Hi everyone,

I'm Rolph, your friendly dutchman, driving a JZX100 chaser 1JZGTE VVTi.

Currently working on getting my Apexi Power FC mapped.

Went to the dyno last Friday only to be amazed.

I bought some 570 cc/min injectors, fitted them, Adjusted the PFC injector settings according to the manual (old/new*100%)

But I got some very weird readings on my Innovate LC2 wideband.(very very lean, AFRs of 17-19 odd)

If anyone has some experience, it would be greatly appreciated before I chuck it out the window.

In the attached images I actually ran out of correction-possibility in the attempt to get some decent AFRs in idle.

Did I miss a setting somewhere? (I'm using the black FC-Datalogit box to access the Power FC)

Other spec:


TOMEI m8280 turbo

570 cc/min injectors


Hip 3" downpipe

3" exhaust with 200 CPSI cat.converter

Other than this little mishap... I'm eager to further my understanding of the various systems.

Hi Rolph,

Welcome to HPA.

You might find you get more response asking in the general section for your question. What brand are the injectors and what dead time information came with the.?

Hi Chris,

Supposed Bosch Motorsport injectors (as per invoice)

The red columns are interpolated values, the green columns were provided.

I'll transfer the question to the general section later on, thanks for the advice.
