went for mapping today but had problems?

[thomas_mk6]

hey guys went for mapping at wgt today, the set up is

front mount
double throttle removed
decat and 3" back
japspeed turbo elbow
viton check valves
and turbo simplification mod (vac hoses)

however when it came to mapping it wouldnt budge over 10 psi (i think it was 10 psi) pip was very busy today so we though it was best to take it back home and make the vac system factory again, as he wasnt familiar with the vac simplification mod,

however from the diagrams on rob robinette it shows nothing for the fpr, so i took a vac hose from the lim to it without going through the solanoid, i thought this could have been the problem when getting home and looking at the two diagrams togeather but then i spoke to pip on the phone and he said it shouldnt be a problem

i quite like the ida of the simplification as it makes it easier for a simple minded idiot like me to diagnose problems, but i think i am going to put the rats nest back in this weekend and try again when he has a spot free


does anyone have any ideas?


also seeing as i have removed the double throttle do i just leave the solanoid that controls it unplugged from the vac system?

:wiggle

Do you still have the stock pill in the vac system controlling boost levels ? You may want a profec B spec2 or similar boost controller.

The FPR doesn\'t run off a solenoid (as I remember) its just as boost rises the pressure rises too. Where have you plugged it in. There are a few lines that give a weak signal. Best matching the original standard diagram nipple.

was just about to say, what is controlling the boost, i know nothing of the rats nest tbh and dont want to lol

if that isnt the problem, then im sure others who have done the mod will help out.

[neil_jdmr]

Yep as said abopve you need to check you still have the pills fitted, ( although Im sure even 10psi is unachievable if you have removed them)
 
Also the double throttle solenoid can just be blanked off, i just removed the sol supply hose and blanked it, no probs

[thomas_mk6]

i still have the origional hoses with the pills in down by the turbos, i am using the apexi to control the boost, the problem is the diagram showing the simplified setup uses a california setup so there is an extra nipple at the top of the lim,

its just very confusing to me, i am right in thinking the apexi pfc can control the boost to a certain point?

[neil_jdmr]

Not without the apexi boost control kit which is just an external boost solenoid.
 
You can up the boost on the commander to a point without the above but only by changing the boost duty cycle NOT the boost value as such.

Are you able to select between two boost settings on the commander, if so any ideas how.

cheers

:wiggle

Surely he didnt say that :2eek

[thomas_mk6]

ok then say i wanted to do to 0.85 bar of boost, which i know is fine on standard fuel system, is this possible with just the apexi ecu and commander? i thought it was

[thomas_mk6]

also when putting the rats nest back in, because i have removed the airpump, am i right in thinking i no longer need to plumb in solanoids B and C (on the hose diagram) for "relief 1" ans "switching"?

I\'m sure he did. Pip is a busy guy, so if you turn up for a mapping session and have boost problems, he will tell you to book it in to sort the problem out on another day or sort it out yourself and re-book the mapping session.

I doubt he has time to d1ck around solving a "vac simplification" mod gone wrong when he has a boat load of other cars booked in to map on the same day.

[thomas_mk6]

ye he had another 3 cars to map after mine, and to be fair id rather have a go myself and try and learn something, any ideas on the solanoids guys?

[fil_auto]

Yep - that can be done as that\'s what mine is running - non-sequential mind......

thanks fli auto, my silicone vac hose just turned up so ill be having a bash after work tonight

[thomas_mk6]

right when i got back from work i ripped everything out and started from scratch, i followed the vac diagram and marked off every hose as i went along and i am 100% everything is in the right place, 2 of the solid hoses on my rats nest had snapped so i havnt used it, i have just used t pieces where i needed to, on this edited diagram i have made everything in clear isnt included in my setup because i have removed the airpump and double throttle, also mine isnt california spec so i dont have egr

after i finished i started her up and she idled fine, let her warm up and went round the block, decided to be a naught boy as i am only on a part map as pip only did the low speed stuff, boost pattern was perfect, no problem hitting 10 psi, but then again it did that before!

here is the diagram


the problem is, i dont wanna go back to wgt and have the same problem again, i cant afford to leave the car with pip to tinker with as i can just about afford another mapping session, i need some way of testing it is ok before i go back to have the map finished

any ideas guys?
