hi yes it seems to be improving on drive ability which is great but anything thing i have noticed is as soon as i let off the throttle to coast my lambda goes total lean to over 1.5 and puts engine management light on but as soon as i touch the peddle the lambda comes back up normal, i am still tweaking a few bits but it is definitely getting better following adams advice

Hi yes i have been doing what adam has suggested which is helpful and boost control has been disabled so it is only going to go to factory actuator pressure, i still seem to get a hesitation and missfire which is making me think timing map as the timing map being used is the factory base map for 370cc standard injectors not for 740cc, so wanted help from anyone who could help verify some timing table settings to help run better as it seems my knock sensor settings are currently off and dont want to risk knock, I understand i am getting some help just dont appreciate the judgemental comments from someone who isnt putting in any helpful advice, i apologize for coming across abrupt, i am a novice to standalone ecu tuning and want to get it right and safe

Right just like it seems on here the mapper does not have a safe map laying about for the same hardware i have installed on my engine, As for boosting it well i am not trying to go to 1.2 bar boost only factory 0.7 to ensure my pipes and turbos are all working correctly which should be ok on short drives, I have watched videos with regards to tuning but yet again they are based on other cars and other engines not the vg30dett, hence why i came on here to ask for help, not to be judged or slated, this is a LINK forum for the LINK ecu of which they do for my car and engine so kinda hoped someone out there could help and give proper advice. Guess this is why i dont join forums

Thats what im trying to do but would also like help with the timing map and any other settings on here as dont want to risk the engine driving it to a mapper which is over 100 miles away, so any help is really appreciated to get it as good and drivable as possible and give the mapper less work

Hi anyone else got any advice or willing to help please, i was kinda hoping actually joining a forum for the company who makes the ecu someone would have the same car and sort of setup and be willing to help a novice stand aloner

Well if you're able to help and can do any adjustments then please do and then post them/send them back for me to try and i will log the data again, i need as much help as possible

hi yes the ignition timing on the cas and the ecu have been synced correctly even checked directly on cylinder on with a Ht lead between coil pack and spark plug so i get a direct timing for the spark, ignition timing has been set to 15 BTDC as per manufacture information

hi i have attached the map and log i did with the car on a short drive and as you can see the log shows it only gets upto 20psi (14,3 none boost so about 5psi boost pressure) the base map is one supplied by link with the ecu just changed to run on the 740cc injectors and to try and keep fueling around 1.000 lambda or just under, 02.06.2022.pclr Log 2022-06-2 8;17;53 pm.llg

Hi anyone willing and able to help with my map on a 300zx vg30dett, running 740cc injectors, i cant hit any positive boost pressure as i get hesitation/misfire, i think its timing map as my fueling is fine and within lambda settings 02.06.2022.pclr ** Note this post was merged by a moderator from a separate thread since it was related to the same subject and user**

Or does anyone have a map they can and willing to send me that will run on the specs i have sent please

I need help with mapping the ecu to my car, i have used the nissan 300zx base map and made the adjustments for fueling to get within the lambda, but i cant hit any sort of positive boost pressure without missfiring so think timing is out on map and at the minute it is undrivable to remapping place, Quick run down is:- 300 zx z32 vg30dett, forged pistons and rods, rebuilt turbos, large fmic, seperate 2.5"exhaust, 740cc injectors ptu2 fitted uprated coil packs, running map sensor, innovate wideband, link air intake temp sensor, fuel temp sensor, fuel pressure 3.5bar on idle with a 1.1 raising fpr, egr delete decat system, on a manual box, hit only 3 psi before hitting misfire hesitation and plugs all good, Can anyone of you help adjust my tables if i send pcl and log files please
