powernut 1 Posted December 22, 2010 Author Report Share Posted December 22, 2010 ps kev alterd the injector msec from 1.000 to 1.5000 and showing 1.7 on gauge and dose idiol better (something that worked lol) Link to post Share on other sites
FishWick 21 Posted December 22, 2010 Report Share Posted December 22, 2010 right bare with mew kev ' date=' more techical stuff im runing 560cc at 4bar in stead of stock 3bar ie 560 at 4bar gives 640cc regards injectors , on the ms screen its showing 1.5 msec?if thats what u meant kev ,still having this reset issiue ive tryed adding noise settings rechecking earths lives and adjusterd vr pots which hasnt helped[/quote']Yeah that's what I meant mate. What injectors are they? Siemens? Have you put the dead time into the MS, if you know it? On the big Siemens it's around 0.86ms @ 14 VAnd are you running batch or sequential injection? I would imagine sequential if the injector ms is that low?Fun this isn't it?! :-) Link to post Share on other sites
powernut 1 Posted December 22, 2010 Author Report Share Posted December 22, 2010 more complex techical stuff , lol right i know these are 3.3 ohms low inpedance but added inline resistor to convert them to high inpedance , i found runing 1.400 msec was the best i could as any less i get hunty idiol and any higher went rich with slight missis so i assume there was too mutch fuel , injectors are from a std evo 0evo ones 560cc ones but at 4bar not 3bar injectors are set to injector open time ms 1.400battery volts ms/v 0.200pwm currernt limit 100pwm time thershold 25.4injector pulse width period 40same applys for bank 2 runing duel fuel maps as ive had major issiues with rear bank with heat soak and det Link to post Share on other sites
powernut 1 Posted December 22, 2010 Author Report Share Posted December 22, 2010 kev just a quicky regards loss of sycro , is ur igintion input capture set to riseing or falling edge? mines set to raiseing edge , woundering if its wrong??? Link to post Share on other sites
FishWick 21 Posted December 23, 2010 Report Share Posted December 23, 2010 Ah you're using low impedance. It doesn't usually work that great using resistors because peak and hold works differently to saturated drive (high impedance) injectors. Although they will run with a resistor, they don't quite run as they should.If I were you mate, I'd flog them and buy some Bosch EV14 550cc http://www.sprayitracing.com/52lb%20Bosch%20EV14%20High%20Impedance.htmI have some myself and they work great and you can run them at 3 bar and get some reasonable pulsewidths at idle, but it depends on your budget I guess.They're standard on some American V8s and Mustangs etc, so could get them cheaply on ebay.You will need some USCAR connectors, or adapter connectors (EV1 to EV14).My DTA doesn't allow you to adjust the ignition capture. Isn't that a distributor function? Are you using a coilpack? And are you using the internal amps or Megasquirt's? Link to post Share on other sites

AJmk2 2 Posted December 23, 2010 Report Share Posted December 23, 2010 Revving to 8000 rpm ? , be interesting to see how long that lasts, rpm load cycling will destroy your rods before power does Why cant you run the injectors as low impendance? Link to post Share on other sites

powernut 1 Posted January 10, 2011 Author Report Share Posted January 10, 2011 hiya kev good to hear from you well , lol ,,ive decided to stay with megasquirt , only couple of main issiuss im having is idiol (i did increase to 1.4 as any higher and runs rich , with mnium numbers in the fuel table , second prob was sycro loss , known as reason 2 , which ive sent the unit off as it needs a u7 socket fitting , other then this it run ,, and idioled ok cold just up and down when up to engine temp 75deg ,i also noticed ive had mat riseing , so just buzzed a quick box on the intake to see if it helps and fitted a open element intake sensor , for better responcequick pic hereas i couldnt add a clyinder type due to room issiuses in a mk1 Link to post Share on other sites
FishWick 21 Posted January 11, 2011 Report Share Posted January 11, 2011 Good stuff mate, sounds like you're getting close then. Good move on the Megasquirt. Motronic is OK and all but I don't like it for boost. That's a hefty plenum box you've knocked up there! Looks great. Link to post Share on other sites
powernut 1 Posted January 11, 2011 Author Report Share Posted January 11, 2011 well im unsure regard megasquirt , as getting tuning somert like is a pain in the ass tbh , sometimes seems ok then goes haywire , something i never had with stock ecu ,, working on the v8 at mo , so ill get to caddy see if the mat are any better Link to post Share on other sites
AJmk2 2 Posted January 13, 2011 Report Share Posted January 13, 2011 Whats the V8 project? If this is anything to go by should be mental!Id personally set a conservative rev limit around 6600. Even if your rods and pistons ect are designed to take the extra load unless your head has had some serious work done to it the valvetrain wont be able to cope. Link to post Share on other sites

FishWick 21 Posted January 13, 2011 Report Share Posted January 13, 2011 V8 Nova, nice one, I like your style! :-)You have definitely got the speed addiction!Are you still using those Evo injectors with resistors mate? It will take a while to get used to the MS and how your engine behaves to the map changes. Took me a while to get to grips with my DTA but because I use the car every day, I soon had a sweet map done :-) That's the only difference between DIY and Professional really - the time it takes to achieve your goal.

powernut 1 Posted January 13, 2011 Author Report Share Posted January 13, 2011 ok for a bit of fun , regards idiol , dam nightmare when i think is steady then suddernly goes loopy again , from cold its fine and instail start from hot its ok , after around 5,6seconds goes loopy again bloody thing , , maping tuning tunieing rest isnt bad ,tbh kev Link to post Share on other sites
FishWick 21 Posted January 14, 2011 Report Share Posted January 14, 2011 It's fine when cold because of the bigger pulse width on the injectors. What AFR does yours hot idle at? 2ms hot idle was too rich wasn't it if I remember, around 13 AF?I don't think the injectors are helping you tbh, but you could try getting the Motronic remapped on the dyno?

powernut 1 Posted January 14, 2011 Author Report Share Posted January 14, 2011 thats makes sense , i didnt know that ,as i can tunie the cold warm up enrichments , from cold no idiol valve at 13./14 afr , as as this switchers off , i carnt get a steady reading (rather jumpy) 13 to 15 afr , ive made sure in igtyion timing/fuel/afr maps thats the 4 boxs that it moves in are all the same , i tryed altering the injector pulse from 1.000 to 1.200 (yet show 1.7 on gauge? i carnt lift it mutch more as its too rich to try tunie out , (if u roughly understand what i mean Link to post Share on other sites
powernut 1 Posted February 4, 2011 Author Report Share Posted February 4, 2011 runing ok ,so going to fit the megasquirt ms3x (was cheep thought id try make a downpipe , what a task in a mk1 golf with 6sped transforbox and propshaft plus steering rack in the way lol couple of quick picsim wishing id done a mk2 golf now as there lots of room just need to heat wrap the buggar next when it arrives Link to post Share on other sites
