Ollydykins Posted January 23, 2016 Posted January 23, 2016 Hey Guys, Another question, my zed will rev past 5k in first and second gear 100% of the time, third gear 50/50, and never in 4th, 5th & 6th. I'm not a big car guy (as some of you may already know ). I've recently just changed my oil, oil filter, spark plugs and battery. So i'm guessing its a thermostat/thermometer problem? not telling the edu that the engine is warm so its holding it back? BUT, when i do rev past/hit the 5k revs, it will trip out the ECU, turning my check engine light, my traction control and the usual, and obviously then i have to reset it. but this is becoming a big pain in the ass, as i've got my rev limit to 6k anyway, but sometimes just want to have some fun..... Anybody have any idea's please let me know, as the last thing i want to do is go into a garage with absolutely no idea... Thanks, Olly, P.S, if any of you would like a video to explain things better, please let me know (Y) Quote
Ekona Posted January 23, 2016 Posted January 23, 2016 What codes are you getting from the CEL? My first thought is nothing to do with the stat at all. Rev limit on DE is 6500 btw. Quote
Jetpilot Posted January 23, 2016 Posted January 23, 2016 (edited) So what are the codes when your eml light comes on, that will most likely give you a clue Not quick enough ^^ Edited January 23, 2016 by Jetpilot Quote
Ollydykins Posted January 23, 2016 Author Posted January 23, 2016 The self diagnostic. Test? I'll do it tomorrow and let you both know, Thankyou for the quick replies ! Quote
davey_83 Posted January 23, 2016 Posted January 23, 2016 I'd do an ecu reset and throttle/pedal position resets and see how you get on Quote
Lexx Posted January 23, 2016 Posted January 23, 2016 I'd do an ecu reset and throttle/pedal position resets and see how you get on Read the OP. He already does that every time. He needs to find out what the codes are before clearing them to get an idea of what is going on when it's throwing up the CEL. Quote
Mark@Abbey m/s Posted January 23, 2016 Posted January 23, 2016 Can I ask if the car is running on 6 cylinders, very easy to refit coil wiring in correctly after changing plugs. Either cylinder 3 and 5 on drivers side bank and 4 and 6 on passenger side bank. The looms do have numbers in them from new but these do fade and fall off with heat. So easy to be done worth a double check. Normal limp for these cars is 3000/3500rpm Quote
JetSet Posted January 24, 2016 Posted January 24, 2016 Just a thought, doesn't the Anti Knock detector kick in around 5k revs? Possibly faulty, are you running on 98 RON? BTW, wouldn't worry too much about revving over 5k in 6th gear, that's like 140 mph . Pete Quote
Tricky-Ricky Posted January 24, 2016 Posted January 24, 2016 Unfortunately knock detection only extends to 5K rpm, after that its disabled, so its not going to be that. Quote
JetSet Posted January 24, 2016 Posted January 24, 2016 Unfortunately knock detection only extends to 5K rpm, after that its disabled, so its not going to be that. Maybe its not being disabled then? Pete Quote
Tricky-Ricky Posted January 24, 2016 Posted January 24, 2016 Knock detection doesn't restrict rpm, it just retards the ignition timing a few degrees, I would go for the mixed up coil pack theory, providing the DE doesn't run wasted spark? but it is an odd one, I did wonder if it had something to do with the restricted throttle opening in lower gears, but that shouldn't restrict overall rpm.

Ollydykins Posted January 29, 2016 Author Posted January 29, 2016 Hey guys, right, as typical as it is, I now can't even get it to trip the ecu, it's now changed its mind what to do, so now I can't even do the self diagnostic test? Now it will go past 5k BARELY, with the car juddering and shaking like mad, I've got a video; (Yes I know I crunched my gears 😷😷😱😱) https://vimeo.com/153564981 Thanks again guys for the help, Olly Quote
Ekona Posted January 30, 2016 Posted January 30, 2016 Something's very odd there. What happens if you leave it in second and take it right until the rev limiter cuts in? Given you have Nismo clocks, and the jumping of the needle, I'm thinking electrical here. Quote
Ollydykins Posted January 30, 2016 Author Posted January 30, 2016 i have absolutely no idea! i have finally managed to trip it out (never thought id be happy about that) and managed to do the self diagnostics test (with the blinking) and got some codes. they are: 0035? 1003? Olly Quote
Ollydykins Posted January 30, 2016 Author Posted January 30, 2016 (edited) so we've got; P0335 CKP (Crank Shaft Position) Sensor ​and i can't find one for 1003? can't find one for 1003, the one close is ; P1103 MAP Sensor Heater ?? will try again now. symptoms of p0335; Car shuts off suddenly while driving Tachometer needle jumps around or is jerky Engine Speed dips when letting off gas Poor performance which explains a bit ... Edited January 30, 2016 by Ollydykins Quote
davey_83 Posted January 30, 2016 Posted January 30, 2016 These cars have a maf, not a map sensor so I'd be looking towards the crank sensor. My thinking is that would causing starting issues as the ecu wouldn't know where the pistons were in relation to the cams/valve timing for its spark signal..... Quote
Ollydykins Posted January 31, 2016 Author Posted January 31, 2016 Ok Dave thanks for the help, will change this and post my results! Olly Quote
