Pinto 2lt Std N/A Here is the 2D map I extracted using a timing light from the distributor. It's a vacuum advance dizzy but the vacuum was never connected due to the twin carbs. As you can see there's room for improvement as full advance is coming in way to late and the idle advance is too low for twin carbs.
Pinto 1.8/2lt Std here Here is the 2D map I created using information gathered from books and the web. The difference noticed with this map is huge compared to the above dizzy one. The engine now has much more pull through the mid range and quicker pickup thanks to the 14 degrees idle advance.
Pinto 1.8/2lt Std here 3D map created from an Emerald base map for standard 1.8/2lt Pintos running up to 6000rpm. This is the map I am currently using and works fine for me. There might be some improvements to be made as it looks to be lacking in advance at partial throttle openings which would help with fuel consumption.
Pinto 1.8/2lt Std here 3D map created from an Emerald base map for standard 1.8/2lt Pintos running up to 8000rpm. It is identical to the above map, but allows you to rev to 8000rpm. I have not tested this map. Please let me know if it works for you. Thanks.
Pinto 2lt 171bhp here 3D map created from what I thought was an default Emerald map for 2lt Pintos. It doesn't seem to suit my engine because it's infact for a highly tuned Pinto.
Pinto 2lt 171bhp here Another 3D map I created from an Emerald map for 2lt Pintos with 171bhp. I have not tested this map. Please let me know if it works for you. Thanks.
Zetec 1.8/2lt Std here 2D map I created for Zetecs running on twin carbs using information gathered from books and the web. I've not tested this but a friend has on a 2lt with twin 45 Webers and works ok.
Zetec 1.8/2lt Std here 3D map I created for 1.8/2lt Zetecs running on twin carbs in standard tune. The original map was an Emerald one. As I don't have an Zetec I have not tested this map. Please let me know if it works for you. Thanks.
Zetec 2lt 285 cams here This is a 3D map I created for 2000 Zetecs running with 285 cams. The original map was an Emerald one. As I don't have an 2000 Zetec I have not tested this map. Please let me know if it works for you. Thanks.
Vauxhall 2lt, 8v Std. N/A here PioneerX's 3D map. For full details see his site here.
