ben_harmer32 Posted August 14, 2019 Share Posted August 14, 2019 I've been getting error code 34 coming up when boosting the car (not all the time). Checked all VSV and vac lines and all seem good. The car has a boost controller fitted but it is not on. I went to my friends and using his Supra as a guide put all the vac lines back to stock and removed the solenoid for the boost controller. Still have the same issue. So decided to check the ECU and discovered my car doesn't have an FCD fitted (despite having a receipt for the part and for the fitting from the previous owner). I speak to him regularly and he was as shocked as me. I'm guessing/hoping the error code 34 is down to the stock boost cut? (Happens at around 15.8 psi which is essentially just over 1 bar) Car has double decat and a restrictor ring fitted. Does this sound about right? Should the car be running that much boost using the stock VSV's just from having decats? Thanks in advance! Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted August 14, 2019 Share Posted August 14, 2019 Normally you get a code 14 (ignition) if you've hit boost cut, not familiar with 34 Quote Link to comment Share on other sites More sharing options...

ben_harmer32 Posted August 15, 2019 Author Share Posted August 15, 2019 Thank you. Found this in one of the threads Well that error code means you are overboosting as far as the ECU is concerned, you'll get it logged every time you hit fuel cut. If you reset the ECU and drive so you go on boost but don't go over say 0.8bar then check the codes again, you'll probably find the error isn't there. Hit 1.2bar then and recheck and it'll probably be back. -Ian Quote Link to comment Share on other sites More sharing options...
ben_harmer32 Posted August 15, 2019 Author Share Posted August 15, 2019 (edited) Hoping I found the issue. Plug to the waste gate vsv had a broken wire. Could have been barely holding on and fully snapped when I removed the plug causing a dodgy connection? But hopefully that'll resolve it. Will go for a test drive in a bit!
