First tune tips and pointers on 1jz single turbo

Hi everyone,

I've been messing around with my street car for ages now trying to get the v.e. map closer to the ideal smooth and consistent increases across the whole map but it never seems to like what I do. It seems like the 2500-3500rpm region under vacuum always wants more fuel than the rest of vacuum areas.

Could this be a function of inaccurate injector dead times or increased cam overlap or something else I've set up wrong?

The specs are as follows

Stock bottom end 1jz, 260 kelford cams dialled in, raceworks 980-1100cc injectors, borgwarner s257sxe turbo

This is on a haltech ps2000 and aem x series wideband on Aussie 98 pump fuel, e85 someday soon hence the big injectors.

I attached a data log and the ps2000 file(had to add .csv extension to the hs2-113 file for it to upload)

If anyone can give me some pointers on how it's going or how I might improve I'd really appreciate it

Cheers all, Matt
