Transom Posted May 10, 2020 Report Share Posted May 10, 2020 Hi I have a few questions I would like to get clear before I start wiring New g4x atom - motor is Mazda kfze v6 with ITBS and stock injectors toyota coil on plug coils crank trigger 36-1 and VR sensor- have option for a cam sensor in old distributor housing with stock hall sensor have been reading here and on hPa about tps only and alpha N tuning main questions so far are is there any benefit to add the cam sensor and go semi sequential injection ? If I set for batch fire it only allows 2 injector outputs - can I run 3 high impedance injectors on each injector output ??? Or is it better to go semisequential and wire injectors in pairs ? If I only need 2 injector drives can the 2 spare injector drives be used as ignition drives ? Or is wasted spark and batch fire the easiest simplest option ? Have looked at fuel maps for alpha N setup with RPM on X axis and TPS on Y axis and using very gradual throttle values to help tip in - like 5% 10% 15% at the start then ramping up so that makes sense - what about ignition map ? Same with RPM on X and TPS on Y axis in the same sort of curve mode set as BAP There are quite a few of these engines converted to itb worldwide but 95% of them are on MS - I do have access to a good ripped stock ignition map and have looked at a g4+ map on here but it’s not itb Really trying to keep this as simple as possible only other outputs are fuel pump - Davies Craig water pump - and radiator fans - no ac no IAC no power steering idle up next purchase I’m looking at is spartan 2 wideband Any ideas thoughts appreciated thanks for reading wall of text Quote Link to comment Share on other sites More sharing options...
Adamw Posted May 10, 2020 Report Share Posted May 10, 2020 I cant see a good way to do semi-sequential on this engine due to the 123456 firing order. So to keep it simple I think I would do multipoint group. You can use 3 drives wired to a pair of injectors each and set active drives to 1-4. Ign will have to be wasted spark. Spare ign drives can be used as aux outputs, but spare injector drives cant on the Atom. I have attached an typical ITB fuel map (modelled fuel equation) and Ign table that will be a decent starting point. ITB Fuel Table 1.lte ITB Ignition Table 1 (+ °BTDC, -- °ATDC).lte Quote Link to comment Share on other sites More sharing options...
Transom Posted May 10, 2020 Author Report Share Posted May 10, 2020 Ok cool I was having a play around looking at multipoint group at could only seem to get INJ 1-2 active but will try that again and have a look at settings provided and help file again Theoretically with that and wasted spark setup the only other things required for a start are - Timing setup - calibrated TPS - engine coolant temp sensor table - IAT table- and whatever Lambda setup I choose So good to be using an NZ made product with outstanding tech support Quote Link to comment Share on other sites More sharing options...
Adamw Posted May 10, 2020 Report Share Posted May 10, 2020 Oh, I forgot to say also, if you are going to run a missing tooth crank wheel, then there is no need for the cam sensor in this multi-group/wasted spark set up. Set sync mode in trigger 2 settings to "none". Quote Link to comment Share on other sites More sharing options...
Transom Posted May 10, 2020 Author Report Share Posted May 10, 2020 Yes thanks I figured that and it gives more room back of the engine - last model of this engine had 36-1 and coil pack so I bought the trigger wheel pulley and the cam blanking plug and have now depinned that trigger from the link loom Quote Link to comment Share on other sites More sharing options...
Transom Posted May 10, 2020 Author Report Share Posted May 10, 2020 ok so how do i get those tables into my setup ? .lte files? have loaded pcl tune files before and used the clipboard to grab tables from on tune to another but how and where can i use them after download ? okay got that import from file ..... time for more reading i think Quote Link to comment Share on other sites More sharing options...
Transom Posted November 8, 2021 Author Report Share Posted November 8, 2021 So it’s 18 months later and I have had first start successfully @Adamw thank you for the maps above it got me going and heading in the right direction Slowly adding wiring and inputs and tidying up Can anyone point me at a calibration table for Spartan2 wideband controller ? also for std Mazda ect sensor Denso – 179700-011 or – 179700-0140 Or 179700-022 Quote Link to comment Share on other sites More sharing options...
Adamw Posted November 8, 2021 Report Share Posted November 8, 2021 For the spartan 2, use Linear cal 1, 2 or 3, set up like below. For the temp sensor use Std Bosch NTC. Transom 1 Quote Link to comment Share on other sites More sharing options...
Transom Posted November 9, 2021 Author Report Share Posted November 9, 2021 (edited) Ok wideband sorted thanks Also Fuel main settings multipoint group Equation traditional active drives 1-4 ( only 3 connected in pairs ) Injection Rate per Engine Cycle = 2 Is this correct ? Load BAP Master fuel = 10ms - started at 35 and dropped it down as very rich on that basic starter fuel map supplied Edited November 9, 2021 by Transom Dud ect sensor = question solved Quote Link to comment Share on other sites More sharing options...
