Default chipping toyota ecu

i know this is generally a honda site but u al look pro at turboing so ill ask neway

i was wondering how and where i could get my ecu re chipped to read boost and to re map my fuel curve, ive had an safc before and ive doen swaps and stuff but ive never dealt with turbocharging my car before

is there a program online i could download and buy a cable that would attach it to a laptop or computer or would i send it somewhere?

thanks for the info

I think this ask been explored before and As far as the responses I remember from the past, the answer is no. I don't think there is any other form other then Megasquirt or an AFC

i know uberdata nd z dyne wont work but i really dont feel like running boost on my stock ecu

are there any ways i could safly run boost on my stock ecu w no safc or re tuning my ecu?

i was panning on just upping my base idel Fp from 36 to 42 psi and running 320 cc injectors...but other than that is there anything that i can do?

thanks

I guess I'll go ahead and ask since it will be asked sooner or later. What engine, car etc...

If you are running a 4age or a 4agze, there are several things people are working with. There is a company called EL Prototypes that apparently makes some some sort of ECU upgrade for the 4ag motor. There is also a chip of sorts called the Unichip. I am not familiar with this at all but all of the local aw11 mr2 guys swear by it. If none of the above ecus work, there is a piggyback system called the grunt box that works in conjuction with a 4agze ecu and utilizes the cold start injector. Head over to www.mr2oc.com and read up. They have all sorts of info if you are looking into the 4ag motor.

Also, if you have a MAF toyota, the afc will not work. I, as well as a jillion other people, tried this back in the day and it doesnt work.

e well i have an A series motor but its not a good one, its a 4afe... but i have a 4agze sitting in my garage im swapping the bottem ends out for (4agze is stong and an overall better motor as wel as can handle lotsa boost) i want to boost this setup right after i swap the bottem ends out...

but yea i have a maf sensor, so basically what ur saying is other than running the gze injectors and upping my basse idel FP im SOL....

oh yea im still using the stock 4afe ECU, do you think is be able to use a USDM 4agze ecu on my 4afe? becuase it would read boost, as well as there basically the same type of motor with difrent head (f head is economical and g head is performance) but im pretty sure it would work...

so yea if i just use my 4afe ecu im pretty much screwed
oh yea the turbo is a 300zx T3 wastgate is set at 5.5 psi

I think your best bet would be to head over to www.mr2oc.com and ask them. I am not familar with the 4af motor. I know it is in the same family so in theory it should work. But definatly check over there. They should be able to help you.

if you just turn up the fuel pressure and put in bigger injectors with no controll you WILL blow your motor up ...god damn i dont know how many times i have told peepz this, you cant put bigger injectors in unless you have a way to controll them....either use megasquirt if you want real managment, or keep your boost below 7 psi and run an fmu with stock injectors, or GO HOME......

my only option for ecu tuning is to send it into JET, its $400 tho but they make it boost capable and re map ur fuel curve...but i dont really have that kinda money
