19's to 24's...... January 18, 2010, 06:33:14 PM What is involved in going from 19# injectors to 24# injectors.I have the injectors,but would I need an aftermarket MAF?Would my A9P work with the new injectors and an aftermarket MAF? Any info would be great. Quote Selected
19's to 24's...... Reply #1 – January 18, 2010, 07:16:30 PM it would be a waste of time and gas putting 24's on your motor. get a good tune, and you'll have better results and fuel economy. Quote Selected
19's to 24's...... Reply #2 – January 18, 2010, 08:03:51 PM Uuuuuuuuuuuuuuuuum ok.Anyhow, at your level vin,24s are a good upgrade,19s were barley enough for the stock HO.You will need a new aftermarket maf for the 24s or the one from a 93 cobra as they came factory with them,(guess ford was wrong on that one too lol).Your A9P will work fine,mine does with my setup.The aftermarket Maf will take care of the transfer function.Guess i should have went with a tune and kept the 19s on mine to LOL.

And a 93 cobra MAF isn't going to work with an A9P. those meters are specifically cal'd to a 93 cobra ECM. Quote Selected
19's to 24's...... Reply #4 – January 18, 2010, 10:33:49 PM Dude it's not stock,he's got highly ported E7's E303 and explorer intakes not to mention headers and exaust,in other word's HCI or dam close to a cobra Motor.The maf will work,i've seen it done,hell TC50 ran a cobra comp with 19s and it made no difference.Not only that the 19s were barley enough for the stock HO.Listen to who ya want vin but you know my experience in the matter.

19's to 24's...... Reply #5 – January 19, 2010, 12:16:23 AM He'll need more pump before anything. You have a PM Vin. Quote Selected
19's to 24's...... Reply #6 – January 19, 2010, 07:52:57 AM That is true however, i think he has a 155lph Quote Selected
19's to 24's...... Reply #7 – January 19, 2010, 08:50:47 AM Hey Vin-I basically have the same setup as you do(E303,24 lbs,exhaust,93 cobra mass air,155 pump) I have an A9P and it works fine. I gotta be honest I did all of those mods at the same time and I felt absolutely no difference(seat of the pants). But It sure does sound better. Quote Selected
19's to 24's...... Reply #8 – January 19, 2010, 09:06:05 AM Alright,to clarify.....These are for the new engine....GT40-P engine with worked heads (ported,valve job,etc),Trick Flow Stage 1 cam,Explorer intake,65mm t-body. I do have a 155 lph fuel pump in the tank now. I'm trying to get everything ready for the new engine when it goes in.The 19's on my current engine will stay on the current engine.I think that the 19's on the new engine won't be enough. I have the injectors,and,I have a Mark VIII Mass Air meter/sensor,BUT,I am planning on getting a C&L meter for 24's.I need to know,if,the C&L meter,and the 24's are all I need with the A9P for my car.Getting a tune for the computer isn't really an option right now.No-one near here does that.Once everything is assembled,and I'm pretty sure I'm done under the hood for a while,a dyno tune will probably happen down in Dallas later in the year,or early next year.

I've never owned a Cobra EEC or MAF... I've mostly run a Pro-M 76mm & 24lb with either a C3W1, A9P or A9L(which I prefer)... Quote Selected
19's to 24's...... Reply #10 – January 19, 2010, 09:18:32 AM I haven't really checked into a Pro-M meter.I will look at them.I had an offer for a C&L for a hundred bucks delivered. Quote Selected
19's to 24's...... Reply #11 – January 19, 2010, 02:26:02 PM I thought you had the eec that started with an x3 or something and it was from a cobra,you said you tried it and it made no difference,hmm guess i was wrong.I did however know the cobra maf would work with the A9P. Quote Selected
19's to 24's...... Reply #12 – January 19, 2010, 03:35:52 PM X3 ECM is 94-95 is it not? Quote Selected
19's to 24's...... Reply #13 – January 19, 2010, 04:31:43 PM I have thought about using the Cobra ECM,BUT,it would cost more than an aftermarket MAF,and,they are actually a little less aggressive than the A9P and A9L.I'll just get an aftermarket MAF when the funds are available and go from there.I think the MAF (Pro M,C&L),should make it all good with my current computer.

19's to 24's...... Reply #14 – January 19, 2010, 05:12:03 PM I know I pm'd you, I ran my pro-m with the a9l+p they were the same, I kinda like the p better because rpm stay up longer between shifts. I really don't use the clutch to shift. Quote Selected
