rg500 Posted July 2, 2019 Share Posted July 2, 2019 Does anyone know if I can adjust the air fuel ratio as running a little rich after na-t conversion I am still running stock injectors and Ecu until I can get it mapped with the 550cc injectors and emanage Ultimate , I just wondered if I can get a controller to alter the afr as have seen the hks afr Controller I just wondered if that would work.

mellonman Posted July 2, 2019 Share Posted July 2, 2019 yes you can buy and fit a air fuel controller , apexi did one safr. but you really should just wait until you get the ecu fitted other wise your paying twice ,having the fuel right doesn't mean the timing will be , be patient dude Link to comment Share on other sites More sharing options...
rg500 Posted July 2, 2019 Author Share Posted July 2, 2019 Ok thanks for the advice I will wait until the ecu and injectors are in, the car is running nicely just a little rich showing about 16 on the afr gauge doesn’t go over that would it still be safe to drive like that .

Swampy442 Posted July 2, 2019 Share Posted July 2, 2019 Thats lean, rich is lower than 14, lean above 14 Link to comment Share on other sites More sharing options...

rg500 Posted July 3, 2019 Author Share Posted July 3, 2019 Sorry my bad running lean any ideas how to reduce it so I can drive it safely. Link to comment Share on other sites More sharing options...
Sheefa Posted July 3, 2019 Share Posted July 3, 2019 Get it mapped properly! You could just put larger drop in injectors in but I’d just bite the bullet and get it mapped asap Link to comment Share on other sites More sharing options...
mellonman Posted July 3, 2019 Share Posted July 3, 2019 you really need to stop driving this car until the bigger injectors are in and its mapped Link to comment Share on other sites More sharing options...

Noz Posted July 3, 2019 Share Posted July 3, 2019 (edited) It needs a professional base map to limp it from one location to another. My advice is disconnect the intercooler pipe from the turbo and throw on an air filter onto the intercooler pipework. So you just air filter into the cooler and bypass the turbo. It'll run like an NA and is low risk. Problem solved. Do not drive the car with turbo connected. Run it like an NA then just connect pipework when you get to mapping location. Intercooler only will be safe. Turbo can not be connected for any reason. Unless you like danger and explosions lol. If it's 16 AFR then try upping the fuel pressure. If you don't have a regulator. Nows a good time to buy one. If that doesn't solve the lean issue with no boost. You have another issue that is non NAt conversion related. Any AFR controller is just a plaster to avoid proper mapping. Edited July 3, 2019 by Noz (see edit history) Link to comment Share on other sites More sharing options...
rg500 Posted July 4, 2019 Author Share Posted July 4, 2019 iF I was to buy a afr controller which one is best one I have had a look and there is a hks afr but there are 2 types an L and a D which one is best suited for the car or is there another brand/option.

Noz Posted July 4, 2019 Share Posted July 4, 2019 You can't use an afr controller to resolve your fueling issue for an NAt setup. You need it mapped. That's why no one is recommending one mate. Turbo installation isn't just about the afr number. It's about the rev range variation of afr and timing. Honestly mate lol you can't use an afr controller to resolve fuelling issue you need it mapped. Link to comment Share on other sites More sharing options...
Frank Bullitt Posted July 4, 2019 Share Posted July 4, 2019 The fact she is running lean and not rich when you thought it was the other way should have been enough of a wake up call for you to get it mapped by someone who knows what they are doing. Treat the cause, not the symptom. If you want an AFR controller then have a search, loads of threads out there. Link to comment Share on other sites More sharing options...
rg500 Posted July 4, 2019 Author Share Posted July 4, 2019 She’s booked in tomorrow to be mapped Link to comment Share on other sites More sharing options...
