Tuning

And if a CJ can get gains from retuning why can't a CE? Bet you the AFRs are running just as rich (if not richer) on a CE too ;)
 
They are actually very close to being perfect.

whats perfect fuel ratio, 13.something?
and what is the graph on the right, is it degrees of adv/retard timing or degrees of air temp or somethign like that?
 
hi just a quick question, iv got a 99 lancer ce and iv fitted a pod filter and RPW 4-1 extractors with 2" exhaust and 3.5" cannon. is it necessary to upgrade the stock ecu??

cheers

you could get a tune to get the most out of your current exhaust setup
 
No idea if you can get flashes for CE's, if you could being the car is that old it would be more talked about.

I'd imagine you'd have to go standalone, either way you are not going to get great benefits out of what it costs you ($1000+).
 
SAFCneo is another option.



flashing the stock ecu is usually a good thing. personally i gained about 30kw and about 2L/100km in fuel economy from a flash tune for the vr4

the gains at that point will not be worth the cost, if u have the $1000+++ to throw around and dont have any better way to spend it then go for ur life

altho in saying this if u plan to keep ur car and modify it long term (as in years into the future) then it may be handy to get one as u may need it later down track

but at this point the cost will outweigh the performance gained

also to answer your question no it is NOT 'necasary' to upgrade the ecu at that point, your cars air fuel ratios and timing are all still going to be working the same, u need a ecu upgrade when u start working with cams, compression, timing, forced induction or any other extreme mod
 
You should be able to get an ecu reflash tune done, na autosport can do it. But have heard a few bad things about them how when they changed owners (formerly Neil Lowe) that they're still learning to tune properly. Apparently though Neil still does tunes occasionally. But this is all heard 2nd and 3rd hand...
 
As far as flashing CE ECU's are concerned I personally haven't heard of anyone doing it to their cars, but I have seen many people myself included running a SAFC as a piggyback to the standard ECU. From a 4g15 with intake, headers and exhaust running the standard ECU pushing about 50kW, tuned with a SAFC Neo a result of 54kW was achieved. This power increase was all the way through the rev range.

So for your instance I would recommend getting a piggyback and getting it properly tuned.
 
I've seen 4g15 definition files for ecuflash so people are doing it, just because some people haven't heard about it doesn't mean it's not being done. Not all ce's are compatible but rpw would be the best bet to find out if your ecu is.
 
We can reflash some CE lancers, the CG 2.0 can definitly be flashed and we are working on the CG / CH 4G69 models right now.

not sure about the 4G15 models, but the CE is around a 50% chance. i actually need to play around with them some more to finalise the in procedure.

Reflashing is a great way to tune for medium to high level of modifications, cheap to tune as well
 
I'm with speed merchant, no point spending big $$$ for 50 kw. can pick up safc for 100 - 200 ish these days anyway and i doubt a tuner would charge more then 200ish to tune it..

Can you reflash the CH 2L?

Thanks for clearing that up, makes sense not to throw money at it if it ain't needed :)

i believe the CG and CH 4G94 are the same engine/ecu could be wrong tho. but iv read only certain series numbers can be flashed.. thats what its like on the 4G69 anyways.
