Chur chur Mr Dave

Wire the trimmer like a TPS unit, 5V Ground and signal. Feed the signal to a AN Volt channel on the ECU. You can then span the boost target off the AN Volt channel

A time frame is totally unknown on this. It might not ever be done as it has not made it to the stage of being assessed as a viable project. If this project is finished there will be an announcement.

The two cams are offset from each other. We are expecting the first tooth on the LH cam to be at 54deg and on the RH at 139 after TDC#1

Hi Pat 1) Yes 2) Correct select the GM Siemens option.

Cam signals look mint in shape and size, however the crank I would say is the incorrect polarity. I would remove the crank sensor and check with a piece of steel and the scope to see a rising voltage as the metal approaches the sensor and a falling as it moves away.

It will be a two person job with a timing light. Light on #1 lead and check when cranking if there is spark and if it is at the right time. If there is then move on to fuel.

I should note it does not have to be the factory Nissan igniter.

Open loop uses the AFR table in the main fuel calculation (mathematical correction)Â so there is no need for any gain control. So to answer your question you do not need to have closed loop lambda control to use the open loop AFR correction.

The ECU has two sensors one is for MAP and one is the barro the MAP cal matches the MAP to the barro sensor at the same pressure as both sensors are measuring absolute pressure. So a cal on a 105 day and a cal on a 95 day will give the same result.

As your applications is a distributor based engine you will only have one ignition drive and one coil, so depending on where the rotor in the dissy is pointing will depend on which cylinder you get spark. Â Given you get spark this indicates the coil and ignition drive are good. You will need to check the timing when cranking to make sure its firing at the right time.

Sorry I dont. However you can check the ground and power with a multi meter. Ground will have continuity to the block and on the 12V you can see if you have 12V the signal will be the one left.

The parent company is actually Electronz and does both brands, The Vi-pec is the more expensive and as a result gets the extra functions and features. The Silver extreme was at the price point of the V88, When we removed the functions we also dropped the price to match. This resulted in much better sales.

lower the 6000 on threshold to 3.0 and see if that helps.

Yes if the coils do not have an inbuilt igniter an external one is required.

Have you tried a MAX of around 60%?

HI Leo In MAP mode you loose barometric compensation. This applies to turbo or NA applications. The engines VE gets worse as altitude increases requiring a reduction in fuel. We tested this on a a very large hill in central Otago (the race to the sky) The 135 turn course climbs from 450 meters (1500 feet)Â to 1500 meters (5000 feet)

Hi Trent We have this available in the Vipec range of ECU's but it is not an option on the Link ECU's

Map sensor will require power ground and signal out. It is wired in to the AFM plug. http://www.linkecu.com/support/documentation/g1-engine-management-documentation/gtslinkinstructionmanual

Hi fis Have you tried to use lower max and min duty cycles? Or is there any way to reduce the spring load on the motor?

The AFR table can be spanned off any of the options the same as the main table. The AFR table should ideally match the main fuel table and if you are using MGP for the main table this will be fine. In some cases if tuning in TPS you can have the AFR table on MGP to help compensate for boost.

Will need to start with the basics. Check for fuel and ignition at the correct time. You can do ignition and injection test through the software.

Hi Ethan No it will not work in as it relies on an OBD2 output from the ECUÂ which we don't support.

Put you filter levels to level one on both channels. Check the ECU Stats to see what it thinks your max RPM is if this is over the top high it can point to trigger issues.
