If you have a friend with one of those ECU programmers get your ECU tuned and garans you'll put out over 100 with stock stuff lol. Something like how technosquare does their ecu tuning

battleversiontc · 05-23-2009, 03:52 PM

nope cause i run it on my tc works fine

gwasabi · 05-23-2009, 03:55 PM

REally?! man I'm picking one of those up hahahahaha I was thinking of picking it up but someone was telling me how it only works on VVTl-i cars

gwasabi · 05-23-2009, 03:58 PM

If tat's the case then you can get VVTi controller and 1zz injector and TB and you will probably get a singnificant boost in power.

battleversiontc · 05-23-2009, 04:00 PM

yup cause you can adjust fuel from it and adjust the vvti activation point it makes a difference theyve been running on this in the tc and the 1st gen xb's for a while now they are cake to tune

gwasabi · 05-23-2009, 04:04 PM

Yea I heard.

when does VVTi kick in on our cars? I was thinking around 4000-5000 I'd lower it to like 1500 -2000 and up the af ratio a bit.

fuck my bad I'm thinking vvtli

battleversiontc · 05-23-2009, 04:05 PM

yup kicks in around there more like 5000 and 1500-2000 is to low the lowest i would go is 3000 or 3500 in hondas you cannot even run vtec that low 1500-2000 and anyways that low youd waste alot of fuel just cruising

gwasabi · 05-23-2009, 04:09 PM

Yea it'd waste alot of gas for sure but thats not something you should be saying if your gonna go turbo anyway hahahaha

Are you sure about the vtec stuff cause my friend had a integra running vtec controller kicking in at 2k

battleversiontc · 05-23-2009, 04:15 PM

yup anything below 3000 your not really doing much but making noise what your trying to do is make the low cam run out and then transition into high cam smoothly what he is doing is actually acting as a negative affect if he actually ran it on a dyno and ran to red line hed see he lost power by doing so cause hes shortening the high cam from doing its job and turbo normally builds boost at 3k so your not really wasting gas not unless you have a heavy foot and love to pound the crap out of it cause i still get 30mpg on my yaris i build both hondas and toyotas ive done everything possible to a honda so i know honda stuff and toyotas pretty well on tuning and parts and stuff

gwasabi · 05-23-2009, 04:18 PM

this is the charts for PE's stock engine tune

gwasabi · 05-23-2009, 04:20 PM

expensive stuff though hahahaha

battleversiontc · 05-23-2009, 04:23 PM

So when you hear people say "I got a vtec controller and I set vtec to 2,000 rpm so im mad fast now, u know they're a not bright.

Why? This leads into my explanation on how vtec works but, basically on a vtec motor there is a vtec cam lobe and non vtec primary & secondary cam lobes. Those non vtec lobes are optimized for low end power delivery. However, @ upper RPM, the small lobes cannot deliver enough air nor keep the valves open long enough to continue to let the motor make power.

Hence, the VTEC crossover...where the VTEC cam lobe takes over duties in opening and closing the valves from the secondary and primary lobes. Since the vtec cam lobe is much taller, it can now provide more air and duration the motor needs to keep making power @ higher RPM.

Now think about it. What does setting VTEC at 3,000 rpm do? It makes a cam lobe designed to work well at HIGH rpm to work at LOW rpm. Conversely, setting VTEC too high will cause the motor to start dying out, then JUMP foward when the VTEC lobes take over.

If u have or do get a vtec controller, try it one day.

Set vtec to 3,000 and see how much of a pig the car is down low. Then set vtec to say 7,500 rpm or something. See how the car accelerates, slows down, then springs foward again at vtec x-over. You may think that is the car making more power, but if you were to look at dyno graphs, you would see the torque curve fall off, then rise back up @ your specified vtec cross over point. The above is also a good way to determine a starting point for an optimal vtec x-over when you have done some internal mods and u would like to set vtec @ a certain point. Take a dyno pull with vtec set low, then another pull with vtec set really high.

Overlap the graphs and where the curves intersect where power falls off and where power comes up is where you should start to mess around with a crossover point. Now, I-VTEC is VTEC, with a twist. Toyota's VVTL-i is the same thing as i-VTEC. Basically, in addition to VTEC, the ECU reads and modifies both intake and exhaust cam timing to an optimal point at every point on the RPM band. This ensures the most efficient cam timing to achieve optimal hp and torque. Infinitely Variable valve Timing and lift Electronic Control. This is why the new RSX-S motors, although only making 5 more hp than the old Type-R motors, are making around 12 more lb-ft of torque - because of i-vtec.

gwasabi · 05-23-2009, 04:27 PM

hmmm I see learned some new stuff today

gwasabi · 05-23-2009, 04:28 PM

never had one of these so never really got into it so I don't know much about it hahaha all I know is AF mixture can be adjusteds so I put 2 and 2 together and was like WOW! that might be useful

battleversiontc · 05-23-2009, 04:30 PM

but you get my point why you cant set it to low thats why tell your friend hes doing more harm then good

gwasabi · 05-23-2009, 04:33 PM

Yea I understand and he doesn't have the car an stolen hahaha

gwasabi · 05-23-2009, 04:34 PM

maybe I'll get this and give this a try before getting turbo it might be useful

battleversiontc · 05-23-2009, 04:36 PM

yup get the power cam con one for toyotas cause theres two models one for honda and one for toyota
