the engine temp sensor is new. maf looks ok. the iat needs to be tested, the o2s look old. ill test the fuel pressure soon. could a bad fuel filter be to blame? car isnt sluggish and doesnt bog. when you say evap, do you mean the egr valve?
i want to remove the egr function as well as the smog/air system. are there issues when doing that? ive heard conflicting info. im going to do the coolant bypass soon and want to do the other stuff at the same time.
so how to i figure out what code reader will scan a 94? do generic ones normally not scan a 94 car?

I checked the iat and ect today everythings fine. 5volts to each. is there a way to test the mass air meter? i still need to check the injectors and o2 sensors

www.aldlcable.com and be sure to get the correct connector

10 mpg of course means that you are consuming more fuel

either your tires are way underinflated (Obama told us to check our air pressure)

your brakes are dragging

you do all driving within LA or NYNY

someone is stealing your gas

your gas station's meters aren't calibrated and you're only getting 1/2 the fuel for which you are being charged

your fuel tank is leaking

your tranny is slipping so badly that you are turning 4500 rpm going 10 mph

or you are running very rich

if it's the latter, then chances are an O2 sensor isn't behaving

you can find a wealth of data by capturing a data log. Then, if you want it tuned, especially to delete EGR or even VATS, after you capture the log, send it to Solomon at www.lt1pcmtuning.com and he will tune your car as well as help you interpret the data

Can I make the cable, as in solder in a usb cable to my aldl wires?

here is where I shake my head in amazement

please allow me to perform a CBA for you (cost-benefit-analysis)

buy the cable from aldl and also tuning service from solomon for a whopping $130 total

you claim to only get 10mpg and since I'm confident that you aren't using cheap gas, but are using premium, it's about $3.20 per gallon

let's say you drive 250 miles per week which is 25 gallons x $3.20 = $80 per week fuel

if you get a tune, and that's all that is needed then you should see around 18mpg at 250 miles per week is approx 14 gallons of fuel x $3.20 per gallon = $44.80 per week or $35.20 savings per week.

You achieve payback in less than 1 month even if you paid 2 months finance charge on a credit card for the $130 purchase

then let's explore the annual savings and assume month # 1 pays for the cable and tune, then month 2-12 is incremental savings or 48 weeks x $35.20 = $1,689.60 additional savings just in year one

so, to be brutally honest with you, do you really want to **** around over a cable or do those cold hard numbers slap you in the face and tell you what you should be doing???????????

Sorry if this seems harsh but when you look at the above, the correct method is obvious.

Its not a daily driver. I have maybe driven 100 times since may when I bought it. I already spent hours reading stuff on that site and have software.ive put a tranny in it, the thing is costing me, and why buy a cable if I dont need to? You like payn for stuff you can make? And ive seen guys soler in serial connector on plenty of cars.basically you dont know and they arent telling or no one would buy a cable,lol

so lets say i order the cable from aldlcable and i cant scan my car with a innova brand scanner, whats to say i dont have a problem that will not allow the cable to work either?
if i can get some more clarification as far as why the innova brand cant connect to my ecu then ill order the cable , but i hate to order when moneys tight and find out i have a greater issue like a bad ecu, and there was a hypertech piggy back on this car so i wouldnt be surprised if my ecu has issues
and are some cables not compatible with certain software? is the and advantage using a serial cable instead of a usb? like say serial with usb adapter. my laptop has no serial its too new

i just ordered the cabl form aldlcable. hopefully it works.

now if i can just learn how to use tunning software. whats the easiest for making changes?

that's a big thumbs up

for me, the easiest was to spend $70 and use Solomon lt1pcmtuning.com

not only do you get his experience but it's good to have another informed opinion. And then, the tune is customized for your vehicle.

he'll tell you in a heartbeat if it looks like you may have other issues such as O2's, exhaust leak, other sensors

i was hesitant on ordering it since i dont know if theres an issue with my ecu or the connection to the aldl port. but its ordered and i should have the cable and stuff by friday.
theres alot i want to learn here, especially since i mess with hondas alot and some of the same stuff applies to the obd1. and i really just love messing with cars period
Wow they already shipped my order! the guys at aldlcable/obd diagnostics are great. i called and had someone right away on the fone and got my questions answered fast.
if anyone is considering the cable get it from them. i cant wait to start playing with stuff:)

if you think they are good, if you decide to use Solomon for a tune wait until you get a load of his support. I was pleased with how the car was running by the 2nd datalog/tune and he kept wanting to get it perfect. After 1.6 rr's and replacing O2's because of a rich condition, I did a "re-tune" which was only $35 and at the same time i had VATs tuned out.

his customer service is the likes rarely seen. he spoils you

well usually thats how real car junkies treat eachother:)

i just got some new o2s and turns out my o2 socket isnt deep enough for the sensor! gotta run to harbor freight to return it and get the offset o2 socket

changed my fuel filter and one o2 sensor so far, the one i pulled out looked kinda green colored, is this normal, its really clean too, bosch brand.green tinted

Replace the Bosch units regardless. Bosch O2s are notorious for dying.

i did, and i got my aldl cable, havent really found anything wrong with the car except the idle seems to be set at 550rpm. and i cant change it
