1600 16v on 1400 16v ECU, would this cause running problems?

[Dod]

I'm running my 1600 16v on X14XE management as the 1.6 gear was full of water. The car seems to hesitate and not pull properly, almost like its missing. Is the 1400 set up causing the upset or should I look elsewhere?

[Stuart]

needs more fuel

[Dod]

Whats causing the lack of fuel, is it the 1400 set up? Also, would the addition of a performance "Super Chip" cure it?

[Stuart]

get the right ecu for the job.

Someone on here a few years back tried to run a 2l 8v on a 1.2spi ecu... it ran which was impressive but not for long lol

[Sloth]

your fooking kidding???? thats nuts./\

[Dod]

I know the SPI ECUs learn as they go, as in a 1.2 ECU will Run a 1.4, are you saying the baby XEs are different and the problem is the ECU?

[Plug]

/\ thats what i reckon. the managment will be giving it enough fuel for a 1.4

[Stuart]

your fooking kidding???? thats nuts./\


nope, some tool told the muppet that it would work lol

[Shaun]

yeh wont be getting enough fuel mate, mate had his running on 1400 ecu fpr a few months and ran like **** until he fitted the 1600 ecu

[Dod]

Cheers lads, lots of love. X

*thinking aloud*

if you worked out the percentage of power increase between the 1400 and 1600 then if you used injectors that were the same percentage increase over the 1400's would this not supply the right amount of fuel?

[Adam]

Actually some of the later 1600 16v's came with 1400 16v ecu's, and i know some people have run vice versa...... 1600s probably had larger injectors

Just to add, My 1400 run a 1600 ECU for a bit, ran like crap, overfueled and was crap so if that helps.

I've got the secondary air valve removed, I know it just helps burn fuel before it reaches the cat, it shouldn't make any difference if removed should it?

I've got the secondary air valve removed, I know it just helps burn fuel before it reaches the cat, it shouldn't make any difference if removed should it?

All this valve does is inject air into the exhaust to change the mixture, it effectively leans it off without affecting the engine which makes the exhaust hotter, which in turn heats the cat quicker making it start working earlier.

It does nothing related to the fuelling or ignition maps.

Spot on /\

[Dod]

Well, its been out on its frist 20+ mile run, pulls alright but I'd imagine with the 1600 management that it'll be twice the car. Cheers lads.
