My Ecu Or Air Flow Meter Shit It Self..

[stormintigers]

hey all, well by my topic heading, you could get the idea that my shitline crapped it self... anywho, its the air flow meter or the ECU...Im getting a mate to put it on a diagnostic tool, to find out the problem and to see if there are any other gremlins...

My question is if its the ECU, am I better of getting a new aftermarket ECU/replace the hole thing, or get a second hand stock ECU/or a new stock ECU and than get a NIStune chip-and plug straight into it???

I have a R34 GT-t tiptronic 98'

I was going to do some upgrades, like:

NIStune

intercooler kit

valve body

Turbotech boost controller

as previously discussed in another topic in here

now also Im thinking of getting a bosch Z32 80mm with a tomei plug after the upgrades that im doing..

ANYway, its about the ECU's, and if it is the aftermarket ones, which one?? or whats good, whats bad, and what to came clean off???

mate for the mods you have listed, i would probably go down the nistune road because its cheaper and easier. if your planning on building a 700hp weapon in the future, then a full aftermarket ecu would be the way to go. see what good tuners are in your area, and see what products they use/tune.

unplug the afm and if it runs (2000 rpm rev limit tho) then there is your problem

you can do this if you ever need to limp the car anywhere

When i took the plug off the afm, the car idled very nicely but as soon as i put down the accelerator it coughed, splatted and stopped... i brought a secondhand afm, hopefully it will come this week, going to put that in, hopefully it works, and than when i get the nistune, im thinking i might get a new Bosch z32 80mm AFM with a tomei plug....

How did you diagnose that it was the ecu or AFM

Well it wasnt me, its was my mate... To cut to short, i told him what happen, he had alittle look, unplugged the AFM plug, and then i started it up, it idled fine, when i rev it alittle bit, it coughed and passed out..lol

then put the AFM back on, started it up, cough, splat, chug chug.

But now, 4 days late after it has just been sittin around the engine light has come on....

Just waitin on AFM.. than ill see where i stand...
