Thread: noob tuner - need some help

Hey all,

First question - I'm using a 00 GP GT sedan body with a 00 GTP engine/trans...
Everytime I scan my wot's for tuning I get a p1260 code, which is the (fuel pump speed control relay). The GT doesn't have this relay in the under-hood fuse/relay panel.
I set the code to "no error reported" but I'm wondering if there is a way to keep the fuel pump in high speed? I don't know where/if there is even a relay for the speed
control on the GT body... any advice here is greatly appreciated.

Second question - while scanning wot's, my maf table get wacky! I'm trying to get into mid 11's afr on the 7k rpm and higher cells but when I adjust the table it stays in
13-14 afr... no matter what I do! Could this be a fueling issue?

My mods are:
rebuilt and bored block, 3.0 pulley, heads, headers, XP cam, CAI, ported blower/TB/Lim.

Thanks in advance

Edit: Just ordered a Racetronix Hi-flow venturi fuel pump.
Edit #2: afr gets into mid 11's after about 8250k cell.

Can you upload tune files on this forum? If so, upload your current tune.

Will do. Entire file or images?

On the code. No error reported and no check mark. Your pump is always in high speed being a GT

I didn't realize you were a GT. That's why the code was kicking. It definately wasn't the pulley

My bad bill. Thought I specified a GT model :/

Do you think I should do injectors with the 3.0. I can't seem to get enough fuel during wot scans. I will post pics when I get home.

Well are your injectors going static?

Like running over 100%?

The max I've seen them during WOT was 88%

This is a part I don't understand, I am still kinda new to tuning, but I am unsure which way you are going at this.

I just left the MAF table 100% stock past 7,000hz and changed my commanded afr to 11.5 and got rid of any adders that would change it. I set PE to 35% re did the timing tables to 16* for the last 3 "cells". Thats just a cut and dry of what I did, there is alot more to it.

I was following "starting hp tuners" thread by "theothernick". It primarily focuses on 7k cells and above. Would you be able to send me your tune file so I can look at it? What are your current mods?

Post the whole file.

Haven't changed much. Only idle, fans and maf. Still stuck trying to figure out the maf. I'm upping from a 3.0 to 3.4 and putting in a racetronix fuel pump tomorrow. We'll see if that makes a difference.

I watch the tps all the time. As far as commanded AFR, you mean make a histogram or is one already made?

I have PE set to 30% across the board btw.

Commanded AFR is the "Base AFR vs ECT".

Thanks ffdp.

I coulda gone farther in detail, but thats where you will set the number you want and change a few other tables to get it around that.

More detail is always welcome

Scan this. You probably only have the option to scan one of the PID's.
