How much will an after market ECU run me and how easy are they to replace... where can i find one ... which is the best and do they actually increase any... horsepower such things



thank you

What do you mean? Do you want a standalone, piggyback or just a chip? Standalones run in the $1000 price range and way up, piggbacks are usually around $500 and chips range from $100-300ish...

to switch to speed/density it's going to cost a decent amount of money, this generally involves switching out the ECU entirely to a standalone.



If you're on a budget, you can get some level of tunability with a piggy back like the S-AFC, but you'll still have the air flow meter.



and yes, it will typically result in gains of horsepower, usually throughout the entire rpm range, presuming you take advantage of the added control and tune the a/f mixture for better performance.

ok thank you ... yea the ecu would prob. come after my exaust and intake and Fuel mods then will come the ECU but i gotta get a job First ... and sell the POS Fiero

fuel mods?....if you get a fuel pump ur ok....but as soon as you upgrade injectors you NEED to have a new controller for them..... stock fuel maps with more powerful injectors = boom



if you get new injectors, be preppared for an EMS, along with dyno tuning (unless you know what you are doing), and be ready for some frustration - but then some fun

what does the power of your injectors have to do with anything?



if by more powerful you mean higher flowing, usually rated in cc/min, I don't understand what logic you are using to get to your stock fuel maps == boom



it will run rich with larger injectors and stock maps, no boom, just no zoom-zoom, more like cough cough sputter sputter, ah **** it won't start she's flooded.

yea....more powerful i meant higher flowing....



and then yea itll run super pig rich, then it wont start after a while.....maybe not boom....i should change it to = BAD



i saw hulk last night so im into BOOM

So i can do an upgraded Fuel Pump but not exactly upgraded injectors without needing a few more mods = bottom line?

it depends on what kind you want ive seen haltec's go for 900 i have seen mircotec's go for 1000 and mirco tec go for 1300 so its all in how much you want to spend
