[maxim240sx]

I have a 92 talon FWD with the following mods.Freshly rebuilt engine,big 16g,evo exhaust manifold,2.5" UICP,greddy bov,walbro 255lph,stock injectors, 2.5" exhaust,MAS lower honey hacked,screw backed out.boost controller.Now here's the problem.I get fuel cut at WOT in 2nd and 3rd gear when I run 16psi.I would really appreciate a simple answer for the problem.Do I need a safc?Bigger injectors?Or a new MAS like a GM 3.5" with translator?Thanks

Injectors + someway to adjust for them such as MAFT or SAFC.

So I have to get bigger injectors?So I guess the stock injectors are maxed out now when you get fuel cut?

 

[90AWDTalon]

You get fuel cut when the ECU reads a set amount of airflow. It cuts fuel as a safty, because you are close to maxed out. Adding new injectors by themselves wont do anything accept make you run rich, because the ECU doesn't know you have anything different than stock. But if you add new injectors and an SAFC or MAFT, you set them to correct for the new injector size. To do this they send a lower airflow reading to the ECU, this doesn't eliminate fuel cut but it moves it furthor out.

Ok so if I get some 550's and a MAFT then I probable won't see fuel cut anymore with my current state of tune?Thanks for the answers

remove all the restrictions from the air can. there are numerous sub-12 sec dsms in this area, and all they've done are the free mods to the air can (well, they obvioulsy have bigger injectors and fuel manangement...). i didn't completely remove restrictions from my air can and i have big injectors with an safc2, and when i turned the 14b up to 19psi, i still hit fuel cut. that got me under the hood cleaning the thing out really quickly...

Fuel cut is caused by air flowing past the meter...once there is "too much" air flowing past the meter the computer cuts fuel which is what you feel, its not because you aren't flowing enough fuel or that you cant flow enough fuel...its because the ECU sees a lot of air and no matter what fuel mods you have it is still going to cut unless you get some way to hide the air or something that eliminates fuel cut.

There is enough info about fuel cut on tuners to make a book!

HKS makes an electronic fix for that.

Its called a fuel cut defencer and it was in the november import tuner magasine on a 92 eclipse.$150 retail.

thats the route I'm gonna go. You don't have to hack your MAS.

It caps your airflow signal, which if you go past that, you just run lean and destroy your motor instead of fuel cutting.

Not an intelligent buy in my opinion.

OK so can I just get some larger injectors and either a safc or maft to control them?

free mods, don't forget the free mods!

Get the fuel cut removed, if you have an EPROM ecu, get a new chip stage 1-3
