Hi Adamw Yes you are right,forgot to mention the controllers. They both of them have. Zeitronix and Innovate LC1.

Scott Does it make sense to power multiple 12V devices from one single power source? For exapmle you mentioned in the first post that i can feed the ISC solenoid with ''the Ignition switched +12V could be the one used to power the ECU'' Can i for example split the wire in half that goes to +14V to my Vipec in order to power other accesories as well?

Hi there. I am in the process of bulding my harness.I am planning on using 3 oxygen sensors.2 widebands and the OEM narrowband. They will be located as follows. The 2 widebands in exhaust ports 1-4,2-3 and the OEM norrowband just before the cat. The purpose is to keep AFR readings as accurate by splitting the readings in the exhaust ports as mentioned above and the OEM narrowband will be kept on order to help me tune in CLL. I believe that monitoring the AFR target values with one wideband doesn't mean that all the injectors spray the same.Especially under WOT. My questions are 1)Is the narrowband better than a wideband,in means of fuel economy and accuracy being more accurate in the stoich area? My 2 widebands are user programmable.Does this mean that i can make them act just like the OEM narrowband,on not? 2)How can i wire in the 2 Bosch LSU wideband sensors to my i88 Vipec?According to Bosch the pin out is the following. Pin 1 Pump current APE / IP Pin 2 Virtual ground IPN / VM Pin 3 Heater voltage H- / Uh- Pin 4 Heater voltage H+ / Uh+ Pin 5 Trim resistor RT / IA Pin 6 Nernst voltage UN / RE Thanks.

Scott thanks and all the team running for the users. How will I know the following? Quote "Just make sure that the supply you use can handle the additional load."End quote Apart from testing is there any other way to go around?From your experience from where would you take the +12V? Thanks for the Support! Lewis

Hi there. I am bulding my harness for my Mazda Miata 99 model,with an adapter so i am using my exhisitng engine harness in order to terminate it to my Vipec i88,with plugs A and B. I have the ECU pinout but i have some leftovers pins from my ECU that i cannot decide where they should go on the Vipec. 1)First my ISC valve has to wires which are 3M and 3Q pins on my ECU.According to Vipec manual ''Two terminal ISC solenoids need only one auxiliary output (or ignition channel) to open the solenoid. A spring is used to automatically close the solenoid. Connect one terminal to the engine managements power supply and connect the remaining terminal to an Auxiliary/ Ignition Output Output. The orientation of the wires does not matter. An ISC solenoid must be wired to a switched power supply.'' So if i am correct one of them should go to one Aux input and the other to +14V in Vipec plug A.My ''problem'' is that +14V is used in order to feed the Vipec.Are there any other pins in Vipec's plugs that give +12V output?Can i use the Aux +14V 9/10 on the plug B? The leftovers for completing the harness are the following. 2)1A Back up power supply(What is that really?) 3)1H Battery positive voltage monitor 4)1O General field coil control 5)1Q Generator warning light 6)1T Generator 7)3K Fuel tank level Note that the original alternator was controlled by my ECU.I purchased an old type alternator with the regulator build in from an older Mazda Miata. Attached is the ECU pin out. Thanks in advance,any help appreciated. 1999_ECU_diagram.pdf

Hi there. Is there a way to transfer a complete tune from a V88 to my i88 ECU. There is the option of doing this manually but I want to save some time....Off course I will double check everything prior cranking the engine. I have the latest software on my i88,the one from Link site. Thank you guys.

Was the mystery solved?I am planning my own i88 installation.

I am looking for a good used V88 unit. Please packaging,looms,MAP and IAT if present more than welcome.
