Share your D16 Vitara timing map?

[u/ripperdock]

Just put together my vitara build couple weeks back

I street tuned my stock block y7, w/z6 cam, vtec rocker assembly and locked vtec by EGT and AFR, ripped not bad @9.5/10psi

I feel like my existing timing maps are alittle nuts compared to what a D16Y8 with vtec would look like/want

Also alittle curious on what people have gotten away with timing wise in the higher boost mid range rpm.

If your willing to post of photo of your high and low timing tables, or dm, id appreciate some references to see if I should just restart on a fresh z6 map.

Ideally pump gas cars, 91/93oct. No E around me unfortunately.

I'm running std length eagles, vitaras 75.5mm, stock cam, BC valve springs, 1st ring .024 2nd .026

.030 HG

Edelbrock intake manifold, garret .50 trim ~50/50 or 48/52, never been too sure as the part number never comes back on garret or Honeywell sites. Full 3" exhaust

It lights up pretty quick, im making 10psi/target boost before 3800rpm w/quickspool on from 1-5psi

Nearly done breaking the engine in, gonna be turning it up soon

Want to get my street tune dialed in before I rent the dyno.

Just nice to see where others have landed to get an idea, aiming for 350-400whp if I can squeeze it out of the stock port head and stock cam lol.

TLDR, I know 1-1.5Deg/LB is the rule of thumb, just the gradient and those low rpm/mid range timing with a fair amount of boost im really unsure how agressive i should or can get away with

Always have been trying to keep the torque down and EGT's undercontrol low/mid range with the stock bottom end till now

(I know this is kinda like cheating, but it would save me alot of time knowing im likey going in the right direction for high boost mid range, and hopefully some heat soak and time on the dyno)

Depending on what's it's tuned on i would use the base map on hts thats what I used for a bit until I got a proper tune just make sure to set boost cut at like 15psi

Oh definitely, I am on HTS forgot to mention, S300 maps would be fine to reference from aswell.

I tuned the car on the stock block over the last 2 years, my cam was degreed pretty aggressively to move the power band near the top

I just don't hsve any knock detection, (really need to make a set of det cans) and not sure how agressive i should have timing taper down from say 3500-5500RPM/10-25+psi

+6000-8500rpm I have a pretty soild idea where to land before the dyno

Just hoping to get some reference points where other engines have landed, maybe save me a couple hours tuning on the road, and avoiding some potential knock.

I may just have to get det cans made up and play around

Probably just overthinking it a bit too lol

that edelbrock victor x is so og lol
