Injectors are the same in all hotwires thats 3.0, 4.0, 4.2, 4.6 etc except THOR Fuel pressure circa 35 PSI via std PRV unit is fine Req Fuel is only approx, MLV or tuner studio it and it will sort itself out As a guide go 20 and 5 Nige Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted October 3, 2013 Share Posted October 3, 2013 Yup, start with 18-20 and see if it fires, then do the tuning and don't ever touch it again. I think the official figure is 18.3 lb, but it really won't matter. Quote Link to comment Share on other sites More sharing options...
streetrover Posted October 3, 2013 Author Share Posted October 3, 2013 All right then guys...I'm gonna go 20 and move on to other settings. Thanks! Bob Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted October 4, 2013 Share Posted October 4, 2013 If you wanted a 'get you running' MSQ, I am sure Nige could provide you a link.... To give you an idea, I ran a Lexus V8 on a Rover V8 map with NO modification at all, then tuned it. Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted October 4, 2013 Share Posted October 4, 2013 To give an even broader idea - the default Chevy V8 map that arrives in the CPU has started & run everything from lawnmowers upwards... I'm pretty sure 18.13lb/hr is about right, but as Nige says you don't really need to know it to make it run as it's basically used as a constant in the fuel calculations, if it's wrong by X then all that happens is your fuel map numbers end up bigger or smaller by some proportion of X. Rover V8 into a Porsche, that's so wrong it's right! Quote Link to comment Share on other sites More sharing options...
