begi turbo help !!! please!!!

[atticus]

ok got my begi turbo install everything is working ok except one thing after drive in any gear if i put the car in neutral the rpms drop sometime dropping to were the car dies out. now i've calling the tech a flyin maita and begi and they just keep saying the proetge is know for this and have no tech help to fix the prob except for adjusting the fast idle valve on the throttle body. If anyone has any suggestions or help please help

thanks

what kind of RPMS? 600-700 is normal.

does this kit have a BOV or BPV (recirculating bov) ?

that can very well be the problem... if your bov is atmospheric the maf is reading the air that the turbo is throwing at the motor... but it's not getting that air because the bov is just dumping it. so the computer is trying to compensate for more air by dumping more fuel even though the motor is not getting the air because of the bov.

hense... you are flooding your motor with fuel.

my kit has a bpv (i have a custom built kit with some MAM parts).
if this is your problem then you have two options:

1: get a BPV

2: move the BOV so that it is before the MAF (i'm not too sure if this would work, but in theory, it should)

the rpms are dropping to 200 to 300 and as low as 100 or till the car dies out.

I have the recirc bypass that came with the kit from flytin maita.

and still having the prob.

hmmm...

whats controlling your fuel? are you useing an fpr? where are you getting the vacum for the fpr from?

this is a flyin protege kit using all the conponents the kit came with as for the fuel using the begi fpr and the vaccum is comming from the signal soruce the kit came with which is tied into the brake booster vaccum i believe.

do you have the voltage clamp installed

 

[accuser]

if he didn't have the voltage clamp he would be running lean when in boost... and since he bought it from flyin miata... i'm assuming they would have sent it to him... wierd...

well... do you have the voltage clamp... installed?

hehe....

not entirely true. he would run lean under partial boost/partial throttle and it would pull fuel during/after partial boost runs. the voltage clamp, if installed, might also be bad as they tend to fail early and often on the protege whereas they last forever on the miatas. I've run the BEGi kit on my protege5 for over 30,000 miles so any issues you might have with it I can try and help with.

 

[dominoy2k1]

maybe its just a vacuum leak. i dunno.

 

[atticus]

yeas i have a voltage clamp brand new

captain krm p5 have you even ran into this?

can you hear it 'click' on when you go into boost? its not easy to hear, but if you don't hear it then its not working. do you have an air fuel gauge or wideband gauge of any kind telling you your rich/lean conditions? it sounds to me like the ecu is pulling fuel. when i did not have the voltage clamp and i came out of boost to a dead stop or a slow roll my car would stall. the clamp fixed that.

what sized flywheel do you have? the stock one?

 

[atticus]

stock flywheel, can't really hear the clicking sound becuase its under the metal plate and behind the carpet, i have a autometer gauge and when in boost its mainly in the green (rich) something at the last green led on the gauge.

I drove today and it did fine as long as i down shifted from 5th to 4th then depressed the clutch it wouldn't die but if i was running from red light to red light about 100 yards and hard on the throttle like 1st and 2nd it would die.

 

[Captain KRM P5]

i am thinking its the voltage clamp from how you described it. what is your base fuel pressure set to on the FPR? what is the maximum fuel pressure under boost?

 

[atticus]

corky bell said for me to set it at 45 base and the pressure under boost is 65 to 60 psi

 

[Captain KRM P5]

that sounds about right - i always ran 50 psi at base and 70 to 75 psi under full boost

 

[atticus]

ok i think the problem is fixed last nite i took the bpv off the screw on the top was all the way in so i backed it all the way out then moved it in one and a half turns seems to be work got know no drop in rpms or die outs.

thanks for all the info.
