Ok when I get home at 5 ill set them to stock and let you know Sent from my SCH-R530X using Tapatalk

What info do you need? I have not mess with the tune besides change injector size engine size rev limiter shutoff egr and thermactor bye pass and took fuel out to get afr down at wot it ran perfectly fine the one day up and died would not start anything changed distributor and fixed ran fan for couple hours then the coil went bad changed it and ever since then it went down hill tps is brand new iac is brand new with iac and maf plugged in you have to give it quarter throttle to start up and keep it iddleing then it takes part throttle but no full throttle unplug iac leave maf plugged up starts and iddles by itself takes wot but everytime at part throttle its like you shut the key off.... now if you plug iac in and unplug the maf sensor it starts i dles and run fine takes part throttle and wot throttle witch makes no since to me Sent from my SCH-R530X using Tapatalk

So you dont think the maf is bad its just in the tune? I just dont get why it won't run right with my maf plugged in but it runs fine besides some ritchnes and leanness with it unplugged.. I thought it should be the complete opposite.. and that would be awesome if you could do that Sent from my SCH-R530X using Tapatalk

Im on 7-12 thry work and aint had time to hook laptop up or check voltage or mapping on the maf but I should be able to today Sent from my SCH-R530X using Tapatalk

I can't use my software to tweak the curves and tables to get enough out of it And get it dialed in? Sent from my SCH-R530X using Tapatalk

Thanks SniveTroll ill check into that... what I think is going on is the maf is bad and when you give it throttle it reads throttle position but the maf aint reading any air and it shuts the injectors off witch in return is why it won't take part throttle ill check maf sensor tomorrow and if its bad ill just buy a stock one and tune it using my software Sent from my SCH-R530X using Tapatalk

Yes its all dialed in around maf but I'm trying to tune it but dont make sense why you can't have that maf and the iac plugged I its either one or the other but dont run unless its unplugged then runs fine I'm think the maf is bad but I'm not sure Sent from my SCH-R530X using Tapatalk

Dss306 short block pro comp 190cc 2.02 1.60 valves upgraded valve springs upper and lower edelbrock performer rpm 2 intake ford motor sports 24 pound injectors matching pro m mass air flow sensor custom ground still billet cam thru dss dont remember specs its around 570 lift mid 220 on 112 Lsa advanced 4° all 70 mm bbk throttle body cai tuning with moates quarterhorse be and eec analyzer anything else need to know when maf is plugged in the car will not start unless you unplug iac valve(new) unplug it and it starts just fine but won't take part throttle will take full throttle.... plug the iac in and unplug maf the car starts runs and takes part throttle and full throttle just real lean at iddle and rich at wot.... tps is brand new and see it at .98-.99 volts what else you need to know Sent from my SCH-R530X using Tapatalk

Yes i did it is .98-.99 volts now and its brand new and like 4.60 at open throttle Sent from my SCH-R530X using Tapatalk

How many use it and feed back on quarterhorse with be and eec Sent from my SCH-R530X using Tapatalk

Its a pro m mass air flow so could I just send it to pro m and he it recalibrate would that work or is it a tuning issue if so tuning the mass air is bout the only thing I have not messed with haven't had the software long but I love it just need to figure a little more out on it Sent from my SCH-R530X using Tapatalk

Tps sensor I just set to .98 volts and the maf what should it be at and I can check it just like the tps? Sent from my SCH-R530X using Tapatalk

If the maf sensor is plugged in and the iac is plugged in also it will not start or idle unless you give it throttle when it starts you have to keep it idle up or it will die but it will take part throttle then.... unplug iac valve starts up perfectly and will take pot throttle with out killing its seal but then won't take full throttle... hears the kicker plug in the iac and then unplug maf sensor and the csr runs perfectly fine besides it will run so lean it pegs my afr gauge at 21.8 Sent from my SCH-R530X using Tapatalk Iac tps engine coolant temp sensor all brand new Sent from my SCH-R530X using Tapatalk

The car is a 94 mustang gt Is this a tuning issues or is this a bad mass air flow sensor its a pro m calibrated 24# an hour I've got thw software to tune it..it runs unplugged but plug it in and it wont run very good plus it messeswith with the iac valve and have to unplug it to run the iac is new Sent from my SCH-R530X using Tapatalk
