I bought a set of Needswings Manifolds from Evan (cruzinquik) and there fantastic...only problem I have is when I put the car in manual mode and go flat out through 1st...2nd.....3rd gear in 2nd gear it redlines for ages and takes awhile to go to 3rd and the same problem in 3rd sometimes I even have to let off for it to change gear then stomp on it again.

My question is, could this be due to the extra air going to the engine from the manifolds? meaning i'd need InMotion to reflash my ecu again or could this be something else? Id rather not send me ecu across the world again. I was nervous enough the first time lol.

 

it really needs to be tuned with the added air and HP.....because you might be leaning out at those higher rpms...no way to know unless you are logging...do you have any gauges in your car?

 

Hey Doc, I dont have any gauges at the moment, I already purchased the inmotion custom tune when I got a cold air intake and pulley, i know another tune would optomise the manifolds but I thought surley due to the first tune the car would be getting enough fuel to compensate for the manifolds....hrmmm may be looking at another 2 weeks without the car

 

if you aren't going to have gauges to keep an eye on things, I would let inmotion know of your change, and send it off...you can check with Rob, but this is the reason I am not driving mine hard with 240's manis...just don't know until I get the Zeitronic dashdaq installed to do some logging in order to get the best tune possible...when you are revving that high, for what seems to be a long time, it could be lean, or it might not, but I personally would want to know....but they make a big accelleration difference don't they...

 

You could be right Doc, I should get some sort of A/F gauge installed. HUGE difference they make boost just builds up so much quicker and its on tap down low the car is a beast its just when I get to around 80mph+ that these problems happen....Its so annoying being in Australia everything takes so long to happen lol. My fiance' might be getting a job in L.A early next year so atleast if we move there and I get an SRT it may be 2 or 3 days waiting for an ECU rather then 2 weeks lol

 

Expensive city.......but, yes, I would think you could overnight it from LA...lol....just a tad further down under....

 

i wasnt going to say anything until jerry responds to the logs i sent him but i sense an air of emergency here.

i bought evans n/w dual cai for my 32. now i have the c3 with a number of mods and a custom dyno tune by e/c. so im thinking no biggie lets do some high speed runs and check the data. off i go run 2 passes at 158mph at 100% load and pop the sim card into my laptop.
what i saw made me weak and almost pass out!!! 18 AFR AT WOT!!!! afr's are out of sight. starting at 14.7 and zooming as high as 18 at 19 lbs boost.
with the addded air that these componets can deliver i believe a retune is mandatory. DO NOT RISK YOUR ENGINE! my outside temps were 46* and anyone who constantly mods without datalogging is riding a ticking bomb.
invest in a zeitronix wideband O2 sensor at the least. send the logs to rob and let him decide what course of action is necessary. i think theres an inexpensive O2 setup for sale right now on the forum.

Wow 18AFR is bad.....did your car do what mine is doing Steve? e.g. hesitate to change into the next gear at WOT?

what is the AFR meant to generally be at? since i dont have any AFR gauges or readings at the moment I might take my car to a dyno and get them to do a AFR reading for me aswell....if your car is at 18AFR and not hesitating like mine I dont even want to imagine what my figures are...but its wierd because like I said I bought the custom tune from InMotion so yeah I wouldn't be getting as much fuel as I should but Im sure they added a good amount of fuel for the pulley and intake so i didnt think it would be this bad.

Doc on a side note is L.A expensive to live in compared to other cities in the states? my fiance' and I have been there twice in the last 4 months and we were like Oh My God how cheap is everything here lol...price for gas in L.A is around $3 per gallon in Australia its around $4.50...not to mention everything else is cheaper in L.A then Australia cloths, food, etc etc

 

Well, then, I think LA would be a great place to live....but come to the midwest, where the laws are more relaxed and gas is 2.76 a gal....lol

 

$2.76!!!! man you guys really do live in the lucky country lol

 

actually my issue was traction!! broke traction in 3 gears. what you are looking for is afr's in the high 11 to mid 12 range at wot. in retrospect i most likely doubled the amount of air going into the engine from my modded stock setup. add the density of 46* air and there you go massive lean runs. i thought my tune would handle it easily but dataloggs dont lie. as mine is a toy its parked until jerry sends me the cables to retune. maybe you might consider removing the manis until you get a setup to log then send the data to rob for his input

btw gas in my town is 2.59$ a gal

 

yes sir, we do...and that's today's price...it ranges from 2.50-3.00.....but, building codes, environmental laws, well, heck, all laws for that matter, are a lot better in the midwest than Kalifornia, the USSR of the USA....

 

GREEN?........... we dont need no stinking green!!

 

haha you guys are to funny I should start reading up on the good old U.S of A!

Steve do you know if our cars have an inbuilt Air Fuel reader? if it does then the link you gave me, I can just get the OBD II port KiWi and I'll be able to see my AFR on my Iphone...if not I'll just get the standard set up and get a bung welded somewhere on my exhaust and use my laptop to see my AFR

 

By the way this odd behaviour of my car resulted in me getting my assed kicked by a brand new VW Golf GTI.....the guy found it really ammusing, when we got to the lights after exiting the freeway he said "I thought it would be faster then that" I explained to him i'm going through tuning issues....I think he thought i was using excuses! little does he know how much of a monster our cars are lol man id love to see him when the cars running right.

 

doc and 32 are only partly right. my midwest relatives talk sh*t about my home state all the time...while they're freezing their asses off and there's a distinct lack of variety compared to what we can do here. they say l.a. sux because of the lakers and traffic. i say only the traffic sux. but this one fact does stand out. they sure do come and visit us all the time....

 

i think the o2 sensor for the ecu is narrowband. you need to weld a bung in the exhaust to setup for wideband. i put mine just before the oem o2 sensor but rudy would prefer it goes after the oem and before the cat. theres a small space to do this but you have to drop the exhaust to get to it

 

no need to worry. i have been to cali. didnt impress me at the least. its like a big miami! ill ski in the east go to the gulf for my sand and sun and i enjoy the cold, it lets me know im alive!

 

TN isn't cold....lol......no offense, but you can have Kali....too many laws I couldn't nor would obey....other than that, it's an 8hr drive to the warm if need be....

 

Sorry both of you are having problems. Both of those mods were important to my 11 second timeslips. The tune even more important. 32Krazy! those are insane AFR's and hope your tune get's worked out. Good thing your datalogging.
Kolevski- I would unplug your battery and let the ecu reset. Then take the car out and drive it about 45 mins with normal spirited driving for the ecu to adjust. I always did this when I added a part. Hope this helps, and get on the phone with InMotion as well. The shifting issue seems more like the ecu hasn't adapted. Still suggest as we've talked before to datalog.
