alyolles Posted February 17, 2015 Author Share Posted February 17, 2015 Ah, thank you. Never herd that before. Yes I will be "bypassing" the solenoid asap and getting a tune asap as well. Link to comment Share on other sites More sharing options...
cryo Posted February 17, 2015 Share Posted February 17, 2015 Hello there, What everyone has posted here pretty much hit the nail on the head. The vf52 will hit higher boost levels *most times* with the same amount of wastegate duty cycle as the vf40. The car can be driven just fine on the stage 1 cobb map but any heavy boost *ie 50-60% throttle * will cause you issues so it should be considered a "limp" map till you get a true calibration. The hose coming off the wastegate could definitely cause you issues here since it will never send a reference to the wastegate. I would loop the wastegate to limit boost to 8psi or so until you have the option to get the car calibrated properly. Thanks and glad to see the forum shedding all the proper info for you, this place is a great resource.

alyolles Posted February 17, 2015 Author Share Posted February 17, 2015 Thank you very much Dave and everybody that has been helping with this problem. PS. Dave, I will be getting in contact with you very soon to purchase an e tune. Link to comment Share on other sites More sharing options...

The_Paynter Posted February 17, 2015 Share Posted February 17, 2015 OP is a college kid. Not gonna happen. Car is also an AT -- it's in boost almost all the time whether you want it to be or not. We've already well established that the 52 needs a custom tune on these cars. Ah, didn't realise it was a 5EAT. Yeah they are pretty much always in boost haha. Also lead foot syndrome doesn't help Definitely get a protune on that asap Link to comment Share on other sites More sharing options...
alyolles Posted February 23, 2015 Author Share Posted February 23, 2015 Quick question guys, I will be looping the wastegate this weekend and then in about another two weeks will get an e tune. Right now it's running Cobb stage 1 91 map, is it worth getting a lwg map from Cobb until the e tune or since I'm bypassing the EBCS will it not matter?

Edit - why do you have a vf52 with the stock downpipe (it's not gutted right?) My OBXT build Link to comment Share on other sites More sharing options...
alyolles Posted February 23, 2015 Author Share Posted February 23, 2015 Bought the car like that and after all fixes, like a new short block, no money for one yet. Do you know if Dave will tune it with a stock DP? Link to comment Share on other sites More sharing options...

Do you know if Dave will tune it with a stock DP? I don't know why you would want to tune it with a stock downpipe and a vf52. If you had all the money to buy a new shortblock and the vf52 I would certainly hope you could find the $200 it would cost to get a CNT catless DP or any others of the sorts. The stock downpipe with the plated wastegate side and the super restrictive cats will not make the tune worth it. 2005 Vader Wagon Material Tests on Ringland Failure Piston I should have held off and purchased a wagon instead of the spec.B Link to comment Share on other sites More sharing options...

Right now, im not looking for power in the tune, all i need is reliability from it and as long as it runs reliably, I dont mind having to get it retuned in the future when i get a DP.

alyolles Posted February 25, 2015 Author Share Posted February 25, 2015 Guys it turns out I do have an aftermarket divorced wastegate downpipe. Until it gets tuned in two weeks should i use the stage 2 91 ots tune instead of the stage 1? Which will be safer until it is tuned? Link to comment Share on other sites More sharing options...
iNVAR Posted February 26, 2015 Share Posted February 26, 2015 NO. Until you get tuned, you should loop the wastegate line to the compressor and bypass electronic boost control entirely. You do not have the right hardware for any of the OTS maps! Link to comment Share on other sites More sharing options...
alyolles Posted February 26, 2015 Author Share Posted February 26, 2015 I will be looping the wastegate this weekend and it will not be driven until then. Im asking if I should go to the stage 2 map because i do have an aftermarket downpipe. Link to comment Share on other sites More sharing options...
magnusonsubie Posted February 26, 2015 Share Posted February 26, 2015 The "stage" definitions mainly refer to how much boost you are running. Therefore if you loop the wastegate and take the ECU out of controlling the boost you will not hit peak boost pressures that the Ecu would want to see. You may run extremely rich until tuned but simply having a DP is not a reason to flash the stage 2 map. Run the stage 1 map until you get that car protuned. And DO NOT DRIVE THE CAR ANYMORE THEN JUST GOING TO THE TUNERS! 2005 Vader Wagon Material Tests on Ringland Failure Piston I should have held off and purchased a wagon instead of the spec.B Link to comment Share on other sites More sharing options...
