Thanks for your time mate, yes it's dbw, I Spose it is either the throttle pedal assembly damaged, the actual throttle flap/motor sticking or a moody tune, any ideas what cable exactly I would need ?

Ive just connected my car up to a code reader this morning to check the operation of the throttle pedal as it has a live data bit on it, and I found that if I go onto the tps reading and slowly depress the pedal (engine off) all seems fine up until I get to roughly 27 % then any small amount of movement jumps the reading up to either 33% or 36%, I can't get it to read anything inbetween, I am thinking that this is what would make my car Buck , if I'm in that area of travel it will surely be jumping about as I try to hold a steady throttle or am coming on the gas and boost slowly at that point ?

I honestly don't know tbh, would it be better if I went the romraider route, so then I could really get/look into everything, and "maybe" down the line do some tuning, I'm pretty good with the mechanical side of things, just got a bit overwhelmed reading up on wgdc's, injector latency, pedal v requested torque or some such things etc, I'm a born fiddler so once I understand it I'm sure I will love it, just not sure what cable I would need, what laptop ? Software etc

Hi mate

I have put a couple of posts up in the Subaru Impreza forum, hope that's the right place

Hi all, thought I best start another thread for this. Basically I just need to know exactly what I need to log my car 2007 hawkeye wrx, I have no idea even though I have read and read about it all as I'm reading that there's all sorts of different cables etc, I also have absolutely no idea what the logs are going to mean so am hoping someone could read them and tell me if they are good or not, Im hoping it may show why I get bucking in my car (as per my other thread) Many thanks again in advance for any help

Afternoon all, I have a 2007 wrx wagon that pretty much drives good, randomly I will get a bucking as boost starts to come in, it's pretty savage sometimes, enough to throw you about in the seat, it is random and only happens in 1st and second mostly and the boost gauge will jump up to 10-12 psi and back to zero when doing it, the afr will also jump around but I presume that is to be expected, at any other time the afr is good, a steady 14.7 - 14.8 while of boost, going to 10.4- 10.5 at wot with a good taper from the start of boost, I honestly think it could be a dbw throttle pedal issue as when I bought the car the pedal stop was missing from the floor, unbeknown to me, I found it in the glove compartment when I got the car but had no idea what it was until a few weeks later, have no idea how long it had been off or why, but I had mashed the pedal down a fair few times myself without it on , I then read that not having that stop could damage the pedal sensor/casing and to be honest it looks a bit bowed in places, just wondering if anyone else has heard or had this sort of problem Thanks in advance for any help guys/gals, I'm going to post onother thread about logging the car also

Cheers guys, I will probs end up posting in the wrong place as I've taken a few knocks to the head over the years

Hello mate, just joined myself so it's a hello from me, if you could reply to my newbie post, we may just get things rolling

Mornin all, just a quick hello, got myself a 07 wrx wagon after a deer wrote my 03 wagon off, all is good apart from some bucking as it comes on boost, so I'm hoping I can find a helping hand at some point :)
