Hey bro its Mike from Toronto. Check this out man. What does your fuel system consist of? I was tuning my car last night with my buddy. We put this sniffer tool in my tailpipe to tell us our A/F ratio. My fuel system is a 150Walbro pump with 450cc injectors. Now reugular driving before 3800rpm the program is super fat on the A/F ratio monitor. As soon as you get into boost at 4000rpm its starts getting really lean. By 5500 rpm in 3rd gear we where reading 16.1 on the monitor (super lean). Maybe this is what caused you your problems. So we cranked up the fuel pressure to 50psi with the vaccum on. Still no difference. We are majorly under fueled with this program were boost is concerned. We even had the injector taxed to the fullest on the millivolts and no dice. Our setup requires at least a 550 cc injector with a Walbro 255 pump. Just a little food for thought. But what a difference in peformance with more fuel after 4000rpm. The car was pulling like a bastard. I swear to you bro, we had to have added a additional 20whp to the car last night. I can't wait to upgrade my **** now. Hope this info helps any.

 

Thanks for the waste of my time.

Thanks for the waste of my time???????

I didn't know I put this info out for you. Last time I checked the thread said Attn: SpeedFreek, is that your user name?. We are both running his programs in our Zdyne ecu's and he hurt his motor. I don't have his email address but I know he posts on here alot, so do the math.

 

I did the math and it came out that your an idiot. Just because it says attn: doesnt mean you can fill up a slot that only pertains to one person. I think im just going to talk to everyone on the boards one at a time instead of useing the IM portion of this board like it was made for.

Cheese is my favorite food.....Hope theres someone out there that wants to know this because I know everyone else on the board who will read this wont care.

 

you impress me. If you are so hard up on the IM why dont you IM him to bitch at him rather than wasting bandwidth?

Rob

 

Thank you for posting this. I have the same problem with my setup. I am running a Zdyne, 450 CC injectors and stock fuel pump. I have a 95 B18B engine. When I used his LS tune my car really leaned out big time! I had to go up to 175+% fuel to keep my trusty ( ) autometer gauge in the green. I have a heavly modded PM6 tune that works well for me but I have had to set fuel to 200 % to get it to work right. I would like to try to replace my fuel pump with a 225 lh unit. We will see how it work then.

MIKES:

I REALLY appreciate the feedback. Mine was way lean (13:1ish) under boost above 5500. I'm not really sure how the friggin tune was so far off when I converted it over from Hondata. I'm not sure quite what your setup is, but I know you're built. I'm glad you didn't hurt your engine. I had to re-tune my entire fuel curve. The tune that I converted over from Hondata was evidently a big pile of garbage. My fuel setup consists of:

Stock 'teg fuel pump
DSM 450cc
Adj FPR w/ guage -- set at 40 PSI with the vaccume on

With an FJO wideband, I was able to tune about 90% of the fueling with the boost set to 10 PSI. I found at above the 5300 range I was running about 14ms @ 10lbs. I did some figuring and thta is putting me in the 80%+ duty cycle above 6500. I think just lack of proper tuning caused my problems.

89civic1.8T:

I think i'm gonna run an inline also, I may pull that stock pump out all together and just run a hose to the strainer in place of the stock pump. We've pretty much got the same fuel setup. I pulled my stock Hf pump outwhen it burnt up do to a clogged strainer(which caused me to run very lean a few times)......

Honestly i'm surprised my engine has held up this long. It's a good engine that i've had since my first swap, I wrecked thatone and pulled the engine for use in my current car. it's got about 120,000 miles on it....Some of those weren't to easy on the engine either. She's gonna get some TLC now tho.


For what it's worth guys i'm sorry that tune is such a peice. I've got a preliminary tune for my car. It's for the cams i've got but it may be closer than that crap i've got posted on my site now.....ugh...Sorry guys

top notch:

Don't be such a friggin know-it-all noob.

Maybe one day you'll have people that are willing to help you through troublesome times. With the attitude you've shown here though, I doubt it. Guys like MIKES and 89civic1.8T are what make this sport worth persuing. It's about respect and friendship among people with common interests. I get along with just about anyone, whether it's import or domestic. I don't see why you've got such an attitude with you double digit post count and 30 days worth of membership.

Kamin:

It's alright, many people used my tune in hopes that it would help us LS powered Zdyne users. Zdyne in it's infinite wisdom didn't provide a stock LS tune, even though the 90-91 'tegs were OBD-O like the 88-91 Civic/CRX's. It's good to get the info out, don't be so harsh on MIKES. He seems like a stand-up guy, we need more peeps like him around here.

I dont have an attitude problem. I am a know it all. The point was not to post crap that only pertains to 2 people because they are more then just u guys checking out this board. Just because you have been a member to H-T longer doesnt give you any power either. Now that the 2 guys this was intended for saw this, swap ims and emails so you can chat back and 4th and help each other.

 

I think this is a good post if Mikes wouldn't have posted this I would have never knew that anyone else was having the same problem as me.
Steve
I wanna put an intank walbro pump onmy car. I just did a drag install on a Type R and I don't like the inline setup. It's not for us with Zdyne's anyways. I feel a pump that delivers more volume at stock pressures will do just fine. and 100 bucks ain't bad at all.
BTW: My motor seems to be ok I did a compression test and got 185 all the way across. Tomarrow I wanna check my cam timing and adjust my valves. But just so you know we all still apreciate the time and effort you put in on making an LS tune. Thanks

 

top notch- Your the biggest dick head there is out there. You don't know me pal to be calling me a IDIOT. I know for sure you would NOT have the ***** to say that to my face, or you would be lying on your back holding your jaw, asking what happened?. You can take your 2 cents and fly a kite you noob. This is a very important thread. But seeing as how you know **** all about sharing info with others you wouldn't understand. These threads are here to help others. I am not the only one in here with a Zdyne ecu, so this is food for thought for all Zdyne users *******!

