Well all I've done is the vacuum lines, and I don't really think that'll do much! is there a kit or something that is recommended for the NA?

Alright gents, so this is whats going on, so I think its too lean all the way up? the afr isn't consistent. Do I need to let it run for a bit before I start making measurements

yeah, that 18.0 is bad. i'd probably want to be seeing numbers around 13.7 for normal driving and lower for hard acceleration. you are going to melt something, if you keep running it that lean.

when you let off the throttle, you will see the numbers climb, that is because the engine is still turning fast, but you aren't on the throttle to give it gas. this is normal.
those numbers above 15 when hitting the throttle are not normal. is the MAF supposed to have an O2 sensor input?

nope! its an abaco, part of the problem is it doesn't pump out enough volts, so I'm going to have to screw out the plastic bolt behind the pedal to stop it from over opening .. so 14s at idle, and 12's at wot,15s on close?

this could be a fuel delivery problem, also. i'd be for checking the fuel pump, per the instructions on clarks garage Clark's Garage Home Page. if that checks out, i'd check the injectors, especially if they sat for that long. if that all checks out, THEN i'd start playing with the tune on the MAF.

edit: i googled it. engine management system. what is it that you think you are going to get out of this, over the stock AFM?

well the MAF is giving me faster revs when it works, and volts as in the MAF isn't giving the same range the AFM. its only like 5 volts and its supposed to give 6 or something. so I could program the EMS to understand the MAF and get a better running car.
The AFM provides a TON of resistance to the system. |

oh, and on deceleration, that number will climb. hard deceleration, going downhill with no throttle, for example, it will probably be 17 or higher.

it is supposed to give six volts, but lindsey racing sold it to work on your 944? i find that confusing.

I got the sensor from Lindsey, I knew it wasn't plug and play, part of the problem is the DME requires Xvolts and the sensor give Yvolts, that difference meaning I can't hit WOT completely. I want to upgrade my fuel system to lindseys rails. the MAF is ment to be used on heavily modded cars. like 951's

yes, but is yours an early DME? maybe it would work with a late DME. IIRC, the early DME is expecting 8V from the AFM. let me research that for a minute.

yes its early, they both require the 'wrong voltage' and the sensor is ment to be set up with a custom DME/EMS
