Ecotec le5 Turbo 2.4 Build (Page 14/28) wftb JAN 01, 08:19 PM Sounds like you need to talk with alpha fab and see what the tune was supposed to include .Since you bought an all inclusive package , you should only have to do minimum tuning .Did your tuner change the injector constant ?Bigger injectors run like crap at low speeds without changing the constant value . fieroguru JAN 01, 09:34 PM If they started with a factory ecm & tune for your engine, then the cold start parameters should be fairly close unless they swapped in an aggressive camshaft or don't have accurate injector flow rate information (assuming you are using larger injectors than stock) . WOT and part throttle/closed loop tuning happens in other tables, so it shouldn't impact cold start performance. 4thfiero JAN 02, 01:21 AM Interesting, i know the injectors are different. Larger, so that changes things. Ill speak to alpha fab again and see what the base tune includes and whats different on the engine from factory. 4thfiero JAN 02, 01:25 AM here is a list of everything in my kit....

The injector flow rate for the Siemens 60's is easy to get, but did they get the right dead time numbers? That might impact extreme cold starts. 4thfiero JAN 02, 02:23 PM good question, i'll ask them. 4thfiero JAN 07, 10:56 AM *update* Okay...so the tuning is almost done. That's good news...as for the gauges. The IQ3 is gonna be very pricey with all the sensors and connectors. My tuner says he thinks he can get the factory tach to work with an msd pickup wire for 75 bucks. so thats cool, he's gonna try to figure out the speedo. (If anyone has any idea's how to make the stock speedo work with my engine im all ears) As for adding new gauges (boost, a/f ratio and fuel pressure) I figured out that i can buy a zeitronix ZT-2 wideband controller, and hook that into my Magden M.1b computer in my car and display those gauges via my lcd screen. And i can even get additional sensors with the ZT-2 to replace my stock oil pressure and volt gauge and add those to my magden as well (since my lcd screen is going to be mounted where the stock oil p and volt goes. So thats where we are now. Below is a couple pics of the magden computer box and the box displaying over an lcd screen in a car. I bought the same LCD screen for my car. Just to give u guys an idea of what it'll look like. As well as the ZT-2 wideband. http://www.stangnet.com/ima.../2008/10/m1b/M1b.jpg http://www.mp3car.com/attac...tware-picture-12.jpg http://www.zeitronix.com/Products/zt2/zt2.shtml jediperk JAN 07, 06:09 PM quote Originally posted by 4thfiero: *update* he's gonna try to figure out the speedo.
