i was hoping if anyone can help me out i am looking for someone with similar upgrades with a MS tuning file to at least get my car started. and taken to a shop to get dynotuned. the car is a 98 RS 420A
i have noticed that some of the sensor plugs arefor the 97 years such as the O2, IAT sensor if that makes a differance

60mm tb
obx intake (bored to 60mm)
OBX high volume fuel rail
24lb accel injectors
Vortech SFMU
aeromotive 1:1 fpr
walbro 255l high preasure pump
wiesco 8.8.1 pistons
eagle H-beam rods
clevite rod bearings
meling high volume oil pump
new water pump
stainless steel valves
lifters from turbo pt cruiser
all new gaskets...mls for head
msd ignition
ngk copper plugs
new valve seals
60trim turbonetics turbo (good for 450whp)...so it says...i will be finding out
turbonetics wastegate with atmospheric dump tube
hks super sequenciel bov
arp head bolts

i will be putting in 48lb injectors and the complete 420A MS kit from paul over at symtech labs. from what i have read 32lb injectors are the highest the computer can compinsate for anything higher and it wont start. if i am wrong let me know

contact paul for a map.he sold you the MS.

You can download our base MSQ files, or MSQ files from other users' working environments from our MSQ File Respository:

That is false, Megasquirt can control any size injector, both high and low impedance. There are practical limits to consider, but you should not have to worry about those until you approach sizes in excess of 1200cc/min (110lb/hr).

Why?

I too am wondering about the fmu, an fpr is probably what he means.

I'm running 1000cc's saturated as we speak......

i was told to use the 1:1 regulator to help the transition into boost fuel presure it would help smooth it out



i was also trying to say that the ecu stock with no megasquirt the injector size could not exceed 36lb.


sorry for the confusion i did find the MSQ files on the website thanks for the help i think im gonna go with some 750cc and 20 psi boost unless anyone has any objections

You will need a 1:1 AFPR, but not an S-FMU. It's technically possible to use an S-FMU with Megasquirt, but it's completely unnecessary and unwieldy. The 1:1 regulator mechanically compensates for the boost pressure inside the manifold. With the two pressures equalized, Megasquirt doesn't have to do any extra calculations and you get greater use of your fuel injectors.

i also only bought the regulator due to the fact that i i only bought an fmu mut later got an sfmu for only $100. I ONLY USR THE regulator for my fuel presure gauge now. and let the sfmu do all the work. when i put in my megasquirt i am going to get rid of the sfmu keep the 1:1 get some 750's and run 20 psi boost.


on a side question i have a wideband from glowshift.com it is accurate it reads the same as the shops when i got my car dyno'd. what i want to know can i wire that to the MS or do i have to get another one. also do i wire it before or after the controller if i can use it without screwing with the signal they will both see
