I want to run a tial bov can i run it on a stock ecu with ecutek? or what do i need to be able to run it

 

The Tial BOV has a large 50mm valve that makes venting metered air to atmosphere on a stock MAF an even larger problem because of just how much air it can discharge. Drivability is not good on the stock ECU but the MAFTpro system is a great option for converting to speed density that will not only allow you to run a vented BOV with no problems but also tune like a madman. Lucas at English Racing has recently gone 11.2 @ 126mph on a stock EVO IX turbo using the MAFTpro for tuning and it is significantly less money than a full standalone. If you'd like to spend even less than that, the standard MAF Translator that uses a GM MAF sensor in the UICP above the BOV will let you use your Tial with no problems and offer fuel tuning right on the box. It's not super advanced, but does eliminate the stock MAF for better flow and will make your EVO run like stock with a VTA BOV. If I can help answer any questions about any of these options just let me know!

yea whats the MAFTpro System?

 

Are you planning on going with a larger turbo in the near future? I've read that the Tial is too much BOV for a stock based turbo.

I have the GM MAF setup with a vented Forge DV. It works great and the drive ability was greatly improved with my larger injectors.

 

A IX metal BOV is better suited to your stock turbo...

As Tom stated, the Tial is a VTA, which shouldn't be run without a speed-density or blow-through MAF setup.

The MAFT Pro is Mass Air Flow Translator Pro... it can be used in conjuction with a GM Blow-Through MAF that goes in your upper IC pipe after the BOV (allowing VTA) or it can be used in conjunction with a MAP sensor and an IAT sensor to tune on speed-density, with no MAF.

It's a $500+ configuration, and requires custom tuning. The regular MAFT does not offer speed density, but would allow the use of a GM MAF.

 

TiAL now has a recirculating BOV, but it's not a 'drop in'.

 

nothing but respect for you tom but im on stock ecu and i have a tial in my evo. bought VTECH8R's br upper pipe with tial, his aem ems and a few other things from him and they'd been laying in my room till my green came in. originally i had another pipe with a recirc'd forge dv but after finding out a bracket on the car literally ate through my intercooler pipe, i was forced to put it on prematurely. i'd read about everyones issues with running vta on stock ecu but i didnt really have a choice. he gave me 3 springs with the tial when i got it and my friend put the stiffest one of the bunch inside and told me not to worry about the driveability issues or idle stumbling or any of that because the spring was so hard that it took 2 people to put in and that i shouldnt worry because it was so stiff that no way in hell it'd even open up at idle. its been in my car 2 months now with not a single problem. the last time i went to the track i ran a 12.3 @ 110. with a 1.73 60 and the day after finding the leak i went to the track, bogged from having too much air in my tires and still ran a 12.1 @ 114. anyhow the tial runs fine other than in between shifts, it runs rich. some friends of mine have noted that i now shoot and full on hold fireballs out of my exhaust for a good 5-10 seconds straight that are and i quote "the size of me in the fetal position" . damnit i want my green lol

 

far from drop in

but fear not, we have something else cooking as we speak

 

I run a Tial bov on a stock ecu with a 20g turbo cams and full bolt ons. I have never had a problem with drive ability. At time When i shift the a/f ratio will go to 16 17 then go back to the normal 14.7-14.9.

 

Couldn't have said it better!

I'm not saying that it can't be done, but on the stock MAF cars we've run with the Tial VTA BOV, drivability has not been acceptable. If you guys are able to make it work, more power to you! I'd still definitely recommend their recirc version

if you want to run it on the stock ecu just be sure to buy their stiffest spring and drivability wont be an issue. now the rich factor between shifts is, of course, another story but no biggy imo

 

no i will have a 2.4 block with a race head imight have the stock evo 8 turbo for a bit til i get money for the turbo so i shouldnt try to run it???

 

vta has been fine on most 9's that i know .... 8's is a no go how because i have the same bov from 8 to my 9 ran it at the track too vta and routed back into the intake ... same times

 

i have an 8 mr. 12.1 @ 114 with a bog on pump, stock turbo, and stock ecu and 6speed. runs fine on my 8

 

some tuners say that can tune it where it could run right
