randy Posted July 7, 2002 Share Posted July 7, 2002 Does one need a fuel computer if running boost of 1.2/1.3 bar boost? If so which aftermarket ECU's are available with fuel maps to about 2bars boost? Preprogrammed ECU's. Senario 1- Considering you run a single turbo with 720cc injectors will the aftermarket fuel map be able to handle fueling for single turbo with large injectors. and Senario 2 -Could it also be used with say a stock turbo with stock injectors running 1.3/1.4 bar boost? Will fueling be accurate? Quote Link to comment Share on other sites More sharing options...
Flavio Posted July 7, 2002 Share Posted July 7, 2002 I don't think you need a fuel computer with the stock twins at 1.3bar (1.4bar is already dangerous territory for the stock twins so don't do it). With a single turbo upgrade you are going to lose the stock MAF sensor anyway so you have to have a VPC or a replacement ECU with the appropriate pressure sensors. With the VPC you can control the fuel a bit although most people use a HKS GCC or APEX'i S-AFC with it.

randy Posted July 7, 2002 Author Share Posted July 7, 2002 Thanks Flavio! I dont go anymore than 1.3 bar max! Although I am thinking I would love to have a single turbo conversion. Your car looks great and also must move like a rocket! Quote Link to comment Share on other sites More sharing options...