 

Sorry guys for my outburst. But some people have no clue what its like to just pass things that don't pertain to them. like commercals on tv. If you don't like it, change the channel. Just don't sit infront of the tv cussing. At anyrate my setup is:

B18A block bored 20 over
> Eagle rods
> SRP forged pistons
> TypeR oil pump
> STR blockguard
> ARP head studs
> B18A head ported by JG
> JG 1001 cams
> AEM cam gears
> Skunk2 intake manifold
> 65mm throttlebody ( stock one bored out)
> 450cc injectors
> 3 bar map sensor
> B18A LS tranny
> Stock flywheel lightened
> from 18 pounds to 13
> Clutch Masters Stage3
> clutch and pressure plate
> Aluminum crank pulley
> Buick Grand National
fuel
> pump ( works great & fits intank )
> Zdyne Gold ecu
> B&M adjustable fuel
> pressure regulator
> JG turbo manifold
> Richard Lee wastegate
> (supports 800hp, took that off my Buick too)
> T3T40E A/R- 60 M-10
turbo
> (Stock Buick Grand National turbo modified)
> 2 1/4 intercooler piping
> Buick Grand National
> Intercooler modified for front mount
> HKS Super Seq Blowoff
> Taylor 8 mm wires
> After market fuel filter
> to replace the stock junk.

 

Actaully it doesn't look like out setup are that dissimilar, aside from your forged components.

Engine:
Stock block/bore
Stock rods/pistons
Custom Web Cams(not sure how close to the specs of you JG's......share )
Crower valve train
GS-R girdle
Hand ported head(prolly doesn't flow quite as well as your JG)
Port matched TB
Skunk2 intake mani
B20 oil pump(same as ITR/GS-R)
Clutchnet stage 2 clutch setup
Port matched DRAG mani
T3/T04E .63 a/r

Only real difference is I twist my engine to 8K RPM, my cams make power that high

I don't think anybody wants you here anymore top notch, and since you probably have no good experience to use to help anyone out, why don't you go ahead and get lost. You won't be missed.

He was trying to get the attention of one person. If he doesn't know where a post is by that person, he can't IM them to my knowledge. Regardless of that, they are having a discussion which is good for everyone here. That's the whole point of these message boards.

Last, I KNOW your time is not worth that much. If it were, you'd be making who knows how much per hour and you would not be driving a Honda!

Well Said

 

Quit whoring the thread

 

Once you get your fuel issues sorted out, your car is going to really fly after 5500rpm. Funniest thing is I was beating C5 vette rolling in 2nd gear running lean. I will be changing my injectors and fuel pump this weekend and going back out tuning. If our tune pulls out a safe program I will hit you up with the tune. I don't want to go with a 720cc injector because this is my daily driver and its hard to get those bad boyzs to idle well without smelling toxic. 550cc is my best bet I figure since I won't be cranking it past 15psi on pump gas (Ultra 94) and 20psi with C16. I did a compression test last night and all cylinders were 185 right across the board thank goodnesss. My buddy Jack owns a Racetronix and his prices are pretty decent for injectors, and fuel pumps. http://racetronix.com/ Check it out guys.

 

I was running a GSX fuel pump with no *real* tuning and had lean out problems in high RPMs. This was when I was trying to reach 10psi!! I changed to walbro *regular* 255. No more leaning out. I think the intank will do you well Speed.

 

Actually i'm not sure if 550cc will do you. Granted they'll work for now, but if you get the itch to turn up the boost I think you'll be replacing injectors once again. Like I said before I'm tapping out my injectors after 6500 or so. I'm just barely holding a 12:1 A/F ratio under boost.

I have an FJO wideband O2 kit + datalogging, incase I didn't mention that

As we all should know fuel usuage isn't determined by boost but by HP made. So at 10 PSI i'm tapping out a set of 450cc injectors that should be good for up to 300HP......food for thought

Before I had my cams and 8000 RPM revlimit. I was able to out run a mod'd 3rd gen TT RX7 on the highway like it was nothing. It moved fast as hell then, and even when I ahd 1/2 compression on 1 cyclinder it felt just as strong. The only thing I can figure is when I started correcting my fueling and making more power that engine just couldn't hold it after all the abuse it has taken. My 1 cylinder took a **** after the last set of revisions I made to my fueling, which were damn near perfect.

12:1 under boost
14:7ish at most part throttle situations
13.5 at WOT out of boost
15~16 at idle/high vaccume cruising....yeah yeah still tad bit lean

 

Speed PHreak- you have difenately done your homework. What do you suggest for injector size and do you think the 255 Walbro pump is sufficent? Out of curiosity how much hp can 550cc injectors handle? It truely a shame there is such a distance between us, becuse it would be nice to hook up.

 

Heh thanks mike

I'm prolly going to find some 720cc injectors as soon as I get my engine put back together and broken in. But for now i'm just gonna stick with the 450cc for break-in purposes. 550cc injectors should hold 350HP at 40psi rail pressure, more HP can be made/held with higher rail pressure.

Just remember, the stock regulator and any aftermarket adjustables are 1:1 ratio. So once in boost the rail pressure gets jacked up by however much boost you're running. (40psi fuel pressure @ 10psi of boost = 50 psi of actual fuel pressure )....Just have to take that into account with your fuel pumps flow volume. I'm not really sure at what rail pressure the stock pumps start to get ineffiencent at. It's prolly somewhere around 50~60 psi though. So that 255lph pump you've got ought to be plenty over the stock 140lph-ish

I was always confused how stock F/I cars could run such tiny injectors, even the GN has what 35lb/hr injectors? Guess it's a result of thier small turbos and factory HP limiting......
