Zero Off Conversion

[bojans]

I know this has been talked about before but I cannot find the threads. What does it take to upgrade a 196 to ZO?

2006 - is it possible, if so what does it take

2007 - I know it is possible, but is it any different than 2008 and beyond, what is required'

Any help appreciated as we are currently in the market.

@Jody_Seal ?

About $5-7K if you don't have the correct ECM. Stick to a late 2007 and up and it will be plug n play and about $1500.

Try Tim at Inboard Solutions. I did my 02 in 2010.

@thager I can't find any info on him. The website comes up as a condom club.

06 conversion, 07 plug and play for the most part. Early 07 E-control ECM's may need re flashed / updated from Pleasurecraft marine.

$5-$6K for a conversion of pre 2006 PCM engine's. $3-$4K for a 06.

@Jody_Seal , are your September '17 estimates still about right? Pre-2006 Response?

[Jody_Seal]

Those estimates are still close but also those estimates are based off of converting Pleasurecraft marine engines. maybe some one else can chime in on what it takes for and Indmar Malibu.

Reminder, No mater who marinized the engine as long as the engine is a 96 or newer Vortec chevy 5.7 it can be converted, the pocket book is the only constraint.

@Jody_Seal where would one go to purchase components from econtrols? I've been very curious about it but cannot seem to locate actual vendors selling parts.

[Jody_Seal]

You can only purchase the ZO unit from E-control. The PCM componets can be purchased from either my self , Inboard solutions or a PCM Dealer if you know what you need .

[BraceMaker]

Thoughts on wiring harnesses and TBI throttle bodies?

@BraceMaker

Yea remove it and install a full Excalibur induction system if you want ZO.

But it won't fit a indmar 350 pre 96 non vortec

[Jody_Seal]

Nope, need a crank sensor and vortec heads.

Not saying impossible but defiantly a challenge to convert a pre 96 non vortec engine..

Jody is the ZO conversion KING. Jody converted my 2004 Limited 196 way back in 2009 and it has worked flawlessly since installation. Thanks again Jody!! MWN

As Jody noted, the GM small block cylinder heads changed in 1996 to the Vortecs. The intake manifold to cylinder head bolt pattern changed. You can get parts to fit, there are intake manifolds that carry both or the other bolt pattern to update a pre '96 setup, the cylinder heads are the key element in the ~ 35 hp power bump in that era.

[BraceMaker]

@DW so if one could get a CPS signal and adapt the intake runner about any chevy small block could go ZO.

[DW]

@BraceMaker : In theory, yes. Not sure how the pre Vortec heads would mesh with the ZO calibration, probably okay but the throttle needs would actually be different due to less airflow and different response. As Jody notes, going with the correct heads would make sense, and you can get them from a junkyard these days. I don't know the calibration tables used for ZO, you might want to know how the specific inputs are used in the software before you jump off that bridge as you would need to match those up.

 

People may not remember nor care, the old Accuski system allowed you to write your own calibration map.

@Jody_Seal - has anyone ever converted a Chevy LS1 to Zero off ?
